6.7 Digital inputs and digital inputs/outputs X122, X132 and X142
The digital inputs and digital inputs/outputs at interfaces X122, X132 and X142 are designed
for the connection of sensors and actuators.
The digital inputs and digital outputs at interfaces X122 and X132 are mainly assigned to
SINAMICS Integrated. Through configuration (frames 39x), you can also use the digital
inputs and digital outputs (X122/X132) for the CPU.
The digital input/outputs at interface X142 are assigned to the CPU of the SIMATIC Drive
Controller and that assignment is fixed.
Using the digital inputs and digital outputs
Digital inputs/digital outputs come in the following types:
● Digital inputs (DI)
● Bidirectional digital inputs/outputs (DI/DQ)
Bidirectional digital input/outputs can be configured channel-by-channel as digital input or
digital output.
Assignment of the input/outputs to functions is freely configurable. Technology functions (for
example measuring input and output cam) can also be assigned to the inputs/outputs.
