FlowDDE parameter numbers

Reading/changing parameter values via FlowDDE offers the user a different and user-friendly interface to the

instrument. A DDE-parameter number is a unique number in a special FlowDDE instruments/parameter database and

not the same as the parameter number from the process on an instrument. Node-address and process number will be

translated by FlowDDE to a channel number.

An instrument parameter can be changed by using the application name: ‘FlowDDE’ with only:

topic, used for channel number: ‘C(X)’

item, used for parameter number: ‘P(Y)’

Baud rate setup

Make sure that the instrument’s baud rate corresponds with the baud rate of the application the instrument is

communicating with. For single-channel instruments the selectable baud rates are 9K6, 19k2, 38k4, 57k6 and 115k2

Baud; for multi-channel instruments the selectable baud rates are 38k4 and 115k2 Baud.
