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

[RicK.]

Why do I get the above error when the error box defines both source and sink as being the same type. It is occurring twice on the attached VI. See text on block diagram for the two locations with broken wires.

[eh]

You have "indexing enabled" on the two inputs in question into your for loop. Right click on each input and select "disable indexing". This will cause the input to come in as an array.

I'm getting a similar message.

The VI used is this: 

Temperature measurement.vi from NI example finder.

Using a FP-TC-120 with k type thermocouple and LabView 7.1 and latest software I can read the temperatures in MAX but get the old You have connected 2 terminals of different types.

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 FieldPoint IO.

The type of the sink is void.

error when I try to run it.  (Broken wire is clearly visable). 

I tried it with these two settings also,

FieldPoint\FP @ 169_254_0_2\FP-TC-120 @1\Thermocouple type @Channel 0 2

FieldPoint\FP @ 169_254_0_2\FP-TC-120 @1\Channel 0

and still get the broken wire / incompatable terminal types message.  I even tried taking the advice above, concerning 'disable indexing' at the tunnel.  However when attempting this the option is there (well enable indexing is) but in faded text, as it is not selectable.  Any other ideas how I can test my system out and run a simple display temperature on screen?

Thanks

Did you modify the example? Which wire is broken?

Could you post maybe a screenshot (no bmp please)?

[fios]

No, it wasn't modified.  I just used browse to insert the temp probe selection.  Got a screenie for you though, jpeg format.    The wee purple bridge is where I attempted to right click and 'disable indexing' but the option was faded, and so unavailable.

thanks so far 🙂

If you right-click the FP-VI select "Select Type" in the context menu. There you can select the type you want to use (Automatic should work best).

I'm sure the FP-tag doesn't match the datatype to acquire.

Just tried it matey...no luck.  Theres something small and daft I'm missing somewhere, but I cannot think what!

Have a look at the errors-window. What is the detailed description if you select the error of the two different terminals?

[fios]

Hope this screenshot is what you mean.  Thanks for the help so far by the way 🙂

Jpeg format again.

Long shot,

try disconnecting the FP VI, delete it and then replace it with the same function again.  Now wire up and see what happens.

Long shot, like I said.

Hope this helps
