The Comm Gateway Module includes two Ethernet ports which provide

TCP/IP communications capabilities. 

The supported industrial protocols are:

• Modbus TCP/IP: Modbus over Ethernet is available for

connection to HMI’s, unit control systems, or other plant

automation equipment. The module can only be

configured as a server and supports configurable

Modbus addresses within the 40000 address range.

• Ethernet Global Data (EGD): EGD is a GE protocol used

on Mark VI and Mark Vie controllers and by GE

Programmable Automation Controllers and certain 3rd

party automation equipment. Version 3.04 and

backward compatibility with previous versions is supported.

•  PROFINET (Process Field Network): is an open Industrial

Ethernet communication protocol used for real-time data

exchange between controllers and devices in industrial automation. 

The CGW operates as a PROFINET device, protocol specification V2.45 

(including backwards compatibility), Conformance Class B, Real Time Class 1.

The CGW PROFINET implementation supports a point-to-point (direct) network

connection from the CGW to the PLC.
