2. MODBUS Communication Protocol

FIO2 series support Modbus protocol in both ASCII / RTU versions. The Modicon MODBUS specification is designed to transfer data in 1-bit (coil) or 16-bit (register) blocks. This protocol has not been designed to deal with data, such as floating point numbers, which require a minimum of 32-bit blocks. For this reason, every manufacturer of flow computer equipment which deals with this type of data must decide in which way the protocol should be extended. As a result, many different implementations exist for the transfer of 32-bit floating point data.

FIO2 series support the following commands:

Command 3 read multiple registers

Command 6 write single register

Command 16 write multiple registers

All data stored within FIO2 is represented by one or more 16-bit registers. There may be registers which contain a collection of bits. In this case, a 16-bit register is still used rather than provide individual bit (coil) access.

2.1 Data structure FIO2 respond to more than one Modbus address through a single communication port. Each slave has a consecutive Modbus address beyond the base address of the device.

The base address must be set directly on the device, and is set as 0 by default. If the device address is left unchanged, the “Master Table” database can be managed querying slave 1, the “Acquisition” database at slave 2, and so on.

Each database is identified by a Type attribute. If more than one database of that type is present, each one will be presented as a different slave (e.g. data logger 1 – 3).

Database Type MODBUS offset

master table 1 +1

acquisition 2 +2

data logger 1 3 +3

data logger 2 3 +4

data logger 3 3 +5

statistics logger 4 3 +6

alarm logger 4 +7

event logger 5 +8

flow computer 7 +9

Some slave like data loggers are organized in setup section and data section. In the Setup section are configured all the working luetooth ; the data section represents a window over the logged data (if present).

The data table starts at address 0 (0x00), while the setup section starts at address 200 (0xC8).

The format of the data in the Modbus database are the following:

DATA FORMAT BYTES

Uint 2

Int 2

Ulong 4

Float 4 (Ref. IEEE 754)

Char(n) n

Since Modicon did not define 32-bit transfers, the order of transmission for (16-bit) words of a 32-bit value is also not defined. FIO2 implementation uses the first 16 bit word as the most significant.

2.2 Modbus exception codes

Some code, not included in the standard Modbus protocol, are been used to highlight application related error:

0xFC : communication channel busy. This error is displayed when during a remote communication the device is read locally.

0xFD: access denied. This error is displayed when accessing the Modbus register without executing the login procedure.

The Acquisition Slave allows the configuration of FIO analog and digital inputs and digital outputs and the reading of current values.

All Fio inputs and outputs are identified by a progressive Id from 1 to 12. Each type of I/O is described by a different set of information.

PRESSURE SENSORS

Register 202-208 – Pressure Pd: id=1, sensor type ABS or GAUGE, full range and current value (bar, absolute or relative depending on sensor type), Alarm status

Register 209-215 – Pressure Pu1: id=2, sensor type ABS or GAUGE, full range and current value (bar, absolute or relative depending on sensor type), Alarm status

Register 216-222 – Pressure Pu2: id=3, sensor type NOT-PRESENT, ABS or GAUGE, full range and current value (bar, absolute or relative depending on sensor type), Alarm status

Register 223-229 – Pressure Ptank: id=4, sensor type NOT-PRESENT, ABS or GAUGE, full range and current value (bar, absolute or relative depending on sensor type), Alarm status

Register 230-232 – Pressure Patm: id=5, current value (bar, absolute)

TEMPERATURE SENSOR

Register 233-240 – Gas temperature: id=6, zero-scale, full-scale and current value (Kelvin), Alarm status

DISPLACEMENT SENSORS

Register 241-244 – Displacement 1: id=7, Sensor type (NOT PRESENT, PRESENT), current value (%)

Register 245-248 – Displacement 2: id=8, Sensor type (NOT PRESENT, PRESENT), current value (%)

COUNTER INPUTS

Register 247-254 – Counter 1: id=9, Pulse weight, input type (BF/HF), Pulse Type (Gross/net flow), KTVO pressure selector

