Embodiment Construction
[0037] Such as figure 1 Shown, the detection method of O point communication scope of the present invention, comprises:
[0038] Step S1, traverse the engineering equipment table (such as DDB01 table), find out all control station equipment in the engineering equipment table, and read the subscript data corresponding to all the control station equipment from the subscript corresponding table (such as SuffixTable) (such as SIM_suffix.txt), to obtain the communication range of IO points of different data types of all control station equipment and save them in the control station information array;
[0039] Step S2, traverse all control stations in the control station information array; each control station traverses in the order of control station-rack-module-process equipment-process IO points; usually all IO points in the system are in accordance with "control station- Rack-module-process equipment-process IO points" are managed hierarchically, so when traversing in this orde...

The present invention provides an IO point communication range detection method. The method comprises: the step S1, traversing an engineering device table, finding out all the control station devices in the engineering device table, reading subscript data corresponding to the control station devices from a subscript corresponding table, obtaining the communication ranges of IO points with different data types of the control station devices, storing the communication ranges of IO points into a control station information array; the step S2, traversing all the control stations in the control station information array; the step S3, finding an IO point capable of switching on a communication switch or a value writing switch in each control station, and obtaining the information of the IO point; and the step S4, comparing the information of the IO point with the communication ranges of the IO points with different data types of the reading control station device, and determining whether the IO point exceeds the communication range of the control station or not. The present invention further provides a plugin capable of executing the method mentioned above and a computer readable medium comprising the plugin. The IO point communication range detection method and plugin, and the computer readable medium can check all the communication IO points exceeding the range so as to ensure that all the IO points of the current engineering is located in the communication range of the actual control station.
Description
technical field [0001] The invention relates to the technical field of industrial control, in particular to a method for detecting IO points beyond the communication range in complex system engineering, a plug-in and a computer-readable medium. Background technique [0002] In the field of industrial control technology, the current software does not detect and judge the range of communication IO points in the project. As a result, when the communication IO points exceed the communication IO range of the actual control station, the excess part cannot communicate normally. When the project is more complicated, check The problem is more difficult. [0003] The following is an explanation of several concepts in the field of industrial control technology: [0004] (1) Engineering equipment table, which is used to store all engineering equipment information of the system, and its actual size is selected and determined when the project is created. [0005] (2) Engineering equipme...
