0 = commissioning phase (for CDC error, no STOP D is
initiated)
1 = commissioning completed (for CDC error, STOP D ini‐
tiated)
If DB18, DBX36.1 was set to 1, for a crosswise data com‐
parison error, instead of an external STOP D, an external
STOP E is transferred to the drive
Net (useful) data:
External PLC input for the SPL
External PLC output for the SPL
Internal PLC input for the SPL
Internal PLC output for the SPL
Marker for SPL
Signal differences for diagnostics:
External PLC input for the SPL
External PLC output for the SPL
Internal PLC input for the SPL
Internal PLC output for the SPL
Marker for SPL
The timeout value in the crosswise data comparison is ex‐
tended by a factor of 10
PS-communication error, in conjunction with PROFIsafe,
an error is signaled
CDC error "SPL protection status" (Status NC: $MN_PRE‐
VENT_SYNACT_LOCK not equal to PLC: SPL_READY)
0 -> 1 communication timeout detected, PLC will go into
stop in 5 s
NCK signals a stop to the PLC.
crosswise data comparison error if the value is not equal to
0
CDC stack level display
(diagnostics capability: How many SPL signals currently
have different levels)
