Blocking of the Operate Indication, No Fault Recording at Pickup
With the Blk. Op. Ind. & Fault Rec. parameter, you define whether a function works as a protection
or a monitoring function. Further, you use this to determine the type and scope of the logging (see following
table)
Parameter Value Description
No
The function works as a protection function. It generates an operate indica-
tion and starts fault recording with pickup. During fault recording, a fault is
created and logged as a fault record in the fault log.
Yes
The function works as a supervision function. The logic runs normally, but
without creating the operate indication. The time-out indication is still
generated and can be processed further if necessary. No fault recording
starts with pickup.