Register 255-260 – Counter 2: id=10, Pulse weight, input type (BF only), Pulse Type (Gross/net flow), KTVO pressure selector

DIGITAL INPUT

Register 261-262 – Digital input: id=11, current value (0000xxxx, bit 0..3)

DIGITAL OUTPUT

Register 263-270 – Digital output: id=12, repetition mode (pulse,remote, diagnostics), prescaler, repeated volume id, remote command status/length/duration, repeated diagnostics bit mask

SENSOR CALIBRATION

Registers 271-274 are used for sensor calibration, as follows:

- register 271-272: calibration value

- register 273: id of the sensor under calibration

- register 274: calibration command / command result

The calibration procedure is as follows:

- start calibration command for a sensor id

- apply a first external measure value

- set first calibration point value

- apply a second external measure value

- set second calibration point value

- end calibration save/abandon

Pressure and temperature calibration always needs two measure values, corresponding to the first and second calibration points. Displacement calibration needs a value only when the Set low scale command is used. Zero-scale and full-scale commands implicitly assumes 0% and 100% value respectively.

All commands of a calibration sequence must refer the same sensor id submitted on Start calibration command. A different sensor id in a

command causes a command failure and the calibration procedure is terminated.

Register 274 assumes the following result values after the command execution:

10 – command executed correctly

11 – command unknown

12 – command rejected for some reason (e.g.: different sensor id than that under calibration)

Register 276 – Counter 1: Number of Pulses / m3 for counter 1 in HF configuration

R 258 1 Uint Record size (registers)

R 1000 – 65000

1 LOGREC Data area

The Logger Slave is divided in two area: the data area (registers 1000 to 65000), where a sliding window of all the memory assigned to this slave can be used to download the logged data, and a configuration area (registers 200 to 257) where the user can define the log rate, the log type, the log strategy, the memory dimension and the parameters to log.

For each slave of this type a maximum of 40 different parameters can be inserted in the logger; when different log rate or log type are requested, a different logger slave should be used. When Statistical logging type is selected, a maximum of 24 different parameters are available.

Configuration Area

The register 202 gives information about the Logger slave status.

Register 203 is used as a cursor to slide the windows of the data area on the memory. It can be set beetwen 0 and the maximum dimension of the logger (register 217). To read the first record of a table, the value 0 should be written in the register 203, then the data area should be read. In this area you will find the selected record first, then the subsequent records till the maximum dimension of 90 registers.

The register 204 gives information about the number of records filled from the beginning of the Start Log command.

Register 205 is used to start or stop the logger (for the complete command list see table CMD_TAB).

In the registers 206 to 213 the user can write the log table name (not relevant for the Explorer).

Register 214 contains the log rate of the parameters of this slave. The log rate could be assigned beetwen 1 and 43200 seconds (12 hours). The value –1 defines a period of one day (24 hours), and the value –2 a period of one month. The log rate must be a multiple of 30 seconds, due to the minimum sample calculation interval.

Registers 215 defines the log type, “mean” or “statistical”. In the “mean” case, each sample in the log record consists of a single 2-registers value, which represents:

- for measure and flow (float) values, the mean of the 30 seconds samples in the period

- for volumes, the difference between the value at the end of the period and the value at the beginning of the period

- for totalizers, the value at the end of the period

In the “statistics” case, each record is composed by 4 2-registers values, representing the mean, the maximum, the minimum value and the standard deviation in the period, always sampling at 30 seconds intervals. The statistics log type is meaningful only for measure and flow values. Volumes and totalizers cannot be included in a statistical logger.

Registers 216 defines the log strategy:

- for “circular” orrespo, at the end of the maximum capacity newer records automatically override older records

- for “stop when full” strategy, at the end of the maximum capacity newer record are simply discarded

Register 217 contain the maximum number of records in the table. The whole logging interval then is (maximum number of records * log rate).

