SAFETY MANUAL 8000 Series Certified family of products for use in a wide range of controls applications including safety, continuous process, supervisory control/data acquisition, and integrated control and safety. Communicatio ns Interface An intelligent communications module which interfaces between a TMR Controller and an Engineering Workstation, third party equipment or other TMR Controllers. TMR Processor A processor for use in safety-related applications of the 8000 series system. Handles application program execution, diagnostics and reporting functions. The TMR Processor uses three high performance RISC processors based on patented TMR architecture arranged in a lock-step configuration. TÜV Certification U Voting System Watchdog Independent third party certification against a defined range of International standards including DIN V VDE 0801, IEC 61508, IEC 801. Units of electronic module size (1-¾ inches). Redundant system (e.g. m out of n, 1-oo-2, 2-oo- 3 etc.) which requires at least m of the n channels to be in agreement before the system can take action. Watchdog circuitry provides dynamic and/or static monitoring of processor operation and is used to annunciate processor or processor related failures. Doc No P8094 Issue 14 September 2003 Page xvi
