Processing time of parameters
The response time is the time between a query and its answer. For write queries, this is around 1 second per parameter
and for read queries around 500 ms. The response time between the write command via Modbus and the response
via Modbus is up to 1 second. When reading back parameter changes, it is necessary to either wait for the response
or take the response time into account.
