Abstract (en)
[origin: WO2020074650A1] The invention relates to a method for optimizing data processing in a programmable logic controller (PLC). The PLC has a control task, which comprises a plurality of executable programs. At least two programs of the control task each have at least one parallel processing portion having a work package having a plurality of sub-tasks. The parallel processing portions in the respective programs are assigned a priority having a specified priority level. The particular priority levels are inserted into a data structure as soon as execution of the program has reached the parallel processing portion. At least one parallel processor core checks if there are entries in the data structure and, if there are entries, said parallel processor core completes sub-tasks from the work package of the program that has a priority level in the first position of the entries in the data structure. During a program cycle, an expected computing throughput of the control task is continually evaluated and at least one of the priority levels of the parallel processing portions of the respective programs is dynamically modified if the computing throughput of the control task is increased thereby.
