Default settings via the PLC user program
The keyswitch switch positions are transferred to the NC/PLC interface via the basic PLC
program. The corresponding interface signals can be modified via the PLC user program. In
this context, from the point of view of the NC, only one switch position should ever be active,
i.e.,. the corresponding interface signal set to 1. If, from the point of view of the NC, a
number of switch positions are active at the same time, switch position 3, i.e., the keyswitch
position with the least restricted access rights, will be activated internally by the NC.
