Post by damian177 on Problem with downloading OPC UA tags by Data Source Manager ^{CODESYS Forge talk (Post)}
Hi, In Codesys V3.5 SP20, using Data Source Manager I am trying to connect to the OPC UA server and receive tags from it. The connection is ok, but the Codesys have a problem with downloading Tags group. The window (downloadingTags.jpg in attachement) never stop. After waiting for a while, I disconnect the connection and only the Server group remains downloaded, with OPC UA server diagnostic data (and this is read in Codesys). Of course, I tried connected via another OPC UA client : UaExpert , and everything works as it should, all tags are downloaded (Uaexpert.jpg screen). Has anyone on the forum encountered the OPC UA client configuration in Codesys? Is it possible to manually request the appropriate tags from the OPC server for reading in Codesys?

Post by askjong on Update variables when OPC UA Client updates. Error ID: 268468277 BadAttributeIdInvalid ^{CODESYS Forge talk (Post)}
Hi, I'm connecting to a OPC UA Server using the Data Soruce Manager OPC UA Client. This works well until the OPC UA Server updates and the OPC UA list doesn't match up when i did last clicked the "Update variables" to add variables. All the variables are still the exists and none are removed from the server, but more are added during the engineering process. The error message i get in CODESYS is "Error in OPC UA call BadAttributeIdInvalid, Error ID: 268468277". The issues is fixed when i press the "Update variables" button and just press ok without adding or removing any variables in the list. Is there a way to either automatically update the browsepath if it fails or on startup, or to trigger it by code?
