1.1. SAI

The SAI consists of the following components: The acronym SAI stands for Sensor Actuator Interface. It is a compact-designed distributor and collector of signal lines.

• An I/O section: to connect the signal lines. • A settings section:

to set the network addresses and insert the jump-ers for the different electric potentials.

Signals to and from the process in field installations are often controlled from a central point, for example, by a PLC or industrial PC. Typically, the distance between the installation and the central controls is significant. The resulting costs for installation and materials for the cabling are high. This in turn increases the susceptibility of the system to interference and errors.

• A bus / power section: for the connection and loop through for the supply voltage as well as the bus connection.

Weidmüller offers the following I/O versions: • M12 16DI with 16 digital inputs.

• M12 16DI / 8DO with 8 fixed digital inputs and 8 individually configurable inputs or outputs. The use of SAIs has proven successful under numer-

ous conditions: • The signal lines of the peripheral devices are bun-

dled together at the process in the installation and connected to a bus.

In addition, Weidmüller also offers: • Network components for the Fieldbus systems

mentioned above • Signal lines are connected simply and conveniently by means of Plug and Play. • Sensor / valve connector cables

• The controls are at a central point • Plug-in connectors and twin-plugs • The reliability of the data transfer is guaranteed by

a bus system. • Tools

1.2. PROFIBUS-DP

PROFIBUS PROFIBUS (PROcess Field BUS) is a part of the in-ternational IEC 61158 and IEC 61784 standards. Physically, PROFIBUS is either an electrical network based on a shielded, two-conductor cable or an optical network based on a fibre optics cable. PROFIBUS-DP (DP = Decentralised Periphery) is a special application for automating factory production. System A typical PROFIBUS-DP system is made up of: • At least one PLC or industrial PC (master) operat-

ing as a control system. • Various field devices, such as digital or analogue

I/O devices, AC or DC drives, magnetic or pneu-matic valves, frequency converters, starters, oper-ating and indicating devices (slaves).

Data transfer Data exchange within the system is carried out by means of cyclic polling. The master establishes com-munications with one slave at a time and makes data available and/or requests data. The slave being ad-dressed responds immediately to the request for data. Once completed, this procedure is repeated with the other slave devices. This is a continuous cyclic process.

GSD files (device database files) The GSD file is the obligatory ‘ID card’ of each and every PROFIBUS device. It contains the characteristic data of the device, details about its communication capabilities as well as other information, such as diag-nostic values. Weidmüller has made available for downloading all GSD files of the SAI distributors from the SAI Active Universal series – at: http://www.weidmueller.com. For more information, please refer to Chapter 5 (Com-missioning).

1.3. Bluetooth

Bluetooth Bluetooth defines a universal wireless interface in the 2.4 GHz ISM band. No license is required for the 2.4 GHz ISM band. Users are not required to register or pay usage fees. The acronym ISM stands for Industrial Scientific Medi-cal and describes the potential scope of its use. A range between 10 metres to 100 metres is defined because of Bluetooth's minimal transmitting power of a few milliwatts. System A Bluetooth system consists of a maximum of 255 nodes. From these however, only 8 can be simultane-ously connected to each other.

The Weidmüller Bluetooth SAIs are formed from Picon-ets consisting of one master and six slaves. Thirty-two of these Piconets can be operated in parallel. The Bluetooth master, which functions as the PROFIBUS gateways, is simultaneously a slave in the PROFIBUS system. The PROFIBUS master views it as a standard PROFIBUS slave with a modular I/O con-figuration. The Bluetooth gateway can be configured with a GSD file. Protocol The standard Bluetooth profile is used. The communi-cation protocol then uses this. The implementation is based on the CANopen / WIRELESSopen standards.

2.1. Project planning

Planning the bus system The following steps must be taken into consideration when designing an installation: • Location of the machine or facility • Assignment of the signals to the installation to a logical group • Selection of the field devices • Assignment of the signals to the field devices • Determination of where the field devices are to be installed Criteria for determining the correct SAI distributor: Size of the connec-tors

Determine the size of the connectors to suit your application, the design of the sen-sors or according to your personal preferences. Weidmüller offers both M12 and M8 variants for purely digital signals

Number of poles of the I/O connections

Please consider the sensor/actuator cable to be connected; possible options are 3 or 5 poles

Y-piece (twin) Specifically for 5-pole M12 sensor connections, you can feed two cables to a dis-tributor input by means of a Y-piece.

Inputs / outputs Weidmüller has a variety of SAI distributors on offer such as a variant with 16 digital inputs, with mixed digital inputs/outputs as well as an analogue/digital version (for more information please refer to Chapter 4 (Connecting SAIs).

