Error Browsing OPC

Hi,

I install a Bekhoff OPC server to collect the data form there PLC. I could browse the server to get the tag a couple of time but most of the time I got an “Error OPC Browsing”.
The version of Ignition install on the server is 7.6.4. The issue may be due to the fact that the server run on xp with a old version of JAVA and Internet Explorer.

Here is the log file that I got.

Regards,

It looks to me like your OPC Server isn’t responding within the 120 second time limit. Is this an OPCDA server that you are trying to get connected to? Is it a remote connection or a local connection?
