Problem with OPC and executable

[A.Salcedo]

Hello to everyone.

I have a program which works fine in Labview.

This program comunicates with a PLC via OPC Server.

When I create an executable and install it in another PC, it works but it can not comunicate with OPC Sercer...

In this PC I have installed DSC module and my program...

Should I instal anything special for doing that?

Thanks a lot

Do you get any specific errors?

[Sam_Sharp]

Did you license the DSC module with either a development or a deployment license? The DSC module requires a deployment license.

And where can I download that deployment license?

Have I to install this license in the PC which it will run the executable¿

[A.Salcedo]

No errors.... it just does not comunicate in a executable but it comunicates in a normal labview program... 😞

There is documentation available on the link I posted. The DSC Runtime will include a 2-hour evaluation license - after that you will need to install and activate a deployment license (in the NI License Manager).

But I have installed this module in both PCs and it does not work..

[Sam_Sharp]

Did you check the license status in NI License Manager? Do you have a green box next to the 'DSC Runtime'?

(I would also imagine that the DSC VIs in your application would also generate an error saying that the toolkit is not licensed - do you have error reporting / handling in your application?)

Isn't that how the NI OPC Servers license works rather than the DSC Runtime?  I'm pretty sure the DSC Runtime is either licensed or not with no evaluation options.  Additionally, it tends to hide from NI License Manager and handle things in the background from my experience.

Although, if the DSC module is running on the PC and the application works in the development environment, this is a moot discussion as the required DLLs are present and working with the DSC activation.

Does this executable work on the original development machine as an executable?

I do not try that.

Maybe I have to try that and come back here!