Shielding Shielding by means of metal connectors is necessary for bus connections. We rec-ommend the same approach for analogue signals to restrict the susceptibility to interference.

Signals Please consider if you wish to transmit analogue or digital signals.

Table 1: Determining the SAI distributor

2.2. Power supply

Example calculation to determine voltage drop in the lines:

Star or line topology wiring can be used to feed the power supply. Only modules without digital outputs are suitable for line topology wiring.

Power is supplied via the plug in connection AUX IN; power is fed to the next module via the module connec-tion AUX OUT.

Caution

The maximum current supplied to the first module must not exceed 2.5 A per power supply pin. The supply voltage at the last module must not fall below 18 V DC.

When determining the maximum number of modules in series you should take into con-sideration the total current of all modules and the voltage drop in the line.

Figure 4: Voltage drop

Voltage drop to module 1 (line resistance x length of line L1 x 2) x current con-sumption (Module 1 + Module 2+ Module 3) Voltage drop from module 1 to module 2 (line resistance x length of line L2 x 2) x current con-sumption

Voltage drop in the lines: (Line resistance) x (total length of line) x (2)

(Module 2 + Module 3) Voltage drop from module 2 to module 3 Total current of the modules: (line resistance x length of line L3 x 2) x current con-sumption

3.1. Mounting dimensions and position

Note

Please observe that a given distance to the adjacent module may be required when using custom assembly and angled connec-tors.

An SAI distributor can be mounted in any position. There are no restrictions placed with regard to their position when being mounted: vertical, horizontal, on their side, or overhead. However, to ensure that the LEDs can be seen, we recommend that – where possi-ble – the modules are not mounted on their side or overhead. Our SAIs can be mounted side by side. The mounting dimensions of our SAI distributors are 210 x 54 mm.

You can find details about the mounting di-mensions in Appendix B: Drilling Templates.

Figure 5: Mounting dimensions for the SAI Active Uni-

versal


3.2. Mounting SAI distributors

Mounting To mount the SAI distributor, select a firm and level surface. Pre-drill the bore holes (for more information, please refer to Appendix B: Drilling Template). Hold the distributor above the bore holes and fix it in positions with screws. Please use a spring washer if the SAI distributor is to be used in an environment where the loads are subject to increased shock and vibration. Please refer to Figure 5: Mounting dimensions for the SAI Active Universal. PROFIBUS guidelines Please observe the PROFIBUS guidelines: Installation Guideline for PROFIBUS-DP/FMS.

Figure 6: Mounting an SAI distributor

DANGER

Isolate (de-energize) the system before con-necting the power-supply connector or insert-ing or removing jumpers.

Torque We recommend the following torques: M8 connector: 0.6 Nm M8 protective cap: 0.4 Nm M12 connector: 0.8 Nm M12 protective cap: 0.8 Nm Screw for window: 0.5 Nm

Functional earth (FE) The functional earth is the earthing (ground) of equip-ment to its surroundings. Contrary to the protective earth (PE) the FE does not primarily serve to protect equipment or persons, but instead serves to discharge electrostatic charges and shield connections.

Caution

Electromagnetic pulses affect cabling and the distributor during operations. Flawed signals and false data can result. Do not use a PE conductor for the FE con-nection.

SAI distributors from the SAI Active Universal series are equipped with an FE connection integrated at the mounting hole in the bus/power section. Use this con-nection and fix the distributor directly to a conductive surface or attach a short, low impedance FE cable to the fixing screw by means of a cable lug. Please refer to Figure 6: Mounting an SAI distributor.

Figure 7: Functional earth ‘FE’ connection

Required accessories / DIN components 2 socket-head cap screws, M4 x 30 We recommend cylinder head studs with hexagon-socket or Torx type. Tools Allen key or Torx screwdriver appropriate to the screw you choose. For more information, please refer to Ap-pendix A: Overview of items - Recommended tools.

3.3. Marking and labelling

Twenty transparent markers in a MultiCard frame are included in the range of supply of the SAI distributors. These allow you to individually mark the I/O connections as well as the distributor. Either two normal or one longer marker can be used to specifically mark the distributor. Please refer to the following graphic Figure 8: Attaching the markers. Weidmüller has various printers and plotters available to achieve professional printing results. For advice and a demon-stration, please contact your Weidmüller partner.

To achieve rapid, manual on-site marking results, we recommend our STI-S fibre pen (please refer to Appendix A: Overview of items).

Figure 8: Attaching markers and tags

Note

Please note that you should not stick marker tags on top of one another. Nor should you use coloured markers since they can cover up the LEDs below them.

