Tab. 2/7: Example of a tool change configuration which requires special attention with
the addressing (see text above)
2−20
Note
The following example makes clear that with the tool
change configuration you must be very careful, especially
in using the input and output addresses.
In configuration 1 in Tab. 2/7 a lamp is connected to the
2nd. output module as a signal generator. In configuration
2 an actuator is connected to the 2nd. output module. In
both cases address O23.7 is used.
Take into account in the controller that the lamp now lies at
address O25.7 and an actuator at O23.7.
