Why do I get "you have connected two terminals of different types"

[tst]

The polymorphic selection is OK, because you have the DBL array coming out of the VI fine, and there doesn't appear to be anything wrong with the subVI, because you would have seen a "subVI is not executable" error.

The fact that the sink is recognized as void causes me to think that there may be something wrong with your LV installation. The only way I managed to recreate your error was by going into the subVI and disconnecting the FP IO control from its terminal in the connector pane and then reselecting that polymorphic instance (because the automatic selection immediately changed it when I disconnected it).

Try looking inside the subVI to see how its connector pane is set up. Use what becktho suggested to check all the polymorphic instances. If you do find that it's disconnected, you should check the other FP VIs as well. Then, I suggest you post the actual temp measurement VI (backsave to 7.0) so we can try it, and the next step will probably be doing a repair on the LV installation.

Tried reinstalling before, and changing to a fresh VI, but the same happens.  However, over the weekend I hope to install it on a different PC and see where things go from there.  I'll keep you all informed!

I have the same error "These cannot be wired together because their data types (numeric, string, array, cluster, etc.) do not match. Show the Context Help window to see what data type is required.
The type of the source is word [16-bit integer (-32768 to 32767)].
The type of the sink is DAQmx Device." but i can't find the option about "disable indexing" at all. where it is?

Vi i used is the first example0 "RC Transient.vi"

You don't need "enable indexing" as this has to do with loops.

Just delete the constant you wired. Point to the terminal with the wire-tool, right-click and select create constant.

Hope this helps.

it doesn't work 😕 something else i can do please?

Doesn't work 😕 something else i should try?

[becktho]

Try an "DAQmx Device Name Constant" (see picture).

Why did my previous suggestion not work?

Just now I tried to create one diagram after managing to do it Simulink. http://postimg.org/image/hswnsla0h/ But I got the error on the type compability, to be more exact On array and one-unit item compability of the same type –despite I have no similar error in SL. Should I correctly understand that I cannot fork the wire more tan once. If I have the wire could I branch it to for example 6 items? I refer here the image. In the second case I have the same error with Boolean type. I subtract two numbers and its checked twice is it >=0 or NOT equal to 0, than go inside the selector function but it evokes the error. Here it forkes just once?? So what I need to do here. Should I build array here? http://postimg.org/image/3ldn2d2q3/

Instead of adding a new message to the end of a long, 10-year old thread.  Just continue in your original thread!

I got the same problem, the representation is double and they all have the same length of data but cannot be connected either to xy graph or waveform graph.  What could be the problem?
