| Abstract: | In order to improve the efficiency of PLC numerical processing program design,based on the principle of computer expression evaluation,a numerical processing algorithm for PLC is designed.Mitsubishi PLC modular program structure SFC is designed by using the technology of index register,to achieved automatic addressing in the process.The judging method of cycle analysis is designed to achieved automatic addressing in the process.The judging method of cycle analysis is designed,the numerical processing module program is completed,and the main points of algorithm programming realizing is presented.This program can simplify arithmetic expression programming,and it is convenient for secondary development.It can be reused to achieved floating point numbers calculation,which simplifies the programming difficulty of designed algorithms for PLC processing control. |
