DB21, ...
DBX36.4 Interrupt processing active
Edge evaluation: Signal(s) updated:
Signal state 1 or
edge change
0 → 1
One or several channels in the mode group are not in the required operating state as the result of
an active interrupt routine. The signal is not set if an interrupt routine is running in a program mode.
Signal state 0 or
edge change
1 → 0
All channels are operating in the required mode.
Corresponds to .... MD11600 $MN_BAG_MASK
DB21, ...
DBX37.6 Read-in disable is ignored
Edge evaluation: Signal(s) updated:
The following machine data are used to specify that the read-in disable (DB21, ... DBX6.1) is to be
ignored:
• MD11602 $MN_ASUP_START_MASK, Bit 2 = 1 (start also permitted if read-in disable is active)
• MD20116 $MC_IGNORE_INHIBIT_ASUP (execute interrupt program in spite of read-in disable)
• MD20107 $MC_ PROG_EVENT_IGN_INHIBIT (Prog events ignore read-in disable)
Part program blocks for which read-in disable is ignored are designated as read-in disable-
inoperative.
Signal state 1 Read-in disable is active (DB21, ... DBX6.1==1) AND part program block is read-in disable-
inoperative.
Signal state 0 Read-in disable is not active (DB21, ... DBB6.1 == 0) OR
(read-in disable is active (DB21, ... DBX6.1 == 1) AND part program block is read-in disable-
operative)
Corresponds to .... DB21, ... DBX37.7 (Stop at block end is ignored during single block (SBL))
DB21, ...
DBX37.7 Stop at block end is ignored during single block (SBL)
Edge evaluation: Signal(s) updated:
The following machine data and part program commands are used to specify that the stop at block
end during single block (DB21, ... DBX0.4 == 1) is to be ignored:
• MD10702 $MN_IGNORE_SINGLEBLOCK_MASK (prevent single block stop)
• MD20117 $MC_IGNORE_SINGLEBLOCK_ASUP (execute interrupt program completely in spite
of single block)
• MD20106 $MC_PROG_EVENT_IGN_SINGLEBLOCK (Prog events ignore single block)
• SBLOF (suppress single block), SBLON (cancel single block suppression)
Part program blocks for which stop at block end during single block is ignored are designated as
single block-inoperative.
