Tag Query Error

[Former Member]

Hi,

I am getting the following tag query error -

[ERROR] [Tag_Query_0]Exception occured [06 - Posting the request]: ERROR_ON_LOAD [java.lang.Exception: Response timed out, request terminated]

Can somebody explain how to fix this?

Regards,

Chanti.

If you are going through a UDS, make sure the services are running.

It sounds like there is no connection between MII and the data repository.

The UDS is running.

try do a tag or grouplist query to see if there's a connection - rules out a possible issue with any particular tag.

Its giving a java.io.EOFException error when I run the transaction.

But, I am able to see the tags in the "Tag Query Details" section.

Also getting the error "java.net.SocketTimeoutException: Read timed out".

What is the status of the data server? Are there a large number of data points being returned? And if you run a smaller number of tags or smaller rowcount, do you still see the problem? What mode are you configured for? Does the query work by itself and fail in the transaction?

The status of the dataserver is "Running". The query works fine for a simulator server. However, it fails (both as a query and transaction) when I run it for the actual OPC server. It fails even when reading a single tag. Mode??? I am using "Current" mode.

We are experiencing these problems ever since we upgraded to 12.1. It used to work fine in 12.0.

What is the OPC server that you are connecting to?
