Post by alimans on OPC-UA Server, Symbol Set: Raise an error: Object reference not set to an instance of an object. ^{CODESYS Forge talk (Post)}
Hi everyone, I just created a very simple library without any code and, added it to my very simple project. after adding this library, I get an error when I try to open "Symbol Set" in "OPC UA Server" in "Communication Manager". Here is the code of my POU in the library: FUNCTION_BLOCK POU VAR eCommand : (CMD_NONE:=0, CMD_RESET:=-1) INT := CMD_NONE; END_VAR Attached is the error that I get. I also noticed that by removing the enumeration variable above (eCommand), I can open the "Symbol Set" again. Anybody has any idea why this error is raised and how could I use enumeration variables without error in "OPC UA Symbol Set"?

Post by yannickasselin on codesys VLAN tagging ^{CODESYS Forge talk (Post)}
Hi, I am looking for exactly the same thing. I would think that using a layer 2/3 managed switch should work but I am not convinced. I would like to test it in order to see if it would be possible to run many Codesys Docker instances on a server and run only 1 ethernet cable from the server to a managed switch closer to the machines beeing controlled instead of having to run multiple long ethernet cables. I was going to buy a managed switch in order to test it but I want to first make sure it is possible and I want to figure out exactly what kind of switch I would need. Is this even possible? I think this is a feature that would be very useful paired with "Codesys Virtual Control SL". Thank you

Post by matt-purcell on Which Lib to use, connect to a socket with URL instead of IP address ^{CODESYS Forge talk (Post)}
Hello, I have a new project and I need to connect to a TCP socket using the URL instead of an explicit IP address, myendpoint@mydomain.com Which library is best suited for this? This is for a new enterprise project, the endpoint is a server in a datacenter running some real time application. We have big IP, it will automatically reassign the IP address to the backup server if a crash occurs so an explicit IP won't work for me. I've done this in RS logix, working now to migrate that code over to codesys. Thanks in advance!
