7.4.3. Request parameters
The “G“ (GET) instruction is used to request from the SideStep the value of a parameter
via the Profibus. The SideStep responds with a GET instruction containing the parameter
value.
Where the parameter does not exist, an external diagnostic error with code 0x22 is
triggered.

When the parameter value in the GEMÜ SideStep changes, it is
immediately sent to the Profibus master. There is no need to
continuously request the parameter.
