Hello, with a Control Logix 1756-L63 processor, and Factory Talk gateway OPC server, I'm looking to achieve 10ms data for ~20 tags. There are other tags on the processor, but don't require the fast scan class. Currently getting data at around 70ms rate. Some tests using a newer L83 processor, rates of 2ms can be achieved. Would the PI Connector for Ethernet be more efficient and faster than OPC?
