一种PLC程序控制逻辑的检测装置
摘要：
本发明涉及一种PLC程序控制逻辑的检测装置，包括模式选择模块、控制器以及输入状态指示模块，模式选择模块连接控制器的模式选择输入端口；控制器的输出端口用于连接下载有待测PLC程序的待检测PLC设备以触发待测PLC程序；输入状态指示模块的输入端口用于连接PLC检测设备的输出端口以显示待检测PLC设备中待测PLC程序的输出状态。本发明通过模式选择模块以及控制器内部程序编程，选择执行不同模式下的触发信号，并将该触发信号输出到下载有待检测程序的PLC设备上，以此触发待检测PLC程序的逻辑功能，然后将PLC设备的输出引入到检测装置的输入状态指示模块，通过观察输入点对应的输入状态指示模块中指示灯的变化来完成对PLC程序逻辑功能的检测。
摘要（英）：

The invention relates to a PLC programmed logic detection device. The PLC programmed logic detection device comprises a mode selection module, a controller and an input state indication module; the mode selection module is connected to a mode selection input port of the controller; the output terminal of the controller is used for connecting to a PLC device to be detected , on which a PLC program to be detected is downloaded in order to trigger the PLC program to be detected; the input port of the input state indication module is connected to the output port of the PLC detection device in order to display the output state of the PLC program to be detected in the PLC device to be detected. The PLC programmed logic detection device selectively executes triggering signals under different modes through the mode selection module and programming inside the controller, outputs the triggering signal to the PLC device, on which the program to be detected is downloaded, in order to trigger a logic function of the PLC program to be detected, guides the output of the PLC device to the input state indication module of the detection device and completes detection on the PLC program logic function through observing the change of an indication lamp in the input state indication module corresponding to an input point.
