Hatanın Anlamı

Alarm: PB/PN sign-of-life synchronism not reached

Olası nedenler

• The bus is in the data exchange state and clock synchronous operation has been selected using the parameterizing telegram
• Synchronization with the master sign-of-life (STW2.12 ..
• STW2.15) could not be completed because the sign-of-life is changing differently to how it was configured in the Tmapc time grid.

Çözüm ve Güvenli İlk Kontroller

1. ensure that the master correctly increments the sign-of-life in the master application clock cycle Tmapc.
2. correct the interconnection of the master sign-of-life (p2045).

Güvenlik: Enerjiyi kesmeden pano içi işlem yapmayın; emin değilseniz yetkili teknisyene danışın.
