Binary Output Signal
Description
(_:5161:319) Time
delay different
Signal
Time delay different
indicates that the threshold value for asym-
metrical transit times has been exceeded. The setting value results from the
setting value of the parameter
(_:5161:110) Difference Tx and Rx
time
.
(_:5161:320) Time
delay jump
Signal
Time delay jump
indicates that the data transit times changed
abruptly. This is caused by switching the communication path in the communica-
tion network.
(_:5161:321) PI
synchronized
Signal
PI synchronized
indicates that the protection-interface connection is
synchronized with the opposite end.
(_:5161:340) Tele-
gram lost
Signal
Telegram lost
indicates that an expected telegram has failed to arrive
or a faulty telegram has been received.
If you would like to allocate the communications failures or faults to other events,
move the signal
Telegram lost
temporarily into the operational log. Such
events can be switching operations in the primary system or operations on the
components of the communication network.
Note: If the signal is constantly routed, the operational log can overflow. Siemens
recommends routing the signal only for clarification of faults.
Measured Values of the Protection Interface
The protection interface provides the following measured value to diagnose the protection interface commu-
nication:
