*1) :
The AOM attempts to increase the current further according to the control value. However, depending
on the burden effective resistance, the maximum output voltage of the AOM may be reached whereby
the current can no longer be increased.
Safety position after Power On:
After Power On of the CPU the data area of the outputs is initialized with the value -32768 (0x8000) as signal
for the safety position.
The outputs remain in the save position as long as the allocated register is overwritten with a valid output value
( <> -32768 (0x8000)) from AS or from IS Wizard.
