Business users need to view production data from the historian without opening a direct session into the control network. Where should the replica server be placed?
- A.At level 2 inside the control cell
- B.In the industrial DMZ between zones
- C.At level 0 beside the field sensors
- D.At level 4 with the corporate mail server
Why B is correct
A replica in the DMZ lets the plant historian push data outward while enterprise users never connect into the control zones. A level 4 location would require inbound paths into OT and levels 0 and 2 are far too deep.
