Serial communications ports
The controller communicates through a number of serial ports. The CPU module contains two serial ports.
One is an RS 232 connection to a PC and another is dedicated for connection to the operator interface. The
CPU with optional communications features two additional RS 485 serial ports.
The serial port connectors on the CPU module are shown in Figure 23. Table 10 summarizes the
communication link connections to the controller and other reference data for wiring details.
