Good Morning I'm having a lot of difficulty in an industry 4.0 implementation project my structure and the following. CPU S7300 (SIMATIC MANAGER<-> IOT2040 (PUTTY AND RED NODE)<->OPC UA(UA EXPERT) S7300 CPU (SIMATIC MANAGER<-> IOT2040 (PUTTY AND RED NODE) IS OK. Already able to carry out the communication and data exchange between the PLC and the IOT2040,Through the putty I did the installation of the NPM INSTALL NODE -RED-CONTRIB-S7 package. It worked and everything is ok. NOTE my IOT is communicating with the internet (I can ping google.) IOT2040 (PUTTY AND RED NODE)<->OPC UA(UA EXPERT) I'M HAVING PROBLEMS WITH COMMUNICATION. Now my problem is related to the communication between the IOT2040 and the OPC UA. I did the same procedure to install the NPM package INSTALL NODE-RED-CONTRIB-OPCUA the installation and completed with version 0.2.236 apparently this ok. However, when I go to configure the OPC UA on node red through the web it generates a failure for me (image 1). I noticed that when I go to check packages through PUTTY with the -g --depth 0 command the same appears in version 0.2.236 (image 2) However, when I go to check the packages through the WEB through manage pallete the package is in version 0.2.88 theoretically a more updated version, but according to the node red website this version doesn't even exist. (https://flows.nodered. org/node/node-red-contrib-opcua as per (image 4). Below is a photo of my current structure (image 5) I'm in doubt where I'm going wrong. Whether and in version incompatibility? Did I install the right package in putty? Do I have to enable something within WEB NODE RED access to update the OPC UA package? If there is any configuration I have to do in WEB NODE RED for OPC UA? In fact I'm a bit lost and I need help has anyone done any similar settings? Is there any procedure you can send me?

Hello, Its because the nodes are installed in two different locations. Can you try updating them over Manage Palette -> Install -> Search for node-red-contrib-opcua alternatively you can run the npm install command again in
if you are still unable to use the nodes, I would recommend removing the installed packages and installing a specific version 0.2.33 which we have tested in our application Example "DataCollector Node-Red".
Also not to forget, these nodes are deprecated, but could be an alternatice solution. A different problem I see with this usecase on the other hand, is that we had experienced some crashes of v8 engine in the past when using the opcua server nodes in node-red for various hours. Alternatively an OPC UA Server in pure nodejs could be used, example: https://support.industry.siemens.com/tf/ww/en/posts/190674/ BR |
