The PROFIBUS service data part in both the command and response
depends on the PROFIBUS service to be transmitted / received, and will
therefore be different in length and contents for every service. Also, the
response error codes will depend on the services requested. The common
parameters are described below. Each supported service will be described
separately after the common parameters.
