摘　　要：根据控制器网络组网方式,并结合其通讯标志位和PLC编程,设计能够由系统主站决定网络中任意一台系统子站的"联网"与"本地"的工作模式,以及当系统子站断开与主站的连接或未接入网络中时,自动切换成"本地"模式的功能。According to the networking mode of Controller Link network, combined with its communication flag bit and PLC programming, this paper proposes a new mechanism that the working mode of "networking" and "local" can be determined by the system master station. Furthermore, the system can switch to "local" mode automatically when the sub-station of the system disconnects from the main station or is not connected to the network.
