3.5.2 Using the digital inputs/outputs
Connecting sensors and actuators
Digital I/Os 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 I/Os are available:
● Digital inputs (DI)
● Bidirectional digital I/Os (DI/DO, IN/OUT)
Bidirectional digital I/Os can be configured individually as digital inputs or outputs.
Assignment of the I/Os to functions can be parameterized as required. Special functions
(e.g. input of measuring input and output for output cam) can also be assigned to the I/Os.
The digital I/Os 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 I/Os on the X142 front connector are permanently allocated to SIMOTION.
