摘要
从S7-200系列PLC定时器最优化设计的角度出发,阐述了以控制网络、指令盒、状态位输出三个基本网络作为定时器设计规范,以及定时器的定时、复位和网络结构的具体情况,三网络结构具有网络结构清晰,网络功能确切、程序的可读性强等优点.
The article describes the most optimization design of PLC timer, focusing on the criterion of timer design in the aspects of dominating network, dictating box and state output as well, while the timing, returning and network structure of the timer are also introduced. The three network structures feature as simple structure, reliable function and easy-understood programming.
