• The M2 and M30 functions have equal priority. Only M2 should be used.
• The IS "M2/M30 active" is present as steady-state signal after the end of the
program.
• Not suitable for automatic follow-on functions such as workpiece counting,
bar feed, etc. For these functions, M2 should be written into a separate block
and the word M2 or the decoded M signal should be used.
• Auxiliary functions must not be written in the last block of a program that
should result in a read-in stop.

Program test active
Signal(s) from channel (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 Program control "Program test" is active. Axis disable is set internally for all
axes (not spindles). Therefore the machine axes do not move when a part
program block or a part program is being processed. The axis movements
are simulated on the operator interface with changing axis position values.
The axis position values for the display are generated from the calculated
setpoints.
Otherwise, the part program is executed in the normal way.
Signal state 0 Program control program test is not active.
corresponding to ... IS "Activate program test"
IS "Program test selected"

Program status running
Signal(s) from channel (NCK → PLC)
Edge evaluation: No Signal(s) updated: Cyclic
Signal state 1 The part program was started with IS "NC start" and is running.
Signal state 0
• Program stopped by M0/M1 or NC stop or mode change.
• For single block mode, the block is executed.
• End of program reached (M2)
• Program aborted due to a reset
• The actual block cannot be executed
Special cases, errors,
...
The IS "Program status running" does not change to 0 if workpiece
machining is stopped due to the following events:
• A feedrate disable or spindle disable was output
• IS "Read-in disable"
• Feedrate override to 0%
• The spindle and axis monitoring functions respond
