    Abstract: Oppfinnelsen omhandler forbedret pålitelighet i sikkerhetskritisk kontroll av objekter i den virkelige verden. Eksempler på objekter i den virkelige verden som er gjenstand for sikkerhetskontroll er gass/røyk/ild- deteksjonssystemer, oljeboringsutstyr, rør og rørledninger, destillasjonstårn, kompressorer, transportbånd, kjeler og turbiner. En testapplikasjon innbefatter alle relevante høynivå språkkonstruksjoner og utføres repeterende som assemblerkode i en industriell styreanordning, hvis CPU er gjenstand for feildeteksjon under on-line sikkerhetskontroll.

    Abstract: A method to revalidate a compiler intended for compilation of a user-written program for safety control in an industrial control system after it has been used. A test program is compiled a first time which test program is defined in a control language. The compiler is validated by verifying that the test program executes correctly. A first software is generated derived from the compiled test program intended for later comparison purposes. The test program is compiled a second time after the compilation of a user-written program. A second software is generated intended for a comparison based on the second compilation of the test program. The first software is compared with the second software, wherein the compiler is revalidated for any errors introduced between the first and the second compilation. Provided that the revalidation indicates no errors in the compiler, the user-written program is enabled to execute in a device with safety features for control of real world entities.

    Abstract: The invention deals with improved reliability in safety critical control of real world objects. Examples of real world objects subject to safety control are gas/smoke/fire detection systems, drilling equipment, pipes and pipelines, distillation columns, compressors, conveyor systems, boilers and turbines. A test application includes all relevant high-level language constructs and is repeatedly executed as assembler code in an industrial controller, which CPU is subject to fault detection during on-line safety control.
