• Device Self-Diagnostics

• Identify dangerous failures in real-time

• Provide valve partial stroke

Improved Safety Improved Operability

• Trip on demand only

• New/improved device self diagnostics

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

3. Different tools for ESD than DCS.

4. Life-cycle cost is $$$

Diagnostics require 3rd partysoftware

Future FFFuture FF--SIFSIF ArchitectureArchitecture

Operation Engineering Asset Management

Future architecture will be a hybrid solution consisting of both conventional and FF-SIF I/O to a Safety Logic Solver/Host.
