The Critical Control Module (CCM) is the Central Processing Unit of the ProSafe-PLC. It communicates
with ProSafe-COM via M-BUS or M-NET. The CCM module performs the actual control in the
ProSafe-PLC. Through the PLC I/O modules, it retrieves values from the inputs and sends appropriate
signals to the outputs. The MBX module is the intermediate between ProSafe-COM and the M-BUS.
