The part program can now be enabled for execution in the channel with the START command on the condition
that certain signal states exist on the machine.
The following enable signals are relevant on the VDI interface:

• DB11 DBX0.7 (mode group reset) must not be present
• DB21, ... DBX1.7 (activate program test) must not be present
• DB21, ... DBX7.0 (NC start disable) must not be present
• DB21, ... DBX7.2 (NC stop at the block limit) must not be present
• DB21, ... DBX7.3 (NC Stop) must not be present
• DB21, ... DBX7.4 (NC Stop axes plus spindle) must not be present

Execution of command
The parts program or the parts program block is automatically executed and the the following interface signals
are set:
DB21, ... DBX35.5 (channel status reset)

The program is processed until the end of the program has been reached or the channel is interrupted or aborted
by a STOP or RESET command.

triggered:
• 10200 "No NC Start permitted with active alarm"
