High Integrity Safety System Works Alone or With Any DCS, PLC or HMI
Jane Alexander | June 9, 2014
ABB has released its High Integrity (HI) safety system for use with any ABB or third-party control system, PLC or operator interface. This TÜV certified release lets users leverage the system for any SIL 1-3 application and to interface all necessary information to the existing control system and/or operator interface.
The offering includes an object-oriented engineering environment with SIL certified safety libraries that efficiently support reuse and engineering throughout the entire safety lifecycle. The engineering environment includes IEC 6113103 programming languages and the easy to use 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, all of which provide an extra layer of authentication for maintenance bypasses and force control, as well as enhanced capabilities for troubleshooting and root-cause analysis.
According to ABB, its new Independent High Integrity system is well suited to applications where deep integration with the process-control system isn’t required, such as relay replacements or systems where visualization is provided by an ABB or third-party process panel, simple HMI or control system. The HI hardware and engineering tool are also 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
