Beschreibung
Zusammenfassung:	The invention discloses a detection method of a PLC and an IO extension module. According to the detection method, a direct-current power supply provides a working power supply for a PLC and an IO extension module by an over-current protection fuse; and the PLC and a PC machine are connected for communication by a communication cable. 24-path digital output ports of the PLC are respectively connected with 24-path digital input ports of the PLC; and four-path analog output ports of the PLC are connected with eight-path analog input ports of the PLC and each path of analog output port is connected with two paths of analog input ports. A COM1 port and a COM2 port of the PLC are connected by an RS232 plug; and a CS31 communication port of the PLC is connected with the IO extension module by a CS31 bus.
