Linking the message frame interface of the control unit with the output terminal
To link the message frame interface of the control unit with the actual output terminal,
follow these steps:
1. In the S7T Config project navigator, switch to the
"\SINAMICS_S120\Control_Unit\Inputs/Outputs" dialog.
2. There, go to the "Bidirectional digital inputs/outputs" tab.
3. Select the following parameterization for terminal X122:
– Function of the X122 DI/O 8 terminal -> "output"
– "Interconnection with -> r2090 bit 8 BO PROFIBUS PZD 1 parameter"
Note
On the PROFIBUS, the signals of the low-order byte will be switched with the
high-order byte. The bit interconnection to bit 8 comes from the byte-word rotation in
the PROFIBUS signal.
This completes the configuring in S7T Config.
