Chapter 1. Modbus Communications
1.1 Introduction
Your flowmeter hardware and software ( GC3E.MBS) have been modified to provide improved MODBUS communications. The MODBUS option card provides an RS485 interface with a host system, while the main circuit board continues to support RS232 communications for use with a PC running PanaView™ software.
Note: PanaView™ does not support Modbus.
To properly set up the instrument, use this addendum along with the standard flowmeter User’s Manual. This document shows how to install the MODBUS option card and how to program the modified flowmeter to access this special feature.
When equipped with the optional MODBUS output card, the flow transmitter can send flow data and diagnostic information to a flow computer (or SCADA) serially, using a Gould-type RTU protocol. In this case, only the
MODBUS function command, 3 (read multiple registers), 6 (write multiple registers) is valid. The format for the data exchange is as follows:
• The send command (initiated by the host flow computer or controller) comes in the form:
[time delimiter]<Addr><3><First Register MSB>
<First Register LSB><Register Count MSB>
<Register Count LSB><CRC Low><CRC High>[time delimiter]
• The response (initiated by the host flow computer or controller) comes in the form:
[time delimiter]<Addr><3><Byte count><Data.........>
<CRC Low><CRC High>[time delimiter]
The format for the returned data types is as follows:
• Integer (16 bit Integer) <MSB><LSB>
1 Register - 16 bit integer
• Integer (32 bit IntegerI) <MSB><LSB><LSB><LSB>
2 Registers - 32 bit long integer
• Floating Point (FP) <EXP><MAN><MAN><MAN>
2 Registers - 32 bit IEEE floating point number

Chapter 1. Modbus Communications
1.2 Installing the MODBUS Option Card
IMPORTANT: The installation information presented here supersedes the information in the standard flowmeter User’s
Manual.
The modified flowmeter uses the RS485 standard for MODBUS communications. This standard allows up to 32 nodes
(drivers and receivers) on one multidrop network, at distances up to 4,000 ft (1,200 m). To connect the instrument(s) to the host system, GE Sensing recommends using a 24-gauge (24 AWG) twisted-pair cable with a characteristic impedance of 120 ohms and a 120-ohm termination at each end of the communications line.
The MODBUS option card must be plugged into either slot 5 or slot 6 of the flowmeter. On the option card, pin 1 is the
[TMT-] inverting or negative connection and pin 2 is the [TMT+] non-inverting or positive connection. To link the flowmeter to the control system, connect the two wires of the twisted-pair cable from these terminals to the corresponding terminals at the control system.
Note: If two MODBUS option cards are installed in the flowmeter, only the card in slot 5 is activated.
1.3 Setting Up MODBUS Communications
To set up MODBUS communications, enter the User Program as described in your Programming Manual. Then, refer
to the menu map in Figure 2 on page 22 and complete the following steps:
Note: Any time the following settings are changed, the flowmeter must be rebooted to load the new settings into the option card.

To request specific parameters from the flowmeter using MODBUS, the control system must enter the appropriate register number. Only registers 1 through 90 are available for MODBUS communications, while registers 508 through
512 are used by the flowmeter to store the MODBUS parameters. For details, see:
Table 2 on page 5 for a 1-Channel gas flowmeter (GC868, GF868, GM868, GN868, GS868, XGM878, XGS878)
Table 3 on page 6 for a 2-Channel gas flowmeter (GC868, GF868, GM868, GN868, GS868, XGM878, XGS878)
Table 4 on page 9 for a 1-Channel liquid flowmeter (DF868, XMT868i)
Table 5 on page 11 for a 2-Channel liquid flowmeter (DF868)
Table 6 on page 14 for a Sentinel flowmeter.
Refer to
Notes on page 8, page 13, or page 16 for information about the numerical references.
Note: Depending on the type of flowmeter being programmed, some MODBUS register numbers may have zero readings. If this is the case, those register types are not available for that flowmeter.
Note: If you request Ch2 or AVE data from a 1-Channel meter, the values will all be zero.

* The complete floating point value is constructed by combining readings from the first register with a second register. An eight Hex digits number will represent the IEEE-754 hexadecimal floating point value. 32-bit Hexadecimal Representation
To Decimal Floating-Point conversion can be performed if needed.
Example: Reg 4 reading is 44d7, Reg 5 reading is 4000, Volumetric is 44d74000, which corresponds to 1722.
**The complete Long integer value is constructed by combining readings from the first register with the second register.
Eight Hex digits will represent the Long interger value.
Example: Reg 2 is 0019, Reg 3 is ED30, Hexadecimal Velocity is 0019ED30, which corresponds to 1699120 decimal.
Taking into account that Velocity has 2 decimal places (from the map), it corresponds to a value of 16991.20.

