The digital inputs and digital inputs/outputs (X122/X132) are mainly assigned to SINAMICS Integrated. Through configuration (frames 39x), you can, however, also use the digital inputs and digital inputs/outputs (X122/X132) for the CPU. The following applies:

A digital output is always only available exclusively to SINAMICS Integrated or to the CPU.

If you use a digital input for the CPU, you can also interconnect the digital input at the drive end.

You can configure the digital inputs and digital inputs/outputs (X122/X132) channel by channel. To do so, go to the function view in the project tree under "Automatic speed control" > "Parameter assignment" and set the configuration under "Inputs/outputs".

Bidirectional inputs/outputs are configured in the following configuration mask.

You can assign the SINAMICS digital inputs and digital inputs/outputs (X122/X132) using frame 39x of the PU. The status information of the digital inputs and digital outputs is then transferred at the PROFIdrive PZD sampling rate (p2048). The inputs/outputs are also sampled in the configured sampling time for the digital inputs and digital inputs/outputs (p0799). The application of the output values and return of the input values are therefore subject to dead times and jitter.
