GE Multilin 239 239-RTD-AN-H
The GE Multilin 239 implements a subset of the AEG Modicon Modbus RTU serial
communication standard. Many popular programmable controllers support this
protocol directly with a suitable interface card allowing direct connection of relays.
Although the Modbus protocol is hardware independent, the 239 interface uses a 2
wire RS485 hardware interface. Modbus is a single master multiple slave protocol
suitable for a multi-drop configuration as provided by RS485 hardware. In this
configuration up to 32 slaves can be daisy-chained together on a single
communication channel.
The GE Multilin 239 is always a Modbus slave. It cannot be programmed as a Modbus
master. Computers or PLCs are commonly programmed as masters. The Modbus
protocol exists in two versions: Remote Terminal Unit (RTU, binary) and ASCII. Only the
RTU version is supported by the 239. Monitoring, programming and control functions
are possible using read and write register commands.
The following functions are supported by the 239:
• 03 - Read Setpoints and Actual Values
• 04 - Read Setpoints and Actual Values
• 05 - Execute Operation
• 06 - Store Single Setpoint
• 07 - Read Device Status
• 08 - Loopback Test
• 16 - Store Multiple Setpoints