1.4.2 Notes for a Liquid Flowmeter:
1. Clear Totalizers: Write 1 to Reg 1 to clear Channel 1 and Channel 2 totalizers.
2. Error Value: see table in DF868 manual for error codes
3. Average: average of channel 1 and channel 2 if both channels out of error, channel 1 value if channel 2 is in error, channel 2 value if channel 1 is in error, zero if both channels are in error.
4. Average Error Status:
0 = both in error
1 = chan 2 in error,
2 = chan 1 in error,
3 = both ok
5. MODBUS baud rate:
5 = 2400, 6 = 4800, 7 = 9600
6. MODBUS parity:
0 = none, 1 = odd, 2 = even
7. MODBUS stop bits:
1 = 1 stop bit, 2 = 2 stop bits
8. General:
Registers are written if corresponding functions are actuated by the user. Registers for unactuated functions are initialized to zero at startup.
9. Error Code:
Highest number (single or combination of errors) listed, without an “E”. Error codes should be explained in the user’s manual.

1.4.3 Notes for a Sentinel Flowmeter
The
Sentinel Flowmeter, when equipped with the optional Modbus output card, can transmit flow data and diagnostic information to a flow computer or SCADA, serially, using a Gould-type RTU protocol. For security and audit-trail purposes, the unit must be programmed through the PanaView interface. This means that only the Modbus function command 3 (read multiple registers), is valid.
Communication parameters: 9600, n, 8, 1
The format for the data exchange is as follows:
• The send command (initiated by host flow computer or controller) is of the form:
<time delimiter> <Addr> <3> <First Register MSB>
<First Register LSB> <Register Count MSB>
<Register Count LSB> <CRC Low> <CRC High> <time delimiter>
• The response (initiated by host flow computer or controller) is of the form:
[time delimiter] <Addr> <3> <Byte count> < Data ……… >
<CRC Low> <CRC High> <time delimiter>
Table 6 on page 14 is the data map for the
IGM878 and Sentinel. The refresh rate indicates how often the central controller updates the memory map, available using the ModBus port. The most time-critical information is stored at the top of the register. This limits how deep the user has to go into the resister stack to gather the real-time information.
All values are IEEE format MSB first (big-endian).
The
Sentinel LCT and Sentinel LNG support digital communications using the MODBUS/RTU protocol, with 2-wire
RS-485 or 3-wire RS-232C as the physical layer. Data rate can be specified from 4800 to 19,200 bits per second (bps), with selectable parity.
Note: Regarding meter status, each bit field indicates the error number from LSB corresponding to E1, and from
MSB corresponding to E32.
Note: Writing any non-zero value will clear the totals (unless they are locked using TOT LOCK/KEY LOCK switches on the front panel - per MID requirements).
Note: Writing to COMP will clear all channels.
Note: Modbus Registers for the Sentinel LCT or Sentinel LNG Flowmeter, Table 7 on page 17, has some fields with a grey background. These are currently not supported and will return a value of –1.0.

Note: To install an option card, consult the user’s manual(s) which apply to your instrument.
Communications Options User’s Guide 23
Chapter 2. Modbus Over Ethernet Communications 1
2.2 Setup
The default IP address in setting up the Ethernet option card is Dynamic (DHCP). If it has to be changed to a static IP address, the instrument must first be connected to the DHCP network.
Note: The following are setup procedure examples.
2.2.1 Finding the Assigned IP Address
Example:
Find the IP address of a module with Media Access Control (MAC) address 00409d25da0b.
1. Open a DOS command prompt. Go to the directory containing the executable ruiping.exe.
2. Type ruiping -e and hit
Enter.
Note: Once the module containing the MAC address has been found, it will be displayed along with the assigned IP address (see Figure 10). In this example the assigned address is 3.112.161.79.
3. Stop the process by hitting the
Esc key.

5.4 Tips for Improving Wireless Data Communications
A suitable installation site should locate the antenna in a transmission path as unobstructed as possible; in the direction of the associated router.
When a wireless transducer is linked to a router, a yellow LED on the WI-FI option board remains on. Received Signal Strength Indication (RSSI) is an important indicator of wireless link quality. The higher the RSSI, the stronger the performance a wireless system can provide. Signal Strength is calculated by a wireless transceiver and can be viewed on Administration-System Information -
WI-FI LAN - Active Settings of the device home page (see Figure 37 on page 51).
If constant interference is present in a particular frequency zone, it might be necessary to change the operational channel in the WI-FI network. If interference problems persist, try reducing the length of data streams by reading less registers in one request. Groups of short data streams have a better chance of getting through in the presence of interference than do long streams.

