| Abstract: | Modhus communication system was developed by using C# programming language, which took tempera- ture and humidity acquisition system as an example. Slave machine was temperature and humidity testing modules with Modbus communication function. Multiple modules were connected via bus 485, and the communication bus was connected to a PC serial port though RS232-RS485 converter. System software accessed each module with Modbus protocol. Thus multi-point temperature and humidity acquisition was achieved. |
