One more problem with OPC server.
Some tags were showing bad in Matrikon client. When checked in I/A, tags were
ok. As soon as I changed the values slightly in Foxboro I/A, tag became good in
Matrikon.
Why does AIM* OPC Server behaves like this. Does it needs the varying values
always. This problem comes with some tags and these tags keep on changing.
Can anyone guide.

Kashif Ijaz
