摘要
阐述了一种基于Modbus的多现场总线测控系统集成方法。在分析Modbus协议的基础上,设计了一种具有测控功能的多协议转换装置,并将西门子和欧姆龙公司的PLC网络集成到Modbus测控系统中。针对小型汽轮发电机系统,构建了基于多种现场总线的测控系统,并验证了整个系统设计的可行性。该多协议转换装置为原有设备的系统改造提供了一种高效的解决方案。
The integrating method of a Modbus-based measuring and control system with multiple fieldbus is expounded. On the basis of analysis on Modbus protocol, the conversion device for multiple protocols is designed, and the device features measuring and control functions. And the PLC systems from Siemens and Omron are integrated into Modbus measuring and control system. Aiming at the small scaled steam turbine generating system, the measuring and control system based on multiple fieldbus are structured ; and the feasibility of the whole system has been verified. Thus, the protocol conversion device provides effective solution to system retrofit of existing old equipment.