3.4. Setting the PROFIBUS address

PROFIBUS address The PROFIBUS address is used to determine at which address your SAI distributor will be identified on PROFIBUS-DP. Setting Set the PROFIBUS-DP address for the SAI distributor in the settings section of the distributor. Use a flat-bladed screwdriver to adjust the rotary switch. Tools Use a 2.5-mm flat-bladed screwdriver (please refer to Appendix A: Overview of items). Address / hexadecimal code Please note that PROFIBUS-DP allows a maximum of 126 possible addresses. The addresses 1 to 125 are defined. Please note that the address 126 is used for configuration purposes and the addresses 01 and 02 are retained for the PROFIBUS master. The distributor address is set in hexadecimal code by means of two rotary coding switches. To do so, you will have to con-vert the decimal address to hexadecimal or, for the sake of simplicity, you could make use of the table below.

Example: To set the PROFIBUS-DP address 93, turn the left-hand rotary coding switch to position 5 and the right-hand rotary coding switch to position D.

Note

Each address must be allocated only once on PROFIBUS-DP. The PROFIBUS address that you set must match the PROFIBUS address for this distributor set in the project configuration software. If you alter a PROFIBUS address during operations you will have to disconnect the power supply and then restart the system to enable the master to recognise the change.

Table 2: Code conversion decimal < - > hexadecimal

1073380000/1.3/08.09 Weidmüller t 15


- Master:

The rotary switches are used for setting the Profibus address network. The switches are used for setting the Bluetooth network. Set the rotary switch to position 1. The sliding switch is used to define which networks are to be set. Slide the switch to position 1 in order to set the first 16 networks. Slide the switch to position ON in order to set the next 16 networks (17 – 31). - Slave:

The first rotary switch is used to set the slave's node address. The second rotary switch is used for setting the Bluetooth network. Set the rotary switch to position 1. The connection will be established within about 40 seconds. Tools Use a 2.5-mm flat-bladed screwdriver (please refer to Appendix A: Overview of items). Address / hexadecimal code

The distributor address is set in hexadecimal code by means of two (or three) rotary coding switches. To do so, you will have to convert the decimal address to hexadecimal or, for the sake of simplicity, you could make use of Table 2.

16 Weidmüller t 1073380000/1.3/08.09


3.5. Setting the Bluetooth address

Note

Each Bluetooth address can occur only once with a Piconet. The defined network address must be identical with a network. If you alter a Bluetooth address during op-erations you will have to disconnect the power supply and then restart the system to enable the master to recognise the change.

Bluetooth address The Bluetooth address is used to determine at which address your SAI distributor will be identified from the Bluetooth master. The Bluetooth address consists of a node address and a network address. Slave address The slave address defines the location (address) of the participant within the Piconet. Each slave address can occur only once within a Piconet. The Bluetooth gate-way always uses the node address 0; this cannot be adjusted. Network address The network address defines the Piconet which the SAI should be connected to. The settings on the SAI and the Piconet gateway must be identical.

Setting Set the address for the SAI distributor in the settings section of the distributor. Use a flat-bladed screwdriver to adjust the rotary switch.

1073380000/1.3/08.09 Weidmüller t 17


3.6. Dismounting the SAI

DANGER

Never plug in or pull out a power connector or jumpers when the system is live (ener-gized). Turn off the power supply to the sys-tem first.

Caution

No immediate damage will occur to the de-vice if you dismount an SAI distributor when the system is operating. However, the disruption to PROFIBUS will place the rest of the plant in an uncontrolled state. This can lead to indirect damage. Disconnect the power to the system before you mount or take off the distributor.

Dismounting • Turn off the power supply to the system. • Disconnect the connections to the power supply on

the SAI distributor. • Disconnect the PROFIBUS connections on the SAI

distributor. • Disconnect the I/O connections. • Dismount the distributor by undoing the mounting

screws. Tools Use an Allen key or Torx screwdriver appropriate to the screw you choose. For more information, please refer to Appendix A: Overview of items - Recommended tools.

4.1. PROFIBUS / RS-485

PROFIBUS is a universal, open, digital communication system providing solutions for a wide spectrum of appli-cations – first and foremost in production and process automation. PROFIBUS is a suitable solution for fast, time-critical applications, as well as for complex com-munications tasks. PROFIBUS communication is an-chored in the international standards IEC 61158 and IEC 61784.61158. The criteria for its use and planning are defined in the openly accessible guidelines available from the PROFIBUS User’s Organisation (PUO). These guide-lines fulfil the demands on the part of the users for multi-vendor and open solutions. That guarantees the communication between devices of differing manufac-tures – without having to make prior adjustments. Additional information is available under www.profibus.com.

