Note
An open input is interpreted as "Low".
Terminal G1 must be connected for the digital inputs to function. The following alternatives
are available:
● Connect the carried digital input reference ground to M1.
● Create the bridge between terminal G and terminal G1.
Using the digital inputs/outputs
Connecting sensors and actuators
Digital inputs and digital outputs can be used to connect various sensors and actuators to the
12-pin X122 front connector.
The following types of digital inputs/outputs are used:
● Digital inputs
● Bidirectional digital inputs/outputs
Bidirectional digital inputs and outputs can be configured individually as digital inputs or outputs.
Assignment of the inputs/outputs to functions can be parameterized as required. Special
functions (e.g. input of the measuring input) can be assigned to the inputs/outputs.
The enables for the drive units and/or motors (Active Line Module, Motor Module) connected
to the Control Unit can, for example, be switched using the digital inputs.
Digital inputs
There are 4 digital inputs on the CX32.
The electrically isolated inputs can be used as freely addressable inputs.
Bidirectional digital inputs/outputs
4 digital inputs/outputs (DI/DO) are available on the CX32.
When the DI/DO are assigned as digital inputs, they can be used as follows:
