Ethernet rear ports supervision
RCHLCCH or / and SCHLCCH are used for supervision. RCHLCCH block supervises redundant
channels and SCHLCCH block supervises status of Ethernet ports.
RCHLCCH outputs signals
– CHLIV
– REDCHLIV Status of redundant Ethernet channel LAN B. When redundant mode is set to
– LNKLIV
– REDLNKLIV Link status of redundant port LAN B
1V LG 5 000 07 E
Status of redundant Ethernet channel LAN A. When redundant mode is set to
HSR or PRP mode, value is True if the protection relay is receiving redundancy
supervision frames. Otherwise value is False.
HSR or PRP mode, value is True if the protection relay is receiving redun-
dancy supervision frames. Otherwise value is False.
