AI Technical Summary
Technical Problem
Existing PLC program testing methods require manually writing ladder diagrams, which incurs compiler conversion overhead and hardware device dependencies, and cannot simultaneously call multiple hardware devices for testing.
Method used
By obtaining the test description files of PLC functions, parsing and forming compilable program files, and using function test templates to generate test results, the dependency on compilers is reduced, and software-level testing is achieved.
Benefits of technology
It can automatically test the correctness of PLC functions without the need for hardware equipment and network communication support, reducing compilation overhead and supporting simultaneous testing of multiple PLC functions.

Abstract
本申请公开了一种可编程逻辑控制器程序的测试方法、装置、设备及介质。该方法包括：获取相对至少一个待测可编程逻辑控制PLC函数预先编写的测试描述文件；按照设定解析规则解析测试描述文件，获得各待测PLC函数的待测函数信息；基于各待测函数信息结合预设的函数测试模板，形成可编译程序文件；基于对可编译程序文件进行编译及运行后的运行结果，确定各待测PLC函数的函数测试结果。通过该方法，测试人员只需要输入测试描述文本，解析测试描述文件，通过预设的函数测试模板自动生成可编译程序文件，无需额外编译器，达到减少编译开销效果；本方法运行在软件层，解决了硬件支持及其相关的网络通信问题，实现了无需硬件设备也能对PLC函数正确性进行测试。
