"real time communication wizard" "control list"

[gfr.ferrari]

Hi to everybody,

I use labview to develop models of the circulation. Some of this models are based on a hybrid structure that permits the interaction with a physical environment. Till now, they were developed in labview (under windows). With a Polish colleague, I am now trying to transform one of the models into a real time system. However, when we use the real time communication wizard it does not list all of our controls and variables (the warning message at the end of the process says: one or more of the selected controls/indicators will leave behind an invalid control reference, local variable, property node or invoke node). The software is essentially based on two while loops: the internal solves all the the equations of the model and contains AD and DA conversions. The external loop contains control and data presentation. I could of course write a new code separating the two cycles. However, the best would be to leave, if possible, the code unchanged. Do you have any suggestion?

Many thanks in advance.

Hi Gianfranco,

you can find the explanation about RT Communication Wizard (RTCW) at link:

http://zone.ni.com/devzone/conceptd.nsf/webmain/a6f17ee4adcab99686256d5e0053e210

The problems you have encountered are due to the RT architecture, in fact RTCW transfers the front panel objects from RT to Host PC because RT target can't manage User Interface.

RTCW is not able to transfer automatically the Property Nodes linked to any front panel object from RT VI (TCL.vi) to Host VI, so you must manually transfer them.

If not all your controls and indicators are listed in the RTCW list, there are 2 reasons that you can find at link:

If you want to leave some controls and indicators within the TCL.vi you must uncheck them from the RTCW list.

I hope this help you.
