This programmable controller is another central part of each control system based on the PLC 5 series. It connects local, extended, and remote I/O modules on various communication interfaces into one control system. There are four built-in ports available for this controller. The ports are marked as channel 1A, channel 1B, channel 2A, and channel 2B.
