Example of an External Power Failure

Example of external voltage monitoring:
DOK-CONTRL-MTS-R0*.2G2-PR01-EN-P
The transistor output modules RMA02.2-16-DC024-200 and RMA02.2-32-
DC024-050 are provided with a 24-V voltage monitoring unit. One
monitoring bit on a bit strip of 1-word width is made available per module.
A "1" on bit 16 indicates that one or more 24-V supply voltages are
missing (the bit number corresponds to the slot number). This status
information is permanently updated; it is overwritten by an error message.

Slot
Explanation
"0" = the 24-V voltage applied to the output
modules is "OK". If the 24-V voltage fails, this
bit and the corresponding bit in the low word for
the slot concerned are set to "1".
