Post by ofey on Codesys Soft PLC OPC UA server ^{CODESYS Forge talk (Post)}
Hi! I'm sorry if this has been asked before. I have tried looking up previous topics regaring this, but even though I'm following tutorials and other posts I cant seem to get this to work consistently. I actually got the connection established on a test project after some trial and error. I only got it to work with the "Anonymous login". But after i deleted the test project and tried to get the same thing to work on another project I cant get it to work anymore. What I'm trying to do: Set up and OPC UA Server using CODESYS with the free soft PLC. I then try to connect to the OPC UA Server with the program "UaExpert". What happens: I get the error Error "'BadUserAccessDenied' was returned during ActivateSession". What I have done in CODESYS: - Added the object "Symbol configuration" and checked some test variables - Checked "Support OPC UA features - In "Communication settings -> device -> Change runtime security policy" I have checked "Allow anonymous login" What I have done in UAExpert: - Found the OPC UA server under "local". (It is showing two servers though, I do not know why. It showed the same when it worked yesterday). Se attachment - Checked "Anonymous" under "Authentication settings in the OPC UA server. I'm new to CODESYS, so it could be something elementary wrong in my settings. Maybe something in the user settings in CODESYS regarding user rights or something?
