netPI as OPC/UA-Client
#1
Welche Möglichkeiten gibt es, netPI als OPC/UA-Client zu betreiben (um z.B. mit einer S7-1500 oder AB zu koppeln)?

Free Python OPC UA client or Node-RED OPC UA client node...

Thx

By the way, if you want to read from S7-1500/1200 there is no need for OPC UA client function.

There is node for Node-RED that reads variables from an S7 PLC directly: https://flows.nodered.org/node/node-red-contrib-s7comm

Pull original Node-RED image maintained by Node-RED organization on your netPI. The official Node-RED Docker web site is here: https://hub.docker.com/r/nodered/node-red-docker/.

Node-RED Docker images are available for different CPUs. One image is made for Raspberry Pi compatible devices tagged as name rpi-v8 for node.js in the version V8 as basis. So pull the image nodered/node-red-docker:rpi-v8

Start a container from the imaged and map port 1880 as described in the repository. After started standard Node-RED includes the "Manage Palette" function. Use it and search for node named node-red-contrib-s7comm and post install it.
