1. I do not have an IO map and I would like to pull all values from a Siemens PLC into the PI Data Archive
2. I want live data readings, not UFL loaded values
3. I know there is Siemens PLC 7 to Kepware OPC DA Server to PI OPC DA Interface to PI Archive method, but would rather not use this one. Seems like too many points of failure.
What I am unclear on is the PI Connector for Siemens SIMATIC PCS 7. Does this PI Interface work with just the Siemen S7-1200 PLC HMI combo?
