DB21, ...
DBX36.4 Interrupt processing active
Edge evaluation:
Signal state 1 or One or several channels in the mode group are not in the required operating state as the result of an
edge change active interrupt routine. The signal is not set if an interrupt routine is running in a program mode.
0 → 1
Signal state 0 or All channels are operating in the required mode.
edge change

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

DBX37.6 Read-in disable is ignored
Edge evaluation:
The following machine data are used to specify that the read-in disable (DB21, ... DBX6.1) is to be
ignored:
•
•
•
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))
