Abstract

The invention provides a PLC software programming aided design method. The PLC software programming aided design method comprises a step 1 of receiving a table stored with specific parameters of a PLC software function module, the specific parameters being used for automatically and regularly generating correlated variables and finally generating PLC codes; a step 2 of enabling PLC programming auxiliary design software to automatically generate a variable identification external input-output signal list of external input-output signals; a step 3 of enabling the PLC programming auxiliary design software to generate internal intermediate variables and PLC program codes; a step 4 of introducing generated internal variable information and calling codes into PLC programming software. The PLC software programming aided design method is advantaged in that the PLC programming process is greatly simplified, errors, of codes and parameters, caused by manual input are avoided, variable names, annotation, storage regions and the like which are automatically generated all accord with the standardizing programming requirement, the fact that the generated PLC codes are from an unified module library can be ensured, and the fact that the PLC program architecture is standardized is ensured.

Description

technical field

[0001] The invention relates to a method for realizing PLC software programming aided design by adopting self-compiled tool software. The invention can be widely used in the programming of the programmable controller (PLC) software platform supporting the text programming language in the field of industrial automation. Background technique

[0002] In the PLC programming process, it is necessary to determine the control logic according to the operation mode of the controlled equipment, and then select the corresponding programming instructions and fill in the appropriate variables to complete the logic control program. The software variables include the external variables from the input / output signals of the IO module, as well as the internal intermediate variables used in the logic operation of the program. The naming of these external IO variables and internal intermediate variables, the determination of the PLC storage address, and filling in the correspo...