Table 3: Contact assignment (pin out) of the PROFIBUS connector

Select the bus cable as cable type A in accordance with IEC 61158. The PROFIBUS connection is made via a 5-pole M12 male connector (Bus IN) and a 5-pole M12 female connector (Bus OUT). Both connections are B-coded. Use the "Bus In" connection to feed in signals and "Bus Out" to route these forward. In the SAI, male and female connectors are conduc-tively connected. That enables the PROFIBUS to be routed from SAI to SAI without the need for spur lines.

Note

It is possible to connect the SAI distributors by means of a spur line for low transmission rates up to 1500 Kbit/s. The total length of the spur line must not exceed 6.6 meters. The spur lines should be kept as short as possible. Avoid the use of spur lines for baud rates greater than 1500 Kbit/s.

PROFIBUS addressing Two rotary switches in the address section of the SAI are used to make the necessary bus address settings. The setting is made in hexadecimal code from 00H to 7EH which corresponds to the decimal values from 0 to 126 (see also Appendix C: Converting decimal to hexa-decimal, page 82). Note It is only possible to set the bus address in the address section of the SAI. Any alterations made to the bus address during operations will be recognised and adopted following the next reset (turning off the power supply). The factory-set default bus address on the SAI is 03.

A table is available in the Appendix C to aid conversion of decimal to hexadecimal ad-dresses.

Setting the Bluetooth gateway address The Bluetooth side of the gateway only needs to have a network address specified. The node address at the gateway is always 0 and cannot be changed. The rotary switch NA and jumper J1 are used to establish the address and SAI address range. The table on the right lists the exact functioning of the net-selection switch (NA). Network addresses from 1 to 31 can be assigned.

5.1. Device Data Base Files (GSD) and bitmap files

GSD files (device database files) GSD files are the electronic data sheets of a device that provide a PROFIBUS master with straightforward in-formation about the characteristics of the PROFIBUS DP field device. The information in these files includes: • The supported transmission rates • The length of the input and output data to be ex-

changed • The meaning of the diagnostics parameters and

the application parameters • The field device type • The supported services

The files are provided with the file extension gsd. The following data is valid for the SAI-AU BT GW 12DI PROFIBUS gateway: ID number: 0A75 GSD file (device database file): WIAU0A75.GSD Version: 14

Bitmap files Symbols are made available for display in the hardware configurator. The name of the bitmap file for normal operations is WIAU_BTN.DIB. The name of the bitmap file for diagnostics is WIAU_BTS.DIB.

WIAU_BTN.DIB WIAU_BTS.DIB

Figure 37: Bitmaps for hardware configurator

How the GSD and bitmap files are used and their memory location depends on the con-figuration tool being used. Hardware configuration is explained below, based on an ex-ample using the programming software Simatic® Step7. ® Registered trademark of Siemens AG

1073380000/1.3/08.09 Weidmüller t 51


5.2. Copy the GSD files to the local directory

The GSD files are available for downloading free of charge from Weidmüller’s homepage, http://www.weidmueller.com/54266/Downloads/Software/SAI-Active-Data/cw_index.aspx?newsid= The memory location of the GSD files is determined by the installation routine of the Step7 programme. Usually, this is below the installation directory \Step7\S7DATA\GSD. The necessary bitmap files are copied into the \Step7\S7DATA\NSBMP directory.

52 Weidmüller t 1073380000/1.3/08.09


5.3. Install the GSD files in Step7

Open the proper project in the programme Step7 and select the hardware configuration.

Figure 38: Installing the GSD file: step 1

Note

Close all Step7 applications before continu-ing with the following commands.

Select the command Extras > Update Catalogue to update the contents of the catalogue in the hardware configurator.

Figure 39: Installing the GSD file: step 2

1073380000/1.3/08.09 Weidmüller t 53


When selecting the PROFIBUS-DB device, look under PROFIBUS-DP => Additional field devices => Gateway => Bluetooth-Gateway for the Weidmüller Bluetooth SAI modules.

Figure 40: GSD file catalogue

5.4. Adding a BT-GW in the hardware configurator

The hardware configuration with a PROFIBUS DP-enabled central processing unit (CPU 315-2 DP) has been launched and a PROFIBUS DP master system has been defined for this CPU.

You can now add individual devices to the PROFIBUS DP master system. A pop-up window opens in which the PROFIBUS address can be assigned. You can set parameters on the Parameter tabbed page.

Note

Assign each PROFIBUS address only once.

