opc error 80040112

[Bertha]

I have been using DataSocket Select URL.vi to get a connection to the OPC Server and it has worked fine so far with Omron PLC(one driver) and NI OPC Servers 2009-2011 I was forced to switch to OPC Server 2012 one driver license since I only use one PLC but when I try to connect to the server using Datasockets from Labview I get the following error

Is there an issue I am not aware of. I have looked online but answers are not there or are vague. I would like some help please to solve the issue

Hi Bertha

Could you check for me to ensure that the NI OPC Server 2012 is licensed properly from within the NI License manager software?

Was the NI OPC Server 2009-2011 that you used licensed in unlimited driver mode?

Kind Regards

Here it is. Before there was not an option I used to order it online an there was only one so I'm guessing it was unlimited. now there is two single and unlimited and I chosed single since I only use one plc. I can see them on quick client I just cannot access them thru datasocket when I use Datasocket Select URL.vi I appreciate your help

Hi Bertha

Which version of LabVIEW are you using?

Kind Regards

Labview 2010 f2

Hi Bertha

If you open up the readme file for OPC Server 2012 it says:

"You can use NI OPC Servers with the following software applications:

• LabVIEW 2011 SP1 Full or Professional Development System
• LabVIEW DSC Module 2011 SP1"

It's probably not going to work with LabVIEW 2010 sorry.

Kind Regards

Well, Do you think they sell me a license for the older version?

FYI - This can also be caused by Using LV 2011 instead of LV 2011 SP1
