The control system comes with an universal program, the customer can
choose the technology mode (Turning or Milling) with PLC user machine data.
The PLC can activate its start-up modes from two places.

The start-up switch PLC Stop can be activated either during operation or
power-up.
The debug mode (see "Operation and Programming", Chapter 7) causes the
PLC to remain in PLC Stop after the control system has powered up. All
power-up modes that have been set either via softkeys or via hardware start-
up switches will only come into effect after the next power-up of the control
system. The hardware start-up switch "PLC STOP" (position 4) is active
immediately. The priority of the power-up modes activated via the softkeys on
the operator panel is higher than that of the hardware start-up switches.