Figure 41: Hardware configurator


The gateway which has been inserted now has slots available for modules. Up to seven modules can be added to these slots. A maximum of six devices can be connected with Bluetooth. The seventh device or the first device depicts 12 digital gateway inputs (digital input: DI). On PROFIBUS, these 12 DIs are connected via a 16-DI identifier, since only a byte-by-byte assignment is pos-sible. An excerpt from a gateway is shown in the figure below. In this example, all available module types are listed once.

Note

According to the definition, the Gateway IOs must occupy the first slot. No "holes" are allowed in the slot list. The SAIs must be listed in the proper order according to their identifiers (node numbers).

Figure 42: The gateway slot list

These modules are stored in the GSD file. They are assigned the application parameters in this file. There are a total of four modules in the selection list: the Gateway-IOs 12DI, a SAI 16DI, a SAI 16DI/8DO and a SAI 4AI/2AO/4DI.

Note

The Universal Module is a Step7 attachment and cannot be deleted.

Figure 43: Module types

56 Weidmüller t 1073380000/1.3/08.09


5.5. Assigning the input and output addresses

Each PROFIBUS DP device is already automatically assigned an address, with which data is exchanged with the PLC programme.

You can accept or alter these addresses. The quickest method is to double-click the address bar of the se-lected device. Then it is possible to select the starting address.

Activates the DESINA function Bits 0 to 7 set the DESINA diagnostics of the connec-tions 1 to 8. The DESINA diagnostics functionality is activated if the corresponding bit is set to 1. If the DESINA diagnostic functionality is activated, the con-nection at pin 4 acts as a DESINA diagnostics input. The connection at pin 2 is then the switch input to be monitored.

Bits 0 to 7 1 = DESINA functionality ON Bits 0 to 7 0 = DESINA functionality OFF

Table 39: DESINA parameters

Defines the function of the connection point as input or output The input of bit 0 to bit 7 sets the functionality of pin 2 of the connections 1 to 8 as well as 1 to 16 of the M8 connection. Setting this bit to 1 activates the output. Set to this status, short-circuits to earth and +24 V DC will be recognised and reported in the diagnostics. Bits 0 to 7 1= connection pin 2 is INPUT Bits 0 to 7 0= connection pin 2 is OUTPUT

Table 40: Reversal of input and output

Defines how the outputs react when there is a bus malfunction. The entries for Bit 0 to Bit 7 determine for each output if it enters a safe status or if it retains the last status. If this bit is set to 1, the output retains the last status that prevailed before the bus error occurred. The safe status is defined in byte 5 Bits 0 to 7 1 = OUTPUT goes into safe

status Bits 0 to 7 0 = OUTPUT retains most recent

status

Table 41: Behaviour when bus malfunction occurs

Defines the safe status of outputs The entries for Bit 0 to Bit 7 determine for each output if it is ON or OFF when in the safe status. Bits 0 to 7 1 = OUTPUT switches ON Bits 0 to 7 0 = OUTPUT switches OFF

Configuration of the analogue inputs The four analogue inputs are set with two bits respec-tively. The first bit defines the type of measurement as voltage or current measurement; the second bit sets the meas-urement range in accordance with the selected meas-urement.

Bit 0 0 = analogue input 0 VOLTAGE measurement 1 = analogue input 0 CURRENT measurement

Bit 1 0 = analogue input 0 measurement range 0 to 10 V or 0 to 20 mA 1 = analogue input 0 measurement range –10 V to +10 V or 4 to 20 mA







Table 43: Configuration of the analogue inputs

Configuration of the analogue outputs The type of signals of the two analogue outputs (as current or voltage output) is determined by the selection of the connection pin and the configuration. The meas-urement range is configured in accordance with the selected output type.

Bit 0 0 = analogue output 0 VOLTAGE measure-ment 1 = analogue output 0 CURRENT measure-ment

Bit 1 0 = analogue output 0 measurement range 0 to 10 V or 0 to 20 mA 1 = analogue output 0 measurement range –10 V to +10 V or 4 to 20 mA

Manufacturer diagnostics information The manufacturer’s diagnostics information can be composed of one or more bytes. The manufacturer determines the amount and their content. For SAI modules, these include various diagnostic information depending on the type of module; a part of this information has to be activated by parameterisation.

An overview of the diagnostic bytes is given below; these bytes are counted after the standard diagnostics information byte 6.

The gateway is structured modularly with up to seven modules. Seven universal modules are established in the diagnostics data so that each module can be added to each gateway position.

6.3. Evaluating diagnostic data in Step7

Whereas the data for inputs and outputs can be ex-changed and processed directly in Step7 with PROFIBUS via the input and output image, diagnostic data must be read into the application programme with an SFC.

