DeltaV OPC DA Tag Count

Hi

I have a single OPC client that connects to a DeltaV OPC Server via Matrikon Tunneller.

We are having some spurious disconnection issues which I think are related to exceeding the license limit of 2000 tags.

I cannot seem to correlate the tag count in DeltaV Diagnostics with the tag count in the client.

According to diagnostics, the client has 1465 connected tags whereas the tag count in the client is 1165.

Assuming that the client tag count is correct, I'm certain that it is, is there any other reason why I would see this difference?

Thanks for any thoughts!
