The 5 VDC output voltage of the power supply module (for the CPU, I/O and the interfaces)
are monitored by the power supply monitoring module F 7131 checking undervoltage, over-
voltage or failure.
In case of a faulty power supply module the operating system of the CPU informs the user pro-
gram via a system variable.
In case of a 5 VDC system power failure a lithium battery on the central module buffers the
hardware clock and sRAM on the central module.
The sRAM memory of the coprocessor module is buffered via two lithium batteries on the pow-
er supply monitoring module F 7131.
