FANUC Robotics America GFK-1541B User Manual

 The Ethernet Interface enables Series 90 PLCs to communicate with other Series 90 PLCs, with
with GE Fanuc PLC programming software, and with applications developed using the SRTP
protocol, such as CIMPLICITY® HMI.

 The Ethernet Interfaces described in this manual have “client/server” capability.  As a “client” the
Interfaces can initiate communications with other Series 90 PLCs containing Ethernet Interfaces.
This is done from the PLC ladder program using the COMMREQ function.  As a “server” the
Interfaces respond to requests from other devices such as PLC programming software, a Host
computer running an SRTP  application, or another Series 90 PLC acting as a “client”.  No PLC
programming is required for server operation.

The diagram below represents a basic Ethernet Communications system.
