摘要
针对PLC逻辑功能测试的不完整性问题,本文提出一种PLC逻辑功能测试完整性可量化的方法。首先,建立PLC逻辑功能和功能块的测试例子库。在编写PLC逻辑功能测试例子时,通过调用逻辑功能测试例子库中相应的模板,编写出完整的逻辑功能测试例子。最后,通过编写一个PLC逻辑功能测试例子,验证了该方法的有效性。
Aiming at the not complete problem of PLC logic function test, the paper proposed a quantized complete method of testing PLC logic function. Firstly, a test case library of PLC logic function and function block was established. While we edit PLC logic function test case, the complete logic function test case was edited by use of models in the logic function test case library. Finally, the method was verified through editing a PLC logic function test case.
