摘要
设计了基于S7-300系列PLC和力控组态软件的油库罐区监控系统,介绍了其硬件结构和软件设计。该系统通过工业以太网实现上位机和PLC的通信,采用上位机双机冗余和PLC软冗余结构,可以充分发挥PLC和计算机的优势,有助于提高监控系统的可靠性。
The oil tanks area monitor system based on PLC S7-300, configuration software and the design of hardware and .software are introduced in this paper. In this system, Superior computers communicate with PLC through industrial Ethemet. The superior computers system adopts duplex redundancy technology and the PLC software redundancy technology to take full advantage of PLC and computer, which can improve the reliability of the monitor system.
