Abstract: A procedure is provided to implement modifications to a running object-oriented program, in particular a program for controlling an automation facility. The program is stored temporarily in a memory in the form of an intermediate code which can be converted into executable machine code in runtime. The method includes the steps of providing a modified program or a modified program module, also in the form of an intermediate code, and comparing the intermediate code of the modified program or that of the modified program module with the intermediate code of the running program for determining the modifications, and implementing modifications to the running program. A correspondingly adapted run-time system is also provided, which is suitable for implementing the procedure as well as the integration of this run-time system into an automation facility.

Abstract: The invention relates to a method and an apparatus for safe parameterization in accordance with IEC 61508 SIL 1 to 3 or EN 954-1 Categories 1 to 4 of safe electronic appliances. One object of the invention is to describe a way which overcomes the explicit reading back of the parameters from the safe electronic appliance and confirmation of each of these parameters by the user. For this purpose, the invention proposes that parameter values which are intended for parameterization, are selected or entered via a user interface of an electronic control device and are then transmitted to the electronic appliance, to be kept in at least one memory which can be accessed by the control device, and be read back at least once from the memory for verification of the safe parameterization.
