Problems solved by technology
However, the program execution task will change the processing time due to the addition and modification of program logic and the execution of different program logic branches.
[0004] In order to adapt to the changing processing time of program execution tasks, engineers need to manually adjust the scan cycle of the control system to ensure that the system load is lower than the threshold (generally the threshold is set to 50%), the process is cumbersome and the efficiency is low

The embodiment of the present application discloses a configuration method and related equipment for controlling the scanning period of the system. After the control system configures the scan period, it can configure the preset processing duration of the program execution task according to the scan period. The control system records the processing time of the running program execution task, and compares the processing time of the program execution task with the preset processing time. When the processing time of the program execution task reaches the preset processing time, the control system automatically increases the scan cycle, and configures a new preset processing time according to the new scan cycle. The control system re-records the processing duration of the program execution task until the processing duration of the program execution task is less than the preset processing duration, then it is determined that the currently used scanning period is the target scanning period. In the process of adjusting the scan period, the invention does not require engineering personnel to manually adjust, thus improving the efficiency.
Description
technical field [0001] The embodiments of the present application relate to the technical field of industrial automation, and in particular to a method for configuring a scan period of a control system and related equipment. Background technique [0002] When the equipment is in the factory acceptance test (FAT, factory acceptance test) stage, engineers need to design the process configuration of the control system of the equipment and debug the scan cycle of the control system. In order to obtain a better response effect, in the initial stage, generally configure a smaller scan period for the control system. However, while configuring the scan cycle, the system load also needs to be taken into consideration. Engineering execution specifications generally require that the system load be lower than 50%. [0003] Generally speaking, in the control system, the ratio of the processing time of the real-time task to the scan cycle is the system load of the control system. Real-t...
