Post by bbm1995 on Security Screen - Custom Certificates for OPC UA Server? ^{CODESYS Forge talk (Post)}
Hi everyone, is it possible to use selfsigned/created certificates (eg. with X - Certificate and Key Management) as a OPC UA Server certificate in the Security Screen? As far as I know I can only upload client certificates to the PLC and move it to "Trusted", "Untrusted" and "Quarantined". Same question is on sps-forum.de

Trying to create a Data Source under Data source manager, but I'm having issues with security. I get "BadUserAcessDenied" I don't know if there is something special I need to do on the Kepware server to make this work or what.

I have not used this client / server OPC UA combination since. We were only making some kind of proof of concept. I did understand that there could be some kind of bug. I do not know if the supposed bug has been resoved since. Perhaps you could try what piautomation is suggesting

Post by stiller on OPC UA RPI 4.8.0.0 Status Code / "out of range" ^{CODESYS Forge talk (Post)}
Hello, I have an OPC-UA server with an information model. For many values, there is a defined range (e.g., 0 to 100). If a client enters a value outside this range (e.g., 120), the StatusCode should change to Bad. How can I accomplish this? Any help is appreciated! Thank you in advance. Best regards, Christian Stiller

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?

Post by nizrahel on OpC UA server on Raspberry Pi 64 SL runtime ^{CODESYS Forge talk (Post)}
Hi all! I'm working on an home project using a Raspberry Pi 3 device with Codesys for Raspberry Pi 64 SL runtime. I would like to create the HMI interface with Siemens WinCC Unified (or Advanced) configuring the Raspberry as OPC UA server. I tryed everything, but I didn't find the way to let the OPC UA connection works using UaExpert. I tryed to use anonymous connection, authenticated connection and the ip address instead of the server name in the path connection. There is no way to connect to the OPC UA server and I was asking myself if this feature is really supported for the runtime version used. Another strange thing I noted, is that is not possible to quickly create an OPC UA certificate in the Security Screen, as show in any tutorials. I have correctly created the Symbol Configuration enabling the OPC UA feature. I attach to this topic some printscreen of the actual configuration (sorry for the italian language interface, but I didn't find the way to switch to english). Thank you very much in advance for your support and advices!

Post by dogulas on OPC UA C# client connecting to OPC UA CODESYS server ^{CODESYS Forge talk (Post)}
Noob alert! I’m just getting my feet wet with CODESYS. I have a “Hello World” project in the CODESYS IDE. I’m using the Win SoftPLC on the same computer. I’ve added a Communication Manager under the Application node. Under that is “OPC UA Server -> IEC Symbol Publishing 01”. I also added “OPC_UA_Symbols -> Information Model”. I’m not sure I need the second thing. I was grasping at straws. I also set up several dummy symbols in the IEC Symbol Publishing 01 node. In my C# application, I am trying to get an instance of EndpointDescription from CoreClientUtils.SelectEndpoint(“opc.tcp://localhost:1217/Gateway-1”, useSecurity: false, 15000). I wasn’t sure about the “Gateway-1”. I found that in the CODESYS IDE under the project -> Communication Settings. When I execute the previous method call in C#, I get: “BadSecureChannelClosed”. I have no idea what that means. Any pointers to documentation are welcome.

Post by expertplas on No connection to opc server from codesys opc client ^{CODESYS Forge talk (Post)}
Hello, we have aproblen to connect our CODESYS OPC Client to the OPC Server. We installed the client according the CODESYS manual. We can browse the server and variables can be linked to the PLC. I created a self signed certificate for the CmpOPCUAClent as described. The server has a cerificate also. I copied the certificates to the trusted zone of server and client. But when it comes to data exchange we get an error message. "Communication error in data source OPC UA Library. Error ID : 7001 German : "Kommunikatinsfehler inder Datenquelle OPC UA -Bibiothek. Es wurde kein genauer Fehler angegeben. Fehler ID : 7001" It semms that there is no cerificate exchange. We are working with CODESYS 3.5 SP19 Patch 5. Can anyone here say something about this error or has an idea for a solution? Thanks.
