摘要
AS-i网络技术实现了底层工业自动化领域传感器、执行器的数字化与网络化,以S7-200 PLC为主控制器的AS-i网络系统,是底层简单网络系统的优秀解决方案。S7-200 PLC AS-i网络系统硬件设计的关键是网络布局与AS-i网络电源负载能力核算;软件设计的关键是在S7-200 PLC中编程,实现周期性数据与非周期性数据的传输。
AS-Interface system realized the digitization and networking of sensors and actuators at the lowest industrial automation field level, and based on the controller of S7-200 PLC, it is the best solution of the lower simple network system. The key of hardware design of S7-200 PLC AS-Interface system is to distribute network and to account load capacity of AS- Interface power. The crucial point of software design is programming in S7-200 PLC to realize the transmission between periodic and aperiodic data.
