This section gives an overview of the Serial Communications Boards and the
Serial Communications Unit.
Serial Communications Boards are Inner Boards for the CS-series PLCs. One
Board can be installed in the Inner Board slot of a CPU Unit. Two serial ports
are provided for connecting host computers, Programmable Terminals (PTs),
general-purpose external devices, and Programming Devices (excluding Pro-
gramming Consoles). This makes it possible to easily increase the number of
serial ports for a CS-series PLC.
