I/O server does not appear

[BrunoVilelaMS]

Good Morning!
I'm trying to create a communication via OPC, however, when I click on My computer, the I/O server option does not appear. Already uninstalled and installed the DSC and still does not appear.
Do I need any more installers?
I use Labview 2018 and both are enabled.

Can anybody help me?
Thank you very much in advance

Hi, 

Depends on what server you want to communicate with, is it OPC DA or OPC UA? 

For the second one you will need NI OPC UA Toolkit, For the first one make sure you have downloaded DSC Run-Time System. 

Also would be better if you share what NI SW you have installed, there might be compatibility problem. 

Have you checked if all versions are capable to work with each other? 

Thx.

Hi Idasyan!

It would be in OPC UA. I believe it's the version. My Labview is 2018 and my DCS is 2019

I will try to find the 2018 version

thank you!
