Cause : Telegram failure at GSST3 comes when the receipt of the first valid protocol, no further telegrams have been received within the time period set in parameter P807.
- USS telegram failure to G-SST3 (active from the first receipt of a valid protocol in all operating states)
Possible fault causes:
- Cable break
- Error in USS master
- Interruption in connecting cable
- EMC interference on connecting cable
- P807 is set too low
when P800 = 4 or 5: Peer-to-peer telegram failure at G-SST3 (active in operating states of ≤ o6)
Cause : Telegram failure at GSST3 when P800 = 2:
USS telegram failure to G-SST3
(active from the first receipt of a valid protocol in all operating states)
After the receipt of the first valid protocol, no further telegrams have been received within the time period set in parameter P807.
