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?

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?

it could be due to security settings. In codesys IDE, go to device-> change run-time security policy, and click the checkbox that says "Allow anonymous login". try if this works.

Post by esave on OPC UA Server with on Codesys + OPC UA Client on Labview ^{CODESYS Forge talk (Post)}
Hello everyone I want a communication between my PLC as an OPC UA Server and Labview on my PC as the OPC UA Client. I have an Festo CPX-E-CEC-C1-PN PLC and I have the OPC UA Toolkit from Labview. I created some Variables for testing (see picture 1) on Codesys. I tried to use this Labview block diagram (see picture 2) but I cant connect the PLC to it. What do I have to type in the Server Endpoint URL and what in the Node ID? Is this a good way for communication with a PLC to a PC? If not is there another way?

Post by bjarne-pagaard on OPC UA Server Status on Win RTE ^{CODESYS Forge talk (Post)}
Hi there, An "OPC Expert" client software is connecting to a Codesys Control RTE (x64) OPC UA Server. It reads only about 25 variables every 5 minutes. The OPC UA Server seems to shut down on the Codesys runtime. Is there any way to get information about the Codesys OPC UA Server status? Restart it? There is nothing in the PLC Logs after the OPC UA Server has started. It works for a while, then it doesn't. Any ideas? Any way of getting more info out of the Codesys OPC UA Server? -Bjarne

Post by thn-power on How to change OPC NodeId IdentifierType ^{CODESYS Forge talk (Post)}
Hi Yet another OPC UA question. When setting up a OPC server using "Communcation manager" (Symbol set and information model) in Codesys the NodeId is always given as "opaque" type. At least when browsing using UAExpert. Other standard OPC objects use numeric (or string) identifier, but for some reason my variables seems to get opaque/binary type. See attached photo. How can I change this? I can't see that this is a parameter in the CodesysControl.cfg. Can this be specified in the information model nodeset? And is it possible to specify the exact numeric or string NodeId for each instance? And on a related topic, is there a way to export the OPC server nodeId's with variable name so that it can be imported in a OPC Client? The .xml files in the project folder does not seem to contain the NodeId.
