DBX35.7 Channel status reset
Edge evaluation: No
Signal state 1 The signal changes to 1 as soon as the channel goes into the reset state, i.e. no processing taking
place.
Signal state 0 The signal is set to 0 as soon as processing takes place in the channel, e.g.:
● Execution of a part program
● Block search
● TEACH IN active
● Overstore active
DB21, ...
DBX36.4 Interrupt processing active
Edge evaluation: No
Signal state 1 One or more channels in the mode group are not in the desired operating mode as the result of an
active interrupt routine.
Note: The signal is not set if an interrupt routine is running in a program mode.
Signal state 0 All channels are operating in the required mode.

DBX36.5 Channel is ready
Edge evaluation: No
Signal state 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 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: No
The following machine data is 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-inopera‐
tive.
