摘要： A method for operating a programmable logic control device to which a current input data set having state data regarding a peripheral component is provided cyclically by a communications bus after each bus cycle terminates. A first program instance of a control program is cyclically processed by a control device. The program cycle duration is longer than the bus cycle duration and, therefore, between the beginning and end of the program cycle, the communications bus provides at least one current data set that cannot be taken into account by the first program instance. To reduce the latency with which a control device reacts to a change in the input value of a peripheral component. at least one other program instance of the control program is cyclically processed so that it is temporally offset by less than one program cycle duration relative to the first program instance.

摘要： A method for regulating process, production, and/or actuating installation includes recording observation data records at installation components of the installation by respective recording units of the installation. The method also includes transmitting the observation data records to a central control apparatus of the installation via a field bus. The method further includes forming, at the control apparatus, associated actuating data record based on the transmitted observation data records. The method also includes transmitting the actuating data records to actuating units of the installation via filed buses. The method also includes adjusting the installation components from the actuating units based on the transmitted actuating data records. The observation data records are encrypted at the respective recording units before transmitted to the control apparatus The actuating data records are formed from the encrypted observation data records without decrypting the encrypted observation data records during the process of forming the actuating data records.

摘要翻译：一种用于操作可编程逻辑控制装置的方法，在每个总线周期结束之后循环地由通信总线提供具有关于外围组件的状态数据的当前输入数据组。控制程序的第一程序实例由控制装置循环处理。程序周期持续时间长于总线周期持续时间，因此在程序周期的开始和结束之间，通信总线提供至少一个当前数据集，该数据集不能被第一程序实例考虑在内。为了减少控制设备对周边组件的输入值变化做出反应的延迟。控制程序的至少一个其他程序实例被循环地处理，使得其相对于第一程序实例在时间上偏移少于一个程序周期持续时间。
