[foxboro] OPC again...

Folks,
I have always wondered if OPC was not just intended to collect data, or is
it also considered a viable communication link for control?  I now have a
vendor that wants to perform advanced process control from their PC-based
software to specific control loops on the Foxboro System via OPC?  Read
measurement values, execute advanced control algorithms, write control
outputs, etc.
Is OPC considered secure, reliable, repeatable, etc. enough for control?

Your thoughts/recommendations?
