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 14-pin X122 front connector.
The following types of digital inputs/outputs are used:
● Digital inputs (DI)
● Bidirectional digital inputs/outputs (DI/DO)
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 digital inputs/outputs on the X122 front connector can be used by either SIMOTION or
SINAMICS (e.g. as enable signal for a drive).

Note
For optimal noise immunity of the digital inputs, the use of shielded cables is necessary in
certain cases. This is necessary when the digital inputs are to be used as
 Inputs of measuring inputs or
 Inputs for the external zero mark
