1) From SW 3.1 the following applies:
The signals are assigned to the process data in the actual value telegram using P0916:17 (PZD actual
value assignment, PROFIBUS) (refer under the index entry "Process data, configuring").
2) Before SW 3.3, the following applies:
This process data is only available if clock–synchronous operation is also running.
3) Process data for encoder 2 must be activated via P0879.12.
4) Data type: U16/U32 ––> Unsigned integer 16/32 bit ; I 16/I 32 ––> integer 16/32 bit

The control signals, from the perspective of "SIMODRIVE 611 universal", are input signals and are
described in Chapter 6.4.3.
Also refer in the index under "Input signal, digital ...".
