Currently we have a modbus link to the DCS and then we send this data to PI through the DCS connector.
I was wondering if there is a connector or interface for GE Mark 6?
According to search for GE Mark VI at our PI Interfaces and PI Connectors website, you can use OPC DA Interface. I also found PI Interface for GE FANUC Cimplicity HMI which might address your question (one of its aliases is GE Mark VI), but I believe OPC DA should work.
You mentioned Modbus. There is an existing Modbus interface (documentation here) that can be used to link Modbus devices like your PLC, or you could add an OPC server like Kepware and then use the PI-OPC DA interface like Piotr Wedziuk mentioned.
