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 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.
