ABB Releases Next Generation System 800xA High Integrity Safety System

First released in 2005, System 800xA High Integrity offers the flexibility of hosting both safety and process-critical control applications in the same controller, providing logical separation of control and safety functions.

ABB (www.abb.com), Zurich, recently released its next generation System 800xA High Integrity safety system. According to the company, this SIL 3 rated Safety Integrated System (SIS) provides the highest level of integration of safety and control on the market today; its controller received its SIL 3 (for Safety Integrity Level) certification from Germany-based TÜV in November 2008.

“This next generation safety system offering is a continuation of our ongoing commitment to help our customers operate more safely and efficiently, to protect their vital assets while they improve their productivity and maximize uptime,” said Kristian Olsson, manager of ABB’s Safety Center of Excellence. “The latest version of System 800xA High Integrity provides the highest level of safety and process integration available in the marketplace; it harnesses the benefits of the 800xA environment to ensure significant savings across all stages of the system lifecycle. It complements ABB’s robust portfolio of leading edge safety solutions, products and services.”

The company has been involved in safety system development and delivery since 1979, when it commissioned the first emergency shut down system on the Statfjord B offshore oil platform in the North Sea. ABB is commemorating its 30 years of extensive safety experience in 2009.

System 800xA High Integrity leverages System 800xA’s common engineering tools, human system interface, historian, audit trail, asset and device management applications. The system is available up to and including Quad configuration to allow end users to tailor their safety system solutions to specific process requirements to optimize efficiency and cost.

Two in one

First released in 2005, System 800xA High Integrity offers the flexibility of hosting both safety and process-critical control applications in the same controller, providing logical separation of control and safety functions. This “same yet separate” architecture protects personnel, the plant and the environment while proving operating efficiencies, ABB says. ABB worked closely with customer Dow Chemical to develop this system and make it available commercially, as Dow had experienced benefits from this approach in its own proprietary system.

The latest version of the System 800xA High Integrity SIS includes several new features, including embedded hardware and software diversity in the logic solver and I/O subsystem, with diverse execution paths to detect any potential random failures. It includes additional SIL 3 libraries for shut-down applications, and provides combined non-SIL, SIL 2 and SIL 3 applications for increased safety protection and process efficiency.

While embedded safety and control is one option offered by System 800xA High Integrity, the customer can also deploy it in several other possible configurations. The system was designed at the outset to be able to operate as a stand-alone safety system, or can also be integrated with the process control system while it maintains physical separation of control and safety functions.
