首先,你需要确认你的西门子PLC型号与Node-RED的兼容性。大多数现代的西门子PLC(如S7-1200、S7-1500等)都可以通过特定的通信协议(如S7通信协议)与Node-RED进行通信。 在Node-RED中安装必要的节点以支持西门子PLC通信: 你需要在Node-RED中安装支持西门子PLC通信的节点。通常,这可以通过Node-RED的节点管理器(Node-RE...
下文将介绍如何使用Node-RED通过MPI-131模块获取S7-300 PLC数据。 以下是具体的实现步骤: 首先,需要提前安装好Node-RED程序,进入Node-RED的配置界面,点击侧边的菜单,选择“Manage palette”,选择安装contrib-S7 module模块。 在“Install”区域搜索S7,然后安装node-red-contrib-s7 module模块。 安装成功之后,您可以看...
Some PLCs, like theSiemens S7 PLC, can connect to the cloud without needing an external gateway. For example, when paired with aCP 1543-1orCP 1243-7 LTEmodule, the Siemens S7 can interact with cloud platforms using Internet-friendly protocols. This direct connection simplifies the setup and...
