The MFX_4 EDI is a gateway between theMFX_4 modules [CANopen] and a Local AreaNetwork [TCP/IP].

The MFX_4 OPC Server is a PC–program[MS Windows–based] that can run on the samePC as the Terminal Automation system [TAS].It offers complete access to all process dataof the MFX_4. The TAS can read and write totables on the OPC Server with no need todirectly interface to the MFX_4.

This industry standard field communicationis used by a wide variety of instrumentationvendors and guarantees flexibility whenadjusting TAS and SCADA systems to thefield instruments.[See OPC–chapter page 16–17]

[MFX_4]

The MFX_4 system communicates to SCADA and Terminal Automationsystems [TAS] via TCP/IP on a Local Area Network [LAN].

The SCADA or Automation System does not need to know the proprietarycommunication protocols of the MFX_4. It interfaces with the OPC Serveron the LAN.

It can thus read and write data in the tables of the OPC–Server which canbe installed on the same machine as the automation system, or can beaccessed via the LAN from another machine.[See page 18: „Communication between MFX_4 and Terminal Automation“]

Alternatively, the MFX_4 can communicate with the SCADA or AutomationSystem in a more traditional manner via RS232 or RS 485 serialcommunication.

The MFX_4 modules communicate via the fieldbus CANopen. This ultra fastand highly secured bus system has been field proven for many years and iswidely used in industrial areas where high speed data exchange is required[i.e. the automotive industry].

The CANopen controllers are integrated into any MFX_4 module.

The field instruments connect directly into the MFX_4 Controller.

The MFX_4 design allows for optimum integration of field I/Os into thesystem: i.e. densitometer frequency signals can be directly connected withoutneed for an extra converter.

Flexible Modular Design:Configuration examples

For simple installations, all modules are installed on the load rack. There is no automation system installed and theoperation is semi–automatic using only the MFX_4 Terminal.

Example 1 : All modules on the load rack

The MFX_4 Compact is used together with two MFX_4 Controllers.The Compact, like the Controllers, can operate up to two meter runs.The driver uses the HMI of the Compact for all meter runs on theloading bay.

In this installation, an automation system [TAS] has been added.The communication between the MFX_4 modules and the auto-mation system runs via an EDI. The EDI converts the CANopen datato TCP/IP for use on an Ethernet LAN.

Attached to the LAN, there is an OPC Server for the MFX_4 systeminstalled. The automation system TAS communicates via OPC withthe MFX_4. It has no direct connection to the field. If the TAS doesnot support OPC technology, it can directly communicate peer topeer via TCP/IP or via serial interface RS 232 and/or RS 485 withthe MFX_4.

In installations where it is preferable to operate in different places,more than one MFX_4 Terminal can be connected to the samemetering positions:

I.e., in the period of conversion from top– to bottom loading, therecan be a requirement for combined load racks that are able toalternatively load top and bottom loading trucks.

On such load racks, the MFX_4’s modular design allows to installone Terminal on the top and another Terminal on the bottom of theload rack.

Scalability

The same MFX_4 can be used for low–cost, simple applicationsas for complex, high–tech solutions.

The smallest system requires a single Controller for the controlof up to two metering points.

No matter how complex the application, the same modules of theMFX_4 System cover the requirement. This allows for scalability togrow and expand to ever more complex installations.

In Aircraft Refuelling applications, the MFX_4 is installed onthe refueller or dispenser truck. Together with the Controller, one[Ex]–Terminal is located in the refuelling zone of the truck.

Another non–[Ex]Terminal is located in the driver’s cabin, togetherwith standard W–LAN communication. This allows the truck fleetmanagement system to send orders to the Terminal in the cabin.

Also, the transaction data can be sent via W–LAN to a cental systemfor Leakage Detection or further data processing.

The MFX_4 System can be connected to an OPC Server via TCP/IPon the LAN. The OPC Server is a program that runs on a PC, eitherseparate or on the same PC as the Automation System.

