Comment
0 = OUTSEP[1..8] No automatic trans-
fer, can be retrieved from the user pro-
gram (AWP)
1 = Transfer to the output byte, speci-
fied in OUTSEP[1..8] from OUT-
SEP_ADDR[1..8] by the basic pro-
gram
Address, input byte
Address, output byte
0 = commissioning phase
(for a crosswise data comparison er-
ror, a STOP D is not initiated)
1 = commissioning completed
(for a crosswise data comparison er-
ror, STOP D is initiated)
If DB18, DBX36.1 was set to 1, for a
crosswise data comparison error,
instead of an external STOP D, an ex-
ternal 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 extended by a fac-
tor of 10
0 –> 1 communications timeout de-
tected, PLC will go to STOP in 5 s
