Siemens PLC, being as mainstream automatic control system, at present is widely applied in in-dustrial field. The article introduces a situation in which one communication module will be equipped in Siemens S7-300 PLC master station, connected to other external machines, to form one local network in in-dustrial field, by PLC-S7 software such functions can be realized as modifying data in control system, moni-toring machine in real time, checking failures. The article puts emphasis on introduction for analysis over is-sues like collision of robot during operation process, reciprocal interlocking of signals, acknowledge between machines, and also introduction for how to use PLC-S7 software optimize program to eliminate the failure fi-nally, so that the maintenance cost and breakdown rate can be reduced, and productive rate can be in-creased. All of those shows that the Siemens PLC has characters such as convenience, stability, easy mainte-nance and so on in industrial application.