Diagnostics data (slave diagnostics) of a DP slave is read with the SFC 13 "DPNRM_DG".

Figure 48: Diagnostics function block

Input variables:

REQ = 1: Request to read

LADDR: Planned diagnostics address of the DP slave; this can be read in the hardware con-figurator.

Note: The address must be entered in hexadecimal, for example, the diagnostic address 1022 (3FEH) means: LADDR: = W#16#3FE

Output variables:

RET_VAL RET_VAL contains the length of the actual transmitted data.

If an error occurs when the function is being processed, the return value contains an error code.

RECORD Target range for the read diagnostic data.

The minimum length of the data record to be read or the target range is 6.

BUSY = 1 The read operation has not been completed

Table 53: Diagnostics function block

In the example above, 10 bytes following the flag byte M 120.0 are reserved as target range of the diagnostics data for an SAI-AU M12 PB 16DI. These are divided up as follows:

Standard diagnostics information

MB 120 Byte 0 Station status 1



MB 123 Byte 3 Diag. master address

MB 124 Byte 4 Ident number (high byte)

MB 125 Byte 5 Ident number (low byte)

Accuracy

Bit accuracy is a measure of the exactness of digital measurement and calculation operations. With an accu-racy of 8 bit, for example, 1 byte corresponds to an accu-racy of 1/(2^8) = 1/256 or 0.390625% steps. This is par-ticularly important when converting from an analogue signal to a digital value if the measurement value of a sensor (temperature, pressure or similar) is to undergo further digital processing.

AI

Please see Analogue input

Analogue input

Analogue input detects analogue signals as voltage sig-nals from 0 to 10 V or as current signals from 0 to 20 mA or 4 to 20 mA; resolution is generally 10 or 12 bit, 16 bit representation.

Analogue output

Analogue input control variable as analogue signal; volt-age signals from 0 to 10 V or -10 V to +10 V or as current signals from 0 to 20 mA or 4 to 20 mA; resolution is gen-erally 10 or 12 bit, representation 16 bit representation.

AO

Configuration

Please see Hardware configuration.

Configuration menu

This is used to enter and configure the hardware of a controller system. Please also see Hardware configuration.

Connector

A plug-in connector connects lines carrying electrical power or signals. The standards regulate the form and the contact assignment of the connector and the corre-sponding mating connector. They also define the electri-cal signals to be transmitted.

DATA A

Data from PROFIBUS is transmitted via a two-core, shielded twisted-pair cable with RS485 characteristics (differential signal transmission). The two wires are des-ignated as DATA A (green wire) and DATA B (red wire).

DATA B

Data from PROFIBUS is transmitted via a two-core, shielded twisted-pair cable with RS485 characteristics (differential signal transmission). The two wires are des-ignated as DATA A (green wire) and DATA B (red wire).

DESINA

Please see Diagnostics input DESINA

DI

Please see Digital input.

Diagnostic telegram

Diagnostic telegrams indicate the status of the PROFIBUS-DP slave. A diagnostic telegram is composed of six bytes of standard diagnostics information as well as the manufacturer’s diagnostics information. The number of bytes required for the manufacturer’s diagnostics var-ies from module to module.

Diagnostics data

Diagnostics data is transmitted in a diagnostics telegram. This information is differentiated between standard diag-nostics information (6 bytes) and vendor diagnostics in-formation, the length of which depends on the vendor.

Diagnostics input DESINA

DESINA is an abbreviation for DistributEd and Standard-ised INstAllation technology for machine tools and manu-facturing systems. DESINA describes the specification for

standardising the electric, hydraulic and pneumatic instal-lation of automated machine tools and manufacturing systems. DESINA diagnostics input supplies diagnostic information in addition to the digital input signal. See also http://www.desina.de.

Frequency converter

A frequency converter generates an alternating current of a certain frequency from an alternating current of a differ-ent frequency and may also alter the voltage; it makes it possible to adjust rotational speeds. In particular for three-phase motors, frequency converters are an eco-nomic form of control.

Functional earth

The functional earth serves to discharge compensating and interference currents in order to guarantee EMC characteristics. According to VDE 0100, the functional earth is not the same as the protective earth; it is forbid-den to use it as the protective earth.

GSD file (Device Data Base File)

A GSD file (Device Data Base File) contains a description of all of the DP slave-specific characteristics.

1073380000/1.3/08.09 Weidmüller t 91

The format of GSD files is defined in the standard IEC 61784-1:2002 Ed1 CP 3/1.

Hardware configuration

All devices and parameters of a control system are de-fined in a hardware configuration.

