Description

technical field [0001] The invention belongs to the technical field of industrial control, and specifically discloses a method for generating on-site measurement point simulation data of an industrial control system and a system using the method. Background technique [0002] Industrial control system network communication simulation is the main method for industrial control system equipment debugging, especially for system host computer software testing and debugging. The upper computer software of the industrial control system usually needs to collect the health status data of the whole system for interface display and to issue closed-loop control instructions according to the collected health status information. Since the upper computer needs to collect health status data from all equipment in the whole system, there are many external network communication interfaces, and software testing and system debugging are highly dependent on the environment. Usually, the upper com...

Problems solved by technology

[0005] Versatility issues: For each different industrial control application scenario, different communication debugging codes need to be customized and developed. There is a lot of duplication of labor, and the reuse of communication debugging codes cannot be achieved.

[0006] Batch problem: using the debugging assistant can not simulate multiple device communication on a single machine; customizing the development of communication debugging code is heavy workload, long time period and not universal

[0007] Flexibility problem: the above methods can only meet the simulation needs of fixed data communication, and it is difficult to meet the needs of flexible and changing data communication. Certain mathematical formulas and other requirements
