3.7 PSC-CPU-MON / PSC-CPU-OP-MON
3.7.1 General description
The CPU module is the central control unit of the PROTECT-PSC and is responsi-
ble for the following::
• Executing the user program/FB firmware
• Evaluating and controlling the safe and operational I/O modules
• Monitoring power supply
• Visualising status/error messages of the PROTECT-PSC
The version PSC-CPU-OP-MON has an additional battery enabling the operational
data (e.g. error protocol, data of the PN program, ….) to be maintained also if the
power is switched off (see Chapter 3.7.4 / 3–35).
Operating mode 3
If the PROTECT-PSC is in mode 3, the CPU module acts like a module with 4x2
inputs and 3x2 outputs.
