Signal r Read

Type Value range Remarks
Parameterization part
INSEP_VALID[1..8] r/w 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
OUTSEP_VALID[1..8] r/w 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
INSEP_ADDR[1..8] r/w Int 1..EB Max Address input byte
OUTSEP_ADDR[1..8] r/w Int 1..AB Max Address output byte
SPL_READY r/w 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)
STOP E 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
Data area/status
SPL_DATA Useful data:
INSEP[1..64] r Bool External PLC input for SPL
OUTSEP[1..64] r/w Bool External PLC output for SPL
INSIP[1..64] r Bool Internal PLC input for SPL
OUTSIP[1..64] r/w Bool Internal PLC output for SPL
MARKERSIP[1..64] r/w Bool Marker for SPL
SPL_DELTA Signal differences for diagnostics:
INSEP[1..64] r Bool External PLC input for SPL
OUTSEP[1..64] r Bool External PLC output for SPL
INSIP[1..64] r Bool Internal PLC input for SPL
OUTSIP[1..64] r Bool Internal PLC output for SPL
MARKERSIP[1..64] r Bool Marker for SPL
CMDSI r/w Bool Timeout value in crosswise data comparison
is extended by a factor of 10
