3.5.2 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 three 14-pin X122, X132 and X142 front connectors.
The following types of digital inputs/outputs are available:
● Digital inputs (DI)
● Bidirectional digital inputs/outputs (DI/DO, IN/OUT)
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 measuring input and output for output cam) can be assigned to the
inputs/outputs.
The digital inputs/outputs on the X122 and X132 front connectors can be used by either
SIMOTION or SINAMICS (e.g. as enable signal for a drive).
The digital inputs/outputs on the X142 front connector are firmly allocated to SIMOTION.