Registers 218 to 257 defines the structure of each record of the Logger. The value of these registers must be selected from the Identifiers listed in table VAR_TAB. The unused entries must be set to 0 and the record terminates at the first entry set to 0. Logger record structure is defined by the number and type of signal included and by the log type. In case of statistical logging type, the maximum number of entries is limited to 15, due to the maximum record size.

Register 258 reports the record size (number of registers for each record.

Data Area

The data area is a sliding window on the log database. The record selection is based on the value of the cursor position register (address 203). The area contains the sequence of logged records, starting from the selected one (newer) to the last (older) logged record, or to the end of the data area (to the upper multiple of the record size, wich fits in the data area dimension).

Each record is composed as in LOGREC table.The record size depends on the number of selected parameters and on the Logging Type (Mean or statistics).

When reading the area, the register address must be 0 or a multiple of the register size of the log record (plus the area base offset). Also the requested size must be a multiple of the log record size.

6. Modbus Slave 06: Statistics Database

The Statistics database slave has the same register structure than the logger database, but all configuration values are fixed in order to store a predefined set of variables, in statistical mode, for a cyclic 30 days interval of hour samples. Only the command register can be written to start and stop the recording, and the cursor position to select the record to read.

Register 202 shows the number of total alarm records available for logging

Register 203 configures the strategy used for management of the buffer; if circular is selected, when the buffer is full the logger will proceed overwriting older entries; when selected stop when full, the logger will stop as soon as all the available records have been written

Register 204 is used as command register

Register 205 selects the starting record to show as first entry in the data area

Register 206 reports the number of records logged

Register 207 specifies how many records to delete, starting from the older entry

Registers 208 – 217 are used to configure the CCID security check: if this field is empty (all values set to 0x00) no check is executed; if it contains a valid value, it is compared to the CCID reported from the SIM every time the modem is used, and, if there is no orrespondence, it forbids the utilization of the modem

Registers 218 – 219 are used to configure the PIN used to access the SIM (if necessary)

Registers 220 – 227 specify the SIM phone number; this field is not used by the application

Register 228 reports the quality of GSM signal, from 0 (no service) to 30 (highest quality)

Register 229 defines a timeout in seconds, starting from the time of reception of the last valid message, after which the communication (local or remote) ends. If this timeout expires, it will be necessary to perform the login procedure again

Register 230 defines the maximum total duration, in seconds, of a communication; is this timeout expires, a remote connection is shut down, while a local connection requires to perform a login again

Register 231 defines the minimum time interval between modem restarts (0 = disabled)

Register 232 defines the strategy used for periodic calls:

periodic strategy determines the execution of calls separated by a fixed interval of time (register 238); the delay gets calculated from the starting time of 00:00

strategy by calendar allows the execution af a single call in a day, specifying in which days of the month the call must be executed (register 234)

Register 233 defines the strategy used to cycle through the list of call destinations, in case of incomplete communication. If the call to the first destination fails, the device can be configured to retry over the same destination or step down the list to the next one

sequential strategy repeat the call to the actual destination for as many times as specified in register 240, after that it steps to the next destination in the list

alternate strategy cycles through all the destination, one try for every destination. Once it reaches the end of the list, it either stops or starts again from the first entry, depending on the number of retries configured (register 240)

Registers 234 – 235 are used only if strategy by calendar is selected: they specify in which days of the month the call must be done, one bit for every day, starting with bit 0 for day 1, ending with bit 30 for day 31

Registers 236 – 237 specify the time of the day (hours:minutes) at which the call must be executed; if strategy by calendar is selected, it refers to the only daily call; if periodic strategy is selected, it refers to the time at which start the first periodic call.

