CHAPTER 4: COMMUNICATIONS

FIGURE 4–1: RS-485 Serial Connections

Note

The EPM4

00 optical port is disabled for units with 2-wire RS485 connections.

4.1.2

RS232 Wiring for Modbus

The wiring for Modbus communications for RS232 is indicated below.

4.1.3

Modbus Commands

The EPM4

00 is capable of acting as a remote slave unit to a Modbus master device via

modem, RS232, RS485, or PLC. Up to 32 EPM4

00 meters (or other RS485 devices) can be

daisy-chained together on a single LAN.

The EPM4

00 communicates at a default baud rate of 19200, with no parity and 1 stop bit.

The default Modbus address is 100. Changes to the default baud rate or address can be
accomplished through the configuration file upload.

The following Modbus commands are supported by the EPM4

00:

• 03: Read R4 type register(s)
• 06: Write single register; address “0” is used as the broadcast address
• 16: Write multiple registers; address “0” is used as the broadcast address

4.1.4

Fixed Modbus Values

The EPM4

00 provides fixed register values indicating the meter's serial number, the

meter's version number, and the Modbus addresses.
