ControlLogix SIL 2New TüV Certification for Easy-to-use Add-On Instructions Simplies Use in Fail Safe and Fault Tolerant Applications

Easier to Use: The new certified ControlLogix with termination boards and software extends the fault tolerance down to the I/O level. New configurable software makes the system easier to use as the software routines provide the pre-developed logic for diagnostics, comparison, alarming and other functions identified in the safety manual. These routines are now encapsulated, transparent and are configurable. Previously, you had to write these programs.

• Extends the fault tolerance to the I/O. The previous system with the redundancy module provided fault tolerant only to the controllers.

• The fault tolerant ControlLogix provides very high levels of availability for those customers that cannot tolerate an unwanted safety system shutdown

• Certified by the TüV Rheinland adding credibility and assurance.

Reliability by DesignSophisticated diagnostics and high levels of reliability are standard design in ControlLogix controllers, I/O modules, and communication products. It is that same, standard design that readily provides the reliability needed to achieve SIL 2 certification.

Today’s manufacturers require safe, reliable systems to safeguard people, property, the environment, and reputations. Safety Integrity Level (SIL) 2 certification of ControlLogix products by TüV makes it simpler, easier, and less expensive for these manufacturers to meet growing standards compliance requirements worldwide.

What is SIL 2 Certification all about?A SIL is a numeric designator assigned to a safety system that indicates that system’s ability to perform its safety function. The SIL 2 TYPE certification of ControlLogix programmable automation controller (PAC) by TüV, an internationally recognized and accredited test laboratory certification center, assures the suitability of ControlLogix products for use in safety applications up to and including SIL 2.

TüV certification is based primarily on compliance with IEC 61508 “Functional Safety of Electrical/Electronic/Programmable Electronic Safety-Related Systems” requirements. It also includes a number of application-independent standards, IEC-61511 Functional Safety Safety Instrumented Systems for the process sector DIN V 19250 and VDE 0801, application-dependent standards, prEN 50156 for ESD applications, DIN EN 54 for fire and gas application, and environmental and electrical safety standards, IEC 61131-2, EN 50178, EN 50081-2, and EN 61000-2:2000. Rockwell Automation has obtained a TYPE approval and certification from TüV.

Standard Design Yields Exceptional SavingsThe ability to use standard, off-the-shelf ControlLogix products in SIL 2 applications means customers require no additional training and ensures that spares are readily available. That is why many major petroleum companies today use ControlLogix, saving more than 80% of the cost of other solutions.

Independent analyses have confirmed Safe Failure Fractions for the processors at well over 95%. Diagnostic I/O, including outputs that pulse test to verify that outputs are working, provide pre-emptive warnings of potential issues before they become reality. MTBFs of >100 years and low PFDs.

Such performance sets a new standard for reliability and availability – increasing safety, productivity, and profits while reducing down time, nuisance trips, and lifecycle costs for all customers.

Certified in Fail Safe and Fault Tolerant topologies For years, customers have successfully deployed ControlLogix SIL 2 systems in fail safe topologies. Additionally, with the certification of redundancy components, and the specially-designed 1492 termination boards for DC I/O and analog inputs, ControlLogix offers high-availability topologies, with fault tolerance for controller and communication products as well as the I/O system.
