Description
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.
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.
Signal
PI synchronized indicates that the protection-interface connection is
synchronized with the opposite end.
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.
