PLC Main Module

The “Main” or Central Computer if you like is basically a large MCU with 3 x CAN ports and 10 x Modul links. It only need a 5V PSU and can be used stand-alone or combined with other modules to form a larger entity. The central computer controls the entire system of both internal and external units. This board is a big waste land as the modul size dictate the actual size. I might add more to this board later.

The 10 connectors at right are communication links to modules and to an redundant unit if redundancy is required.
