Data Description
8.6 Interface signals
Remark
The timeout value in the crosswise
data comparison is extended by a
factor of 10
PS--communication error, in con-
junction with PROFIsafe, an error is
signaled
CDC error "SPL protection status"
(Status NC: $MN_PREVENT_SYN-
ACT_LOCK not equal to PLC:
SPL_READY)
0 --> 1 communications timeout de-
tected, PLC will go to 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)
Single--channel signals from the
PLC to NCK
Single--channel signals from the
NCK to the PLC
Status signals from NCK to PLC
0 = Alarm27350 + STOP D/E
1 = Alarm 27350
2 = Alarm 27351 (only display, self--
clearing)
3 = No system reaction
0 = Normal mode
1 = Communication error
0 = output of process values
1 = output of substitute values
