Type Value range Remarks
Bool 0 = INSEP[1..8] No automatic transfer, can be
supplied by the user program
1 = Transfer of input byte defined in
INSEP_ADDR[1..8] to INSEP[1..8] by basic
program
Bool 0 = OUTSEP[1..8] No automatic transfer, can
be retrieved by the user program
1 = Transfer to output byte defined in
OUTSEP[1..8] from OUTSET_ADDR[1..8] by
the basic program
Int 1..EB Max Address input byte
Int 1..AB Max Address output byte
Bool 0 = Commissioning phase
(no STOP D is triggered for crosswise data
comparison error)
1 = Commissioning completed
(STOP D/E is triggered for crosswise data
comparison error)
If DB18, DBX36.1 = 1 was set, and if a
crosswise data comparison error is
determined, then an external STOP E instead
of an external STOP D is transferred to the
drive
Useful data:
Bool External PLC input for SPL
Bool External PLC output for SPL
Bool Internal PLC input for SPL
Bool Internal PLC output for SPL
Bool Marker for SPL
Signal differences for diagnostics:
Bool External PLC input for SPL
Bool External PLC output for SPL
Bool Internal PLC input for SPL
Bool Internal PLC output for SPL
Bool Marker for SPL
Bool Timeout value in crosswise data comparison
is extended by a factor of 10