Hardware configurator

Special software that is normally manufacturer-specific and used for creating and downloading a hardware con-figuration.

Hexadecimal code

Numeric code that represents information from 1 digit, 4 bit, decimal numbers 0 to 15 using digits 0 to 9 together in conjunction with the letters A to F.

High byte

The high byte is the most-significant byte of a term con-sisting of two or more bytes, for example, a software ver-sion number. Please see Low byte.

J1

Designation for a special jumper field used to link supply voltages.

Jumpers

Jumpers are used to configure electronic sub-assemblies or set operating parameters that are carried out either rarely or only once during initial commissioning proce-dures. The jumper is usually made of a small metal plate and a plastic housing. It is plugged into two pins which results in an electrical contact being created via the metal plates. Generally, that results in the function of the hardware com-ponent being activated, deactivated or configured.

Low byte

Least-significant byte of a term consisting of two or more bytes, for example, a software version number. Please see High byte.

M12

Metric thread with a thread diameter of 12 mm.

M12 socket (female connector)

A socket with cavities containing contacts for creating an electrical connection. Sockets are also referred to as fe-male connectors. The mating partner of a socket is re-ferred to as the plug or male connector. The socket outlet can be described as a special form of socket.

M8

Metric thread with a thread diameter of 8 mm.

Output addresses

External signals in a PLC are exchanged via digital or analogue inputs or outputs. These are controlled by the PLC programme via the addresses. The addresses can be a combination of station address, module address and connection address. It sometimes possible that the ad-dresses can only be accessed byte for byte or word for word.

Output interval

Please see sampling period.

Parameter

Parameters describe the technical characteristics of tech-nical devices. Weidmüller SAI parameters serve to acti-vate the DESINA diagnostic input, to define plug-in con-nectors as inputs or outputs, as well as define the ana-logue measurement ranges as a current or voltage input.

Parameterisation

Term used to describe assigning parameters with a parameterisation or programming tool.

PE

Please see Protective earth.

Peripheral devices

These are devices outside of a central processing unit; with Fieldbus systems, this also applies to all devices in the Fieldbus.

PLC

PLC is the acronym for Programmable Logic Controller

Plug and Play

Sometimes written as Plug 'n' Play or Plug & Play; it de-scribes the characteristics of modern, mostly peripheral devices that are immediately available for use without having to first install a programme.

Polling

The generally recognised term for "to poll" or query. The poll function is an operating mode of Fieldbus devices in a Fieldbus system.

Power supply

Electrical loads require a voltage supply to provide the power. In control systems, the supply voltage used is 24 VDC. Please see voltage range.

Power supply

Voltage with which the device is supplied. The power supply in automation engineering is usually 18 to 24 VDC.

PROFIBUS

(PROcess FIeld BUS) is a part of the international stan-dards IEC 61158 and IEC 61784. Physically, PROFIBUS is either an electrical network based on a shielded, two-

1073380000/1.3/08.09 Weidmüller t 93

conductor cable or an optical network based on a fibre optics cable.

PROFIBUS guidelines

Vendor-independent compatibility is guaranteed by tech-nical guidelines to ensure implementation of PROFIBUS technology. The technical guidelines are published and distributed centrally by the PROFIBUS User Organisation (PUO) to underline the fact that these are effectively a standard. Diverse PROFIBUS guidelines are available, for example: the "Optical transfer technology for PROFIBUS".

PROFIBUS slave

PROFIBUS slaves exchange data cyclically with a PROFIBUS master. In addition, parameterization, con-figuration and, in the case of a malfunction, diagnostic data is transmitted. Typical PROFIBUS slaves include connection terminals, repeaters, gateways, communica-tion terminals, valve blocks and others.

PROFIBUS User Organisation

More than 260 vendors and users of the standardised communication system PROFIBUS have come together in the registered association PROFIBUS User Organisa-tion (PUO) to jointly support further technical improve-ments and establish the use of the technology interna-tionally. The PROFIBUS User Organisation is a regis-tered association. Membership is open to any company or research facility anywhere in the world.

PROFIBUS-DP

This is a special application for automating factory pro-duction. DP = Decentralised Periphery

PROFIBUS-DP address

With the PROFIBUS address you determine at which address your SAI distributor will be identified on PROFIBUS-DP.

PROFIBUS-FMS

This is utilised for the universal, object-oriented, cyclic and acyclic exchange of data at a medium speed. FMS is particularly suitable for exchanging data between intelli-gent slaves such as PCs and PLCs. PROFIBUS-DP and PROFIBUS-PA are special variants. FMS = Fieldbus Message Specification

PROFIBUS-Master

PROFIBUS-DP differentiates between Class 1 and Class 2 masters. The Class 2 master is utilised for parameteri-

zation of PROFIBUS slaves by means of software; it is mainly used to set the PROFIBUS address. As well as exchanging data with the slave, the Class 1 master sup-plies the PROFIBUS slave with configuration and pa-rameter data.

