3.4.5 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)'
3.4.6 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.
