COMMUNICATIONS CONNECTIONS
5.1 GENERAL
Read this section thoroughly before making connections. Installation personnel should be
qualified technicians.
The controller provides communications capability for both ICN and Modbus networks. Two
serial communication ports are available permitting the controller to communicate on two
different networks simultaneously. Port 1 can use either built-in or modular communication
drivers. Port 2 requires a modular driver. Communications connections are made to the
terminals shown in Figures 5-1a (Model C) and 5-b (Models A & B). The communications
network diagrams in this section show connections for both the built-in and modular
communications circuits.
In addition to the network communications capability, the controller provides an RS-232
communications port in the bottom of the front panel. This port permits connection of a
portable computer for data base configuration using the PC configuration software.
