need to know the node address of the instrument on the FLOW-BUS, the process number and the parameter number
on the instrument.
The node address is the node address of the instrument on the FLOW-BUS. RS232 interfaces accept node address 128.
When sending messages to node address 128, the message will always be accepted, regardless the true node address
of the instrument on the bus.
The process can be found in the parameter table or has to be determined when nothing is filled in. In that case, the
process number most often is 1, but on devices with e.g. multiple sensor channels, the process will be 1 for the first
channel, 2 for the second, and so on up to 32. On these modules also process 33, 65 and 65 are multiplied in this way.
It is important to know that not all parameters are available on all (FLOW-BUS) instruments.
For more details about parameters and their use see also the technical documentation of your
instrument. The Bronkhorst software application FlowDDE also gives an overview of which parameters
are available on which devices.
