Communication Modules - IDEC MICROSmart FC6A Series User Manual

Communication Modules

The communication modules include the serial communications module that communicate with peripheral devices using RS-232C
or RS-485 communications.
The communication modules are equipped with two serial ports, and RS-232C or RS-485 can be selected and used for each port.
These modules support the maintenance communication function, user communication function, data link communication, and
Modbus communication function.
Use the communication modules by connecting them to the CPU module. For details on the maximum number of communication
modules that can be connected and slots to install those modules, see "Maximum Number of Modules and Slots to Install" on page
2-139. To use a communication module, it must be configured in the Module Configuration Editor. For detailed configuration
methods, see "Module Configuration Editor" on page 12-1. For details on communication settings, see Chapter 3 "Communication
Settings" in the "FC6A Series MICROSmart Communication Manual".
Note: Communication modules cannot be connected to the expansion interface remote slave module.
