Connecting Communication Ports
Communications ports 1 and 2 on the PPC-2010 Processor
module may be used to communicate with an operator interface
terminal, a computer running AnaWin3, LogicPro, or third-
party software, or any device capable of acting as a host using
the Modbus RTU protocol.
PPC controllers always act as servers or slaves. The computer
or other host device must act as the client or master.
Communication Ports
Both communication ports support RS-232 and RS-485 signals.
A 4-position, 4-conductor telephone handset connector is
provided for RS-232 communications and an RJ12 connector is
provided for RS-485 communications. Only one of these
connectors may be used. Both ports are optically isolated.
