DI: digital input; DI/DO: bidirectional digital input/output; M or GND: electronics ground;

M2: Functional ground
B = Bidirectional; I = Input; GND = Reference potential (ground)

Note
An open input is deemed to be "Low".
To enable the digital inputs to work, terminal M1 or M2 must be connected. The following
alternatives are available:
• Connect the carried digital input reference ground to M1 or M2.
• Insert a bridge between terminals M and M1 (or between M and M2).

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 two 12-pin X122 and X132 front panel connectors.
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. probe input and output cam) 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
The control unit has 8 digital inputs.
The isolated inputs can be used as freely addressable inputs.
Bidirectional digital inputs/outputs
The control unit has 8 digital inputs/outputs (DI/DO).
When the DI/DO are assigned as digital inputs, they can be used as follows:
