Existing Existing ESDESD ArchitectureArchitecture
Operation Engineering
Sensors, Logic Solver, and Final elements make up each ESD loop.
1. Today, sensors and valves are hardwired with no continuous two-way communications…no direct way to see diagnostics within ESD logic solver.
2. Data has to be mapped from ESD to DCS (OPC, Modbus)
3. Different tools for ESD than

4. Life-cycle cost is $$$
Diagnostics require 3rd partysoftware
