MixedGraph control

[nitad54448]

Hi

I am working on a pplication that controls several valves, flow controller, temperature and pressure. This is working (almost,.. I have problems with a Brooks controller....) but now I am having problems with mixed graph : it does not obey !

I attach here two files (a draft of an action engine), please check that you get the same results... :

You can add a step : on the top panel only pressure and temperature waveforms are shown.

change the action to Clear: the waveform "valve 1" from the bottom goes up ! Why ? I don't want it up ! Is this a bug ?

Also, how to I add a step to mixed graph (I mean not loosing the previous step ?)

thanks for help

Hi,

You should initialize the values into the state "clear", put all of them to 0 for example. See the attached VI in version 2011.

ok thanks, it works !

(I think NI should add this note in the Help file 🙂 or make a real help topic for mixed graph)
