Hi!
I have a Schneider PLC that runs CodeSys 3.5 and a Weintek HMI (easybuilder pro software). The HMI is accessing the variables in the PLC by importing the xml-file with symbol information from symbol configuration that the PLC program generates when i do a build. This is working fine and all I specified in the HMI was that it's Codesys V3 (Ethernet) and the IP address. (the port was automatically 1740 and source port 1742 and there is a option that is set to UDP).
I also want to access these variables from Node-Red but i cant find any information on what protocol is used. Is it some kind of OPC UA? Schneider support does not seem to give any support in this matter.
If you would like to refer to this comment somewhere else in this project, copy and paste the following link:
