1SSI

4.9 Control and Feedback Interfaces in Standard Mode

4.9 Control and Feedback Interfaces in Standard Mode
Note
For the 1SSI, the following data of the control and feedback interface are consistent:
Byte 0 to 3
Byte 4 to 7
Use the access or addressing mode for data consistency over the entire control and
feedback interface on your master (only for configuration using the GSD file).
Description
The two tables show the assignment of the control interface (outputs) and the feedback
interface (inputs):
