Post by msegon on OPC UA Client failed to connect ^{CODESYS Forge talk (Post)}
Hi everyone, I would appreciate your help with a problem I've been working on for a few days but haven't been able to resolve. I'm trying to read data from Tridium Niagara 4.15 OPC UA Server, but I get the error BadCertificateInvalid. As far as I understand, you need to add a CA certificate somewhere to establish a secure connection, but I don't know where. 2025-10-27T09:06:43.247Z, 0x0000008d, 4, 0, 0, * ERROR: OpcUa_Channel_BeginConnect: Cannot create secure channel without certificates! 2025-10-27T09:06:43.247Z, 0x00001090, 4, 0, 0, * ERROR: Datasource: Error Failed (268468242) in state Connecting I tried communicating without encryption, but it doesn't find the point. Has anyone managed to establish encrypted OPC UA communication?

Post by tk096 on Motion FB Error ^{CODESYS Forge talk (Post)}
Hi, Softmotion Robotics does not support tracking in/out to dynamic coordinate systems with relative movements. Is MC_MoveLinearAbsolute an option? See SMC_RELATIVE_MOVEMENT_TRACKING_CS in https://content.helpme-codesys.com/en/libs/SM3_Error/Current/SM3_Error/SMC_ERROR.html Concerning the other error: Do you use any motion function blocks of SM3_Basic to move a single axis of the robot in your application?

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Post by vformanek on Datasource OPC UA Client error ID:7012 ^{CODESYS Forge talk (Post)}
Hey, I am facing the same problem. Basically UA Expert and other programs work fine with the login credentials. But codesys can not use them properly. I can see the server login to it manually but when I download the program and run the datasource never runs... Currently I am facing the same Error ID: 7012 and cant get it running properly.
