DBX36.4 Interrupt processing active
Edge evaluation: Signal(s) updated: Cyclic
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.

DBX36.5 Channel is ready
Edge evaluation: Signal(s) updated: Cyclic
Signal state 1 or
edge change
0 → 1
A channel is ready for a part program processing of machine axes, geometry axes and positioning
axes. These are already allocated corresponding to machine configuration and the current program
status of the concerned channels.
Signal state 0 or
edge change
1 → 0
The concerned channel is not ready for a part program processing of machine axes, geometry axes
and positioning axes.

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)
Corresponding to ... DB21, ... DBX37.7 (Stop at block end is ignored during single block (SBL))