The OPC Server makes all data from the MFX_4 Flow Computeravailable for other systems [like Terminal Automation or SCADASystems] to use. The data is easily accessible to an OPC Clientthrough read/write tables.

Communication between MFX_4 and OPC Server is at high speedand ful fills all requirements for automation systems.

By accessing the data from tables on the OPC Server, the AutomationSystem does not require proprietary protocol drivers for the field

instruments. Thus, the OPC technology makes communication moretransparent and flexible in case of future changes to the fieldinstrumentation.

OPC is an international standard for field–to–Control Roomcommunication. Many major suppliers of field instrumentation areoffering OPC Servers and Clients for their products.

Fast Availability of all Data of MFX_04in Tables for Read/Write

The OPC structure is similar to that of the Windows Explorer. Withoutknowledge of the field instrument or OPC Server, the SCADA System’sOPC client can access all process data in a hierarchical structure, asshown in the example below.

In this example, the SCADA system reads the Loading Data from theMFX_4 Controller No. 1 [Meter Run No. 1]. All Loading Data is accessibleby Reading/Writing from/to a table within the OPC Server.

The TAS system has written the Preset Values into therelevant OPC table.

The OPC Server transmits the Preset values for the nextload to the MFX_4.

TCP/IP

CANopen

After loading is completed, the MFX_4 transmits the data to theOPC Server where it is made available to the TAS.

The TAS reads this data from the relevant tables.

An example of data exchange between TAS andMFX_4 during loading operations.

The MFX_4communicates directlywith the OPC Server.

The TAS needs no knowledge of the MFX_4’scommunication protocol, since it reads/writesall data in structured tables from the OPC Server.

Communication between MFX_4 andTerminal Automation

The TAS communicates on the LAN with theMFX_4’s OPC Server. The OPC Server can runon the same PC as the TAS.

The OPC Server communicates with the MFX_4using TCP/IP on the LAN.

Advantage:

• TAS does not use proprietary protocol and handshake with MFX_4• all MFX_4 data available on OPC in tables

for read/write• in case of changes of flow computers in the

field, no need for reprogramming of TAScommunication

There are several ways to connect a Terminal Automation System [TAS] with theMFX_4.

Ideally, the TAS communicates on a LAN via the OPC Server with the MFX_4. Butthere are also other possibilities to connect the automation level with the flowcomputer.

TAS peer to peer with OPCTAS peer to peer with MFX_4

The TAS can communicate directly with theMFX_4 using the serial interfaces RS 232 orRS 485. It uses M+F’s MCO1 protocol.

In case of this kind of connection to the MFX_4,the TAS needs to handle handshakecommunication. Also, the TAS needs to beprogrammed in such a way to handle thisproprietary protocol.

The TAS communicates directly with theMFX_4’s OPC Server.

In fact, the OPC Server can run on the samePC as the TAS.

The OPC Server can communicate directlywith the MFX_4 using RS 232 or RS 485.

Metering and Proving Control ManagerMPC Manager

In a typical pipeline metering system, an MFX_4 Controller isdedicated to each meter run as well as the prover. Since the hardwarefunctionality [like dual chronometry] of the MFX_4 Controller isstandard, the same hardware can be used for the meter-dedicatedand prover–dedicated units.

The Start/Stop signals from the prover are directly connected to allMFX_4 Controllers within a system, allowing the controllers to monitorthe pulses from the relevant meters. All other communication isdirected via the CANopen Field Bus to the OPC Server located in theTCP/IP Local Area Network [LAN].

Due to the MFX_4's direct link via TCP/IP communications, all processcontrol functions can be handled on the LAN. This applies to thePipeline Process Manager program and the SCADA system; all existingdata from the field instrumentation can be accessed via the OPCServer for the MFX_4 System.

Dual Chronometry

Dual Chronometry increases the pulse resolution of the flowmeterby dividing each pulse into accurate sub–pulses.

Advantage: Higher accuracy of measurement.
