| Abstract: | Aiming at problem of interface design between specific controllers and DCS system in power plant,the basic method how to expand communication interface between TCS-3000 DCS and third-party equipments is considered,the serial communication network based on the Modbus protocol was realized,the technical problem how DCS system read reliably data from the specific controllers based on S7-200 PLC with serial communication is resolved,the experiment has verified that the method has the characteristic of reliability and stability,and can be popularized in engineering practice. |
| Keywords: | TCS-3000 S7-200 Modbus protocol serial communication |
