Safety System Offers Reliability

ABB released its High Integrity (HI) safety system for use with any ABB or 3rd party control system, PLC or operator interface. The TÜV certified release gives users the ability to utilize ABB’s High Integrity safety system for any SIL 1-3 application and to interface all necessary information to the existing control system and/or operator interface.

The Independent High Integrity offering includes an object oriented engineering environment with SIL certified safety libraries that support reuse and engineering throughout the entire safety lifecycle. The engineering environment includes IEC 6113103 programming languages and Diagram Editor as well as safeguards against non-SIL compliant configurations.  Core functions include system security, access control, confirm operations, force control, time tagging to millisecond accuracy, audit trail, system diagnostics and difference reporting.  These functions provide an extra layer of authentication for maintenance bypasses and force control as well as enhanced capabilities for troubleshooting and root cause analysis.

Connectivity options and protocols including Modbus and OPC provide the ability to interface to process panels, ABB control systems or 3rd party software and control systems.  The non-interfering communications protocols enable read access to the safety system data for any type of display.

ABB’s Independent HI safety system is suitable for applications where deep integration with the process control system is not required, such as relay replacements or systems where visualization is provided by an ABB or 3rd party process panel, simple HMI or control system.  The High Integrity hardware and engineering tool are used with ABB’s Freelance and Symphony Plus control systems to deliver safety solutions that are SIL3 certified to Edition 2 of the IEC safety standards.