Register 238 is used only if periodic strategy is selected, and specify the calling period

Register 239 specifies the delay, in seconds, between two retries; retries are executed only in case of a incomplete communication

Register 240 specifies the number of retries to execute in case of incomplete communication

Registers 241 – 328 specify the list of destinations of outgoing calls and UDP packets. Every destination can be a phone number (e.g. +393337864001, or 0422533421), or a IP address, followed by port number (e.g. 192.123.45.22:32400); every UDP packet destination must be an IP number + UDP port (e.g. 192.123.45.22:32400)

Register 329 defines the strategy used to send alarms through SMS/email:

sequential strategy sends a SMS or an email for every alarm to the first entry in the list of SMS/email destinations; the successive behaviour depends on the configuration of every destination: if the destination has been configured with notification flag active, the device will wait for a configurable time (register 330) to receive an acknowledge SMS, and, in case of successful reception, will remove the alarm from the buffer; if no acknowledge SMS is received before the time specified, it steps to he next entry in the list. If the notification flag is off, or the destination is an email address, the alarm is considered acknowledged and automatically removed from the buffer

send to all strategy sends an SMS or an email to every valid destination of the list; when a destination requiring the notification is encountered, a return SMS will be waited as for the Sequential strategy. In case, during this waiting time, no SMS is received, it will be sent an SMS to all the phone numbers in the list. After 3 cycles, alarm will be considered “Aknowledge” anyway.

Register 330 specifies the maximum waiting time for an acknowledge SMS

Registers 331 – 332 specify the time of the day at which turn the modem on, to be able to receive incoming calls and SMS.

Register 333 specifies the interval between successive activations of the modem. If value 0 is used, but registers 331 – 332 contains a valid time of the day, only one activation of the modem will be performed for every day. If using a different value, it will cause the device to turn on the modem by the period specified, starting from the time configuredin registers 331 – 332 and ending at 23:59

Register 334 specifies the duration of the activations of the modem

Registers 335 – 418 specify the list of destinations of alarm SMS/emails. Every destination can be a phone number (e.g. +393337864001) or an email address, and has an associated notification flag which specifies if the device must wait for an acknowledge from this destination. Notification flags are used only for SMS destinations.

Registers 419 – 506 specify the list of allowed phone numbers / IP addresses. If this list is empty, no checks on the caller are performed. If this list contains valid phone numbers and/or IP addresses, the device accepts data communications and SMS only from callers/senders present in the list

Registers 507 – 558 specify the configuration parameters for GPRS connection

Register 559 specifies the activation of GPRS server: if the server is ON, the device will answer to incoming TCP connection

Register 560 specifies the TCP port used by GPRS server, if active

Register 561 specifies the refresh interval of GPRS server: if the value is not 0, the device will send an UDP packet to every IP entry in the list of outgoing calls at the interval specified. The UDP packet contains, between other data, the serial number of the device and is useful to associate the device to its IP address (if it’s unknown by the destination, as in case of dynamical assigned IP addresses)

Registers 562 – 633 specify the configuration parameters for outgoing emails (SMTP server)

Registers 634 – 637 specify the configuration of the 485 serial port used for master/slave FIO connections

Registers 638 – 642 specify the configuration of the 485 serial port used for slave only FIO connections

Registers 643 – 645 reports the hardware setup of the device: number of analog, digital and counter inputs

Registers 646 – 795 specify the configuration of six analog alarm managers (REC_ALL_AI), two input counter alarm managers (REC_ALL_CNT), and one digital input alarm manager, as described il the following tables.

Registers 796 – 797 specify the set of alarm conditions, other than analog, counter and digital ones, enabled to add an alarm record in the alarm list and also a sms generation. Each of 32 bit “1” value enables the corresponding alarm code (see ALARM_ENABLE table below)

Registers 798 – 803 specify the enabling of password protection on read or modification accesses for every communication channel. If set to 1, the corresponding channel will request authentication before allowing the selected operation (read / modification).

Registers 1000 – 9999: Data Area

The data area is a window on the alarm database. The area contains the sequence of stored alarm records, starting from the newer to the older stored record. Each record is composed as in REC_ALARM table. When reading the area, the register address must be 0 or a multiple of the register size of the alarm record (plus the area base offset). Also the requested size must be a multiple of the alarm record size.
