A cross connection is a logical connection between I/O signals
of type digital (DO, DI) or group (GO, GI), that allow one or several I/O
signals to automatically affect the state of other I/O signals.
Using cross connections is a simple way to interconnect I/O
signals and let the robot system handle I/O activity
without having to execute any RAPID code.
Cross connecting I/O signals is a good alternative if there is
an input I/O signal in the process that, when activated, automatically activates
one or several output I/O signals.
It is also possible to construct more complex conditions by
combining up to five different actor I/O signals with operators. The actor I/O
signals can also be inverted.
