2.5.5 06h Write Single Register
Enables writing of a single 16Bit parameter.
Example:
Parameter P102, parameter set 2 is written with the value 0x0123 (see also the item "Parameter access" in
Section 2.8 Description of parameters).
Response (Slave Master)
2.5.6 10h Write Multiple Register
This command enables several parameters to be written consecutively, and for parameters with a data length
of 32Bit.
In the process data area, all process data of the P050 parameter array can be written simultaneously.
If parameters are written with this access, only a single parameter can be written with a telegram. This access
is used to write 32Bit parameters.
The parameter (P050) "Process data IN" and (P051) "Process data OUT" are executed in the
background and are not visible to the user. From a structural point of view, these are array
parameters ([-01 … -04]). Assignment of the setpoints in parameter (P050) is carried out via
the parameters (P546 (… P548)). The return of the actual values in parameter (P051) is
assigned in parameters (P543 (… P545)).
