Chapter 1. Modbus Communications

Communications Options User’s Guide

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, Panemetrics 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 21 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.

IMPORTANT:

The serial port settings of the flowmeter must match those of the MODBUS control system.

The available RS232 baud rates are 300, 600, 1200, 2400, 4800, 9600, and 19200.
