Communications Card
Either the DeviceNet (see Appendix G: DeviceNet Communications) or the
EIA-232/EIA-485 communications card is supported in Slot C. The EIA-232/
EIA-485 card provides one serial port with one of the following two serial
port interfaces:
➤ Port 4A, an isolated EIA-485 serial port interface
➤ Port 4C, nonisolated EIA-232 serial port interface, supporting the
+5 Vdc interface
Select either EIA-232 or EIA-485 functionality using the Port 4 Setting
COMM Interface. Table 2.3 shows the port number, interface, and type of
connector for the two protocols.
The communications card supports all of the following protocols:
➤ Modbus RTU Slave
➤ SEL ASCII and Compressed ASCII
➤ SEL Fast Meter
➤ SEL Fast Operate
➤ SEL Fast SER
