| Abstract: | This paper introduces a control system which has the property of cost-effective multi-channel temperature detection. The system is based on Modbus protocol, taking ST-200PLC as master station and SST-16RTD type thermal resistance input components as slave station under the master-slave mode for real time temperature data transmission, to achieve the heating system＇s temperature control and data display. The paper shows the realization of system＇s software and hardware. The system has been used in a number of practical engineering applications successfully. |
