    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.

    Abstract: A Controller is capable of executing non-safety-related control logic. A safety module is added to the Controller in order to increase the safety-integrity level of a Control System. The Controller is then able to execute safety-related control of real-world objects. Such a Control System may, for instance, exist at an offshore production platform or in a hazardous area of a chemical plant

    Abstract: The present invention concerns revalidation of a compiler of control language for use in an industrial control system, each time the compiler has been used. In particular, the invention reveals a method to revalidate a compiler for compilation of a user-written program, which is intended for safety control of real world entities. The user-written program subject to compilation by the compiler is intended for execution in a device, which comprises functionality that adds safety features to an industrial control system. The invention ensures that no fault is introduced into the device due to error in the compiler code. Such an error may, for instance, occur during distribution of the compiler code or due to failure in a computer's memory or failure on a disk where the compiler code is stored. Hence, the invention ensures that no such fault is introduced into the control of real world entities which otherwise could lead to accidents that harm people or cause damage to the environment.

    Abstract translation: 本发明涉及在每次使用编译器时在工业控制系统中使用的控制语言编译器的重新验证。 特别地，本发明揭示了一种重新验证用于编译用户编写的程序的编译器的方法，其用于真实世界实体的安全控制。 由编译器编译的用户编写的程序旨在在设备中执行，该设备包括将安全功能添加到工业控制系统的功能。 本发明确保了由于编译器代码中的错误而无法将故障引入到设备中。 例如，这种错误可能发生在编译器代码的分发期间，或者由于计算机内存中的故障或存储编译器代码的磁盘上的故障而发生。 因此，本发明确保了对现实世界实体的控制没有引入这种错误，否则可能导致危害人身或造成环境破坏的事故。
