Overview of DB 18 signals
DB18
Signal r
Read
w-Write
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
