WebModbus是一种串行通信协议,是Modicon公司(现在的施耐德电气 Schneider Electric)于1979年为使用可编程逻辑控制器(PLC)通信而发表。 Modbus已经成为工业领域通信协议的业界标准(De facto),并且现在是工业电子设备之间常用的连接方式。 modbus入门请参考: http://www.elecfans.com/rengongzhineng/596297.html 1.2. 主机例程 ¶ 首先来看一 … Web- UART interface : Modbus RTU slave communication support for talking to other devices acting as Modbus RT master over RS485 network - …
一种用于SIS系统的通讯冗余机制【掌桥专利】
Web本发明公开了一种用于SIS系统的通讯冗余机制,实现通讯冗余,在其中一条线路发生故障时,其他线路还可以正常工作,实现多网口冗余,可灵活配置,某种冗余模式下,可以跨模板,多种冗余下互不影响,如modbus TCP和RTU冗余链路互不影响,各自管理各自的通讯链路,具有一定的使用价值和推广价值。 Web1 nov. 2024 · The Modbus command appears well formed when viewed via Wireshark.
