Application

Connecting sensors and actuators
Digital inputs and outputs can be used to connect various sensors and actuators to the two
12-pin connectors (X122 and X132) on the front panel.
The following types of digital I/O are used:
● Digital inputs
● Bidirectional digital inputs/outputs
The assignment of I/Os to functions can be parameterized freely by the user. Special
functions, such as probe input and cam output, can also be assigned to the I/Os.
The enables for the drive units and/or motors (Line Module, Motor Module) connected to the
control unit can be switched using the digital inputs.
