Intermittent OPC Communication Problems

Hello,

We have a link between SimSCi Romeo 6.1 and Honeywell PHD 320.  We are reading tag data (point.parameter) from the PHD historian via an OPC connection.  The connection works fine, but there is a breakdown and disconnect some times.  Does anyone know where the OPC logs are on a Romeo Server where I can trace what is going on especially after a disruption.  Also is there anyway to turn up the OPC log levels?

Regards,
