Chapter 8 Gigabit Ethernet (GbE) Interface Overview and Operation

The Ethernet Interface provides TCP/IP communications with other controllers and with
computers running the TCP/IP version of the programming software. These communications
use the GE SRTP and Modbus TCP protocols over a four-layer TCP/IP (Internet) stack.
The Ethernet Interface provides SRTP server and Modbus TCP client/server capability. As a
client, the Interface can initiate communications with other controllers that contain Ethernet
Interfaces. This is done from the controller logic program using the COMMREQ function. As a
server, the Ethernet Interface responds to requests from devices such as the programming
software, a Host computer running an SRTP or Modbus TCP application, or another
controller acting as a client.
The initial releases do not support SRTP client channel, or Ethernet Global Data protocols.
