Parameterization
Effect of mode group-specific signals
The effect of the mode group-specific signals (NC/PLC interface signals DB11) on channels
of the mode group that is currently processing the interrupt routines, is set in the machine data:
MD11600 $MN_BAG_MASK.bit n = <value>
Bit
0
MD11600 also controls whether the internal program execution mode is imported only for the
channel in which the interrupt routine has been activated, or to all channels in the mode group.
Bit
1
If, because of the machine data setting, the channel in which the interrupt is being processed
has left the mode group, the mode group signals "Mode group reset", "Mode group stop", etc.
have no effect on this channel. In this way, the interrupt routine is run without being disturbed
by the mode group signals.
Parameterizable start enable
In the basic setting, the start of an ASUB is blocked by the following states in the channel:
● Stop through NC stop, M0 or M01
● Not all axes in the channel are referenced
● Read-in disable is active (DB21, ... DBX6.1 = 1)
The start can be enabled for specific states via the following machine data.
564
ASUB start
Control system reaction
not possible
The signal "Interrupt request not possible" is generated.
not possible
The "request was canceled because of an alarm" signal is generated.
Value
Meaning
0
The mode group-specific signals (NC/PLC interface signals DB11) are effective.
1
The mode group-specific signals (NC/PLC interface signals DB11) are not effective.
Value
Meaning
0
A mode group switchover is performed in all channels of the mode group.
1
An internal mode group switchover is only performed in the channel in which an
interrupt routine is active (only possible with bit 0==1).
