DeltaV SIS is a key component of Emerson's Smart SIS solution, which is an extension of the PlantWeb digital plant architecture, providing an integrated approach to complete safety loops -- from sensor to logic solver to final control element. The TÜV-certified DeltaV SIS system, rated for SIL3 applications, includes:
Bulky logic solvers and multiplexers can now be replaced with16-channel, self-contained, state-of-the-art logic solvers that support continuous health monitoring of the entire loop. The DeltaV SLS Logic Solver, built for digital communications with safety sensors and final control elements, uses the power of predictive field intelligence to increase overall reliability of the complete safety instrumented function. It's designed for use in SIL 1, 2 and 3 safety applications as defined by IEC 61508.
Examples of ways to use smart SIS functionality in DeltaV SIS to improve your plant's reliability include:
- Use valve health from partial stroking in logic
- Use non-primary HART variables for Abnormal Situation Prevention
- Detect mismatch of the analog and digital HART PV signals resulting from potential earth leakage current
- Understand the faults in a smart device to increase process availability
- Detect non-critical faults to alert preventative maintenance.
The DeltaV SIS system shuts down your plant when needed for safety, but keeps you running safely when devices fail.
