Limit-value for relay switching operations
This is where the total number of permissible relay switching operations is set.
If the limit-value for relay switching operations (C121) is higher than this Limit-
value, error message 0001 is displayed immediately and the relay is de-
energized.
If "0" is set, the function is inactive.
