| Abstract: | The asynchronous serial communication was used between WB intelligent senor and S7-PLC, its information was distributed through COM port of S7-200 PLC and RS485 port of WB Intelligent sensor. The communication was realized with the protocol of WB Sensor and the programming of the S7-200 PLC CPU. The programming of S7-200 CPU consists of the initialzation, reading command, writing command to WB intelligent Sensor, 0 character receiving program of interrupting eight ports, returning data and data processing. The communication was applied in the parameters test system of air condition. |
