RE: Power Plant Monitoring

I personally agree that wireless is not so much as to take the place of wires as it is to measure all the stuff that was not measure before: missing measurements that were not included when the plant was orignally built. I see wires (hardwired or digital bus networking) used for the stuff "on the P&ID" complemented by wireless sensor networking for everything "beyond the P&ID". That is, the primary layer of automation is the wired ICSS (DCS+SIS) while wireless for pervasive sensing is a second layer of automation. See further explanation in these articles:

For a new plant, this has to be planned from the very beginning of a project