For a GF868 flowmeter, the option card connector is mounted on the card, and the HART device leads should go to pins 1 and 2 of this connector. As for other option cards installed in the same meter as the HART option card, the
HART device will not recognize any option card installed in Slots 3-5 and it will only recognize option cards installed in Slots 1-2 if they are Analog Input, Analog Output, or RTD option cards.
For XGM868, XGS868 and XMT868 flowmeters, the HART device connections must be made to pins 1 and 2 of the
12-pin terminal block J2 on the terminal board. Therefore, you must make sure that any option card installed in Slot 1 does not use these terminals.
Note: Refer to your User’s Manual for a complete description of the available Slot 1 option cards and their terminal usage.
8.3 Flowmeter Software Setup
GE Panametrics flowmeters that are shipped with a factory-installed HART option card require no special setup procedures by the user. The meter automatically configures itself for HART communication on startup. However, for field-installation of a HART option card, the card must be configured in the factory test menu before it will be recognized by the meter. Thereafter, the initialization will be automatic on startup. Contact the factory for specific instructions.
In addition to setting up the HART option card so that it is recognized by the meter, the analog output of the option card may be configured using any of the following methods (if available):
• the flowmeter keypad
• Instrument Data Manager (IDM™) software
• PanaView™ graphical user interface software
• the HART device
To configure your HART option card analog output using any of the first three methods, follow the instructions in the appropriate User’s Manual. During configuration, the choice of parameter must be limited to those listed in Table 10 on page 69. To use the HART device for configuration of the analog output, refer to the instructions that came with that device.
Note: Because HART communication is unreliable at analog outputs below 4 mA, the flowmeter automatically
changes a HART option card analog output configuration of 0-20 mA or OFF to a 4-20 mA configuration upon startup. Check to make sure that the analog output configuration is set to 4-20mA. If for some reason, it has not been automatically changed, set it to 4-20mA from the front panel.

Chapter 8. HART Communications
8.3 Flowmeter Software Setup (cont.)
Some flowmeter parameters can only be read by the HART device during startup. Therefore, it is recommended that both the flowmeter and the HART device be rebooted after any reprogramming of the HART option card analog output.
Failure to do so may result in erroneous information or a communication failure between the flowmeter and the HART device.

NOTE: “acf” is reported as “normal cubic feet” in HART. Also, “Mega” units (i.e. mgal/day, mcf/day, etc.) are reported as standard units x 10^6 in HART. For example, 1 mgal is 1x10^6 gal in HART.
8.4 Using the HART Interface
The HART communications option card installed in GE Panametrics flowmeters has been successfully tested with the
Rosemount 275 Hand-Held Communicator and the Rosemount AMS Computer-Based Communications
Software. Although some flowmeter functions may be performed using the HART device, many other functions (i.e. data logging, site file uploading, site file downloading, printing, etc.) must still be programmed by the methods described in the flowmeter User’s Manual. This is because the HART protocol was developed for use with simple transmitters and it cannot handle the multitude of sophisticated functions built into the GE Panametrics flowmeters.
8.4.1 Unit Types
Due to limitations of the HART protocol, only those unit types listed in Table 10 are acceptable. If a meter parameter is set to any other measurement units, the HART device displays an “Unknown Enumerator, Can not resolve” error message and may terminate communications entirely. In some cases, both the Hart device and the flowmeter may have to be rebooted to clear the error. To address this potential problem, the flowmeter has been programmed to force all measurement units to HART compliant units if a HART option card is detected upon startup.
Communications Options User’s Guide 69
Chapter 8. HART Communications
8.4.2 HART Functions
After HART communications has been properly set up, the following flowmeter functions may be accessed using the
HART device:
• static temperature and static pressure
Note: To view the static temperature or pressure for a channel using the HART device, the fixed value for that
parameter must be assigned to that channel at the flowmeter. See your User’s Manual for instructions.
• tracking windows (XMT868 only)
• minimum and maximum soundspeed (XMT868 only)
•
2-path error handling
• velocity averaging response time
• static density
• error handling
• mA error level (if selected)
• clear totals
Note: Refer to your User’s Manual for a complete description of each of the above functions.
When information is viewed through the HART device, the input variable always appears as either Channel 1
Temperature or Channel 1 Pressure. Although these inputs are not necessarily assigned to Channel 1, the HART protocol labels all inputs as channel-specific. For example, a Slot 1 analog input that is programmed at the meter as a temperature input assigned to Channel 1, Channel 2, Both, or Neither is always reported by the HART device as a
Channel 1 Temperature input.
Note: Inputs cannot be assigned using the HART device. Also, any input assigned as “Special” is always reported as a Channel 1 Temperature input by the HART device
In addition to the functions listed on the previous page, the following procedures may be performed through the HART device:
• calibration and setup of the HART option card analog output
• calibration and some programming of analog inputs, analog outputs, and RTD inputs on option cards installed in
Slots 0 (all), 1 (all), and 2 (GF868 only)
• viewing some of the flowmeter’s diagnostic parameters
8.5 List of Programmable Variables
For convenient reference, all of the programmable variables for the four flowmeter models are listed in Table 11 on page 71.
