A write request is first sent containing the parameter request.
If the write request is valid, the SI-EP3 acknowledges it with request accepted. The master then sends a read request. If
the SI-EP3 is still busy performing the internal parameter request, it will return a negative response with the error code
"0xB5" (State conflict). In this case, the master repeats the read request until the SI-EP3 has the PROFIdrive compatible
response data ready.
If the write request is invalid, a negative response is returned with an error code.
Base Mode Parameter Access - Local
The DO-ID field in the Record Data Object request header is not evaluated by the parameter manager. Parameters can be
read through any slot in the configuration.

Read block is used in read requests and responses. Write block is used in write requests and responses. The request
consists of unique identifiers for the connection, addressing information and length of the record data. The response also
contains two additional fields for transferring information.
