Trouble with NI-DAQ OPC Server

[Giovani]

Hi everyone !!!

I´m currently facing a problem which I can´t solve ! I´ll describe it so that you people can help me figure out a solution!

What I want to do is to make use of NI-DAQ OPC Server so that my tasks previously configured in NI-MAX can be accessed by a OPC Client. To test the connection I´m using QuickOPCClient from Kepware. The problems are the following :

1 - Although the devices and their tasks can be successfully accessed and tested inside NI-MAX, whenever I try to establish a connection to DaqOpc through NI Server Explorer an error occur and so I can´t communicate with the server.

2- Since it´s a very strange kind of error - I can, for instance access all the other OPC servers currently installed on my machine  using  both QuickOPCClient and NI Server Explorer - I decided to try desperate measurements !  I uninstalled the DAQ drivers - both traditional and mx - currently installed on my machine and installed them again ... to no avail ! The strange error persists !

Can anyone help me with this? As is always the case, any help will certainly be deeply appreciated!

Giovani 🙂

Hi Giovani,

When you try to connect to the server do you get any error messages?

Have you tried running through the NI-DAQ OPC Server Troubleshooting Wizard?  If it doesn't solve the issue, it may give you a better idea what the origin of the problem is.

Let me know if anything turns up in your troubleshooting!
