How to read an array with OPC and Datasocket?

[Peachy]

Thanx for you answer unclebump,

Yes, Applicom OPC server is running on the same computer as LabVIEW and I'm using ethernet communication.

Please tell me how to do this and I'll check if it's working.

Thanx again!

Stephanie

P.S. I put 2 bitmaps in attachment of the OPC Client and Console Applicom, maybe I do something wrong there!?

What version of the applicom software are you using??

Version 3.8.0

Hi Stephanie,

Instead of setting up the DataBinding for the controls, let's try using the DataSocket VIs just in case that makes a difference.  I've attached a VI which I put together from two of the DataSocket shipping examples.  It should write an array to the OPC server and then read it back.  Give it a try and let me know if you have any success!

Good luck

Thanx to everyone who helps me!! I really appreciate this.

I found the error and that's pretty stupid haha

The mode in the Data Binding has to be "Read/Write" instead of "Write". (Shame on me hehe )

You're all awesome!

Thanx again

Stephanie
