1 The Ethernet Interface allows you to directly attach the Series 90-70 PLC to an Ethernet LAN via a user-supplied transceiver and AUI cable, and to communicate with other PLCs, hosts, and other control devices on the network. The Ethernet Interface for the Series 90-70 PLC has “client/server ” capability. As a “cli- ent” it can initiate communications with other Series 90 PLCs containing Ethernet Inter- faces. This is done from the PLC ladder program using the COMMREQ function. As a “server”

1 Note Typically, there will be only one GSM on the network. It will contain configuration information and communications software for all the GEnet stations on the network. The Configuration Editor The Configuration Editor is a menu–driven software package that is part of the GSM. It is used offline to examine and modify configuration parameters for the GE Fanuc Series 90-70 Ethernet Interfaces on your network. These configuration parameters are stored in files on the PC hard disk and subse
