Explanation
 A "Write.req" is used to pass the data set (DB47) to the slave in the form of a parameter
request.
 With "Write.res" the master receives the confirmation for the receipt of the message.
 The master requests the response of the slave with "Read.req".
 The slave responds with "Read.res (-)" if processing has not yet been completed.
 After parameter processing, the parameter request is completed by transmitting the
parameter response to the master with "Read.res (+)".

Note!
A parameter request refers to one or several parameter(s) (multi-parameter
request).