PROFIBUS-PA

This is used to control field devices by means of a proc-ess control system in the processing industry. This variant of PROFIBUS is used in hazardous areas (Ex-Zone 0 & 1). Low currents only are used so that no sparks flash-over in the case of a malfunction; it uses a slower data transmission rate. PA= Process Automation

Protective earth

Protective earth conductors are often used in electrical equipment and cable lines. This is also known as the pro-tective lead, earth, earth connection or PE (protective earth). The task of the protective earth conductor in electrical systems is to protect human beings from dangerous touch voltages as well as to protect the system from damage. The PE conductor is fitted in such a manner that there is an electrical connection between the outer metal housing of the electrical equipment (for example lamps, fridges, motors). Should a fault occur and the electrical supply voltage comes into contact with the exterior of a piece of electrical equipment, the short-circuit to ground via the PE conduc-tor should ensure that the voltage between the housing of the respective electrical equipment and the ground (with which humans and animals are generally in contact) is reduced to a harmless level. At the same time, the high short-circuit currents trip the fuse. That ensures that the electrical equipment with the fault is disconnected extremely quickly from the supply voltage. German regulations stipulate that the PE conductor must be identifiable by the colour combination green/yellow.

Repeater

Repeaters are necessary in order to create a CAN net-work with more than 32 stations or establish a larger net-work extension. The repeater represents the beginning of a new segment in which the maximum number of stations can be used or the maximum extension is defined.

Rotary coding switch

94 Weidmüller t 1073380000/1.3/08.09


Requiring a minimum of space, rotary coding switches are used to make settings. These settings are usually coded in decimal or hexadecimal formats.

RS-485

As a so-called differential voltage interface, the RS-485 interface operates with +5V (high) and 0V (low) by which the non-inverted signal is transmitted via one wire and the inverted (or negative) signal via the other wire. As distor-tions have the same effect on both signals, the difference between both signals remains (virtually) the same and can be used for evaluation purposes. An RS-485 connection constitutes a serial data transmis-sion, which means the bits are transmitted one after the other on a line.

SAI

The acronym SAI stands for Sensor – Actuator – Inter-face. It is a compact-designed distributor or collector of signal lines.

SAI distributor

Please see SAI.

Sampling period

The sampling period determines in which time interval an analogue input is converted. The sampling period for the SAI-AU AI/AO/DI can be set between 5 ms and 250 ms.

Segment

The PROFIBUS network consists of one or more seg-ments. The maximum extension of a segment depends on the baud rate being used. Up to 32 PROFIBUS sta-tions can be connected in each segment.

Settings section

Range on the SAI in which the configuration of the hard-ware is carried out; for example, the module address.

Shielding

Shielding is necessary to protect cables from radiated noise disturbances.

Simatic® Step7

STEP 7 is the current programming software used for the Simatic S7 PLC family of products from Siemens; this is a family of controls for PLC based automation systems. In accordance with IEC 61131-3, the basic version of STEP 7 includes the programming languages: • CFS - Continuous Function Chart

• LD – Ladder Diagram • STL – Statement List

Slave

Please see PROFIBUS slave.

Temperature coefficient

The temperature coefficient is a relative change to a physical variable resulting from a change in temperature of 1 K (Kelvin).

Torx screwdriver

Torx is an improvement to the cross-head screw and hexagon-socket (Allen) as a tool receiving socket, for example in counter-sunk screws. The profile is similar to a six-pointed star with rounded off points and corners – more or less a wave form. The com-pany Camcar belongs to the Textron Group and is the inventor and patent holder. In the meantime, the Torx patent has run out and the hexalobular internal drive fea-ture has been incorporated in international standards.

T-piece

A t-piece is used to provide uninterrupted feed of the supply voltage and the Fieldbus. T-pieces are connected straight onto the consumer load and interconnected with the supply voltage or Fieldbus by means of male and female connectors.

Transmission rate

Please see Baud rate.

Voltage range

The voltage range of the 24 VDC supply voltage is 18 VDC to 30 VDC.

X1

Rotary switch for setting the CAN address, in hexadeci-mal format, low byte from 01H to 0FH.

X10

Rotary switch for setting the CAN address, in hexadeci-mal format, high byte from 10H to F0H.

Y-Plugs

Y-plugs separate two digital signals, inputs or outputs applied to an M12 connector in two digital signals.
