Abstract: | When we use profibus-DP bus it is frequent with the PLC control system. Once the communication module of DP master-slave station fails, the whole control system will out of control. This paper mainly introduces a method of using LabView and OPC server instead of DP slave station, Which the control system can still work properly, even if master-slave station module is missing. |
