A Modern Approach to Increase Safety Integrity

21 March 2016

The DeltaV SIS™ system takes a modern approach to increase safety integrity while improving process availability. DeltaV SIS continuously monitors plant safety devices’ status and diagnoses the health of the entire safety loop - dramatically reducing your risk. The logic solver, certified to safety integrity level (SIL) 3, reduces installation, commissioning, and maintenance costs while substantially reducing your equipment footprint.

Improve Safety Integrity - Know your safety system will perform when called upon.
The modern DeltaV SIS™ system takes into account devices’ predicted lifespan and pre-empts end of lifecycle with maintenance notifications and testing, so your SIS integrity stays stable longer.

Maintain Project Schedule, While Adapting to Project Changes - Manage late changes with Electronic Marshalling’s flexibility.
DeltaV SIS with Electronic Marshalling lets you maintain safe operations without putting production at risk every time you make a system change. Simplify design, installation, wiring, and commissioning while eliminating traditional system re-work and redesign.

Look at Space Differently - Mixed I/O and wiring in a single cabinet.
DeltaV SIS enables you to mix I/O, and bring homerun cables straight from the field into a standard cabinet. So small spaces are less limiting - even during hot cutovers when cabinet contents are being reorganised and the system seems to grow ten-fold.

Reduce Undetected Failures - Optimise diagnostics for the entire safety loop.
Be confident that every safety loop will operate when needed. DeltaV SIS provides an integrated, constant monitoring approach for the complete safety loop – from sensor, to logic solver, to final control element.

Overcome Complicated Integration - Smooth integration based on open communication standards.
Whether you require a standalone or integrated safety system, your DeltaV SIS solution will meet IEC 61508 and IEC 61511 requirements for physical separation and independence of safety and control. Integrate smoothly with other vendors’ control systems using standard communications interfaces.

Reduce Engineering Effort - Reduce engineering complexity with TÜV- and exida-certified function blocks.
The IEC 61508-certified SIS function blocks deliver functionality right out of the box, simplifying the implementation of complex SIS applications. No custom code is required to implement common SIS tasks. The result is faster configuration and troubleshooting of SIS logic.

Streamline Proof Tests - Reduce field testing and planned shutdowns.
Proof tests ensure effective system operation and integrity. The DeltaV SIS system offers alternatives to traditional proof testing. Partial stroke testing on HART-enabled devices can give you the option to extend the time between full proof tests on valves.

Simplify Safety Lifecycle Management - Built for IEC 61511 compliance.
DeltaV SIS is built for IEC 61511 compliance, providing stringent change management, security management, and documentation tools. The system is certified by TÜV and exida for use in SIL 3 applications without restriction.
