5.1 GENERAL
Read this section thoroughly before making connections. Installation personnel should be
qualified technicians.
The controller provides communications capability for both ICN (peer-to-peer) and Modbus
networks, permitting the controller to communicate on two different networks simultaneously.
Port 1 uses built-in communication drivers and is configured for Modbus RS-232
communications. Port 2 requires a modular driver and is configured for Instrument
Communication Network (ICN) peer-to-peer communications. Communications connections
are made to the terminals shown in Figure 5-1. The communications network diagrams in
this section show connections for both the built-in and modular communications circuits.
The RS-232 communications port is in the bottom of the front panel. This port permits
connection of a portable computer for data base configuration using Visual Application
Designer software.
