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?

Hi. As far as projects in "old version"s are concerned, these can be upgraded to newer versions at any time. To do this, the device must be updated accordingly and the copilers and library versions must be adapted. You can find instructions on how to proceed in the online help/FAQ: https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_changing_compiler_version.html https://content.helpme-codesys.com/en/CODESYS%20Development%20System/_cds_cmd_update_device.html See also 4.3.22.4 "How to open an Example Project" within the following pdf for more details on the single steps: https://forge.codesys.com/lib/counit/tickets/_discuss/thread/3e991befbc/ca97/attachment/Public%20FAQ-v13-20240610_075228.pdf Regaring your OPCUA connection state always showing just "DISABLED", without knowing both sides of the assembly in detail, one can only approach the problem theoretically. We can give a chekclist on how to proceed: Fist, please recheck the communication settings in the OPC UA connection function block to ensure that the server URL, endpoint URL, and other settings are correct and match the configuration of the OPC UA server. Verify that the OPC UA server is running and accessible. -You can try to connect to the OPC UA server using a separate client, such as UAExpert, to ensure that the issue is not related to the OPC UA server itself. Test the security settings in the OPC UA connection function block to ensure that the correct security policy and certificate are selected. If you are using a dynamic connection to the OPC UA server, probe that the connection settings are correctly configured and that the OPC UA client is able to establish a connection to the OPC UA server. Also, please loock into the log files for any errors related to the OPC UA connection function block, these should be listet there. The log files may also provide additional information about the issue and help you to further troubleshoot the problem. FYI - Please see https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_obj_data_source_communication_opc_ua_server.html: Her you can finde the Communication settings via OPC UA Server -> layout Browse Live Server: The client connects to the server and detects the existing variables and types. From Information Model The client reads the data structure (layout) of the OPC UA Server from the information model set here and as a result receives the information about available variables and types. A connection to the server is not required. The list contains the information models installed in the OPC UA Information Model Repository. "Read Connection" Settings from IEC Variable (option set): - The connection settings used by the device are not read here from the dialog, but at runtime from the IEC variable specified here. - For this possibility, please see the Using a Dynamic Connection to an OPC UA Server (https://content.helpme-codesys.com/en/CODESYS%20Communication/_comm_use_dynamic_opc_ua_server_comm_settings.html) The settings for the communication of a Client-data source to an OPC UA Server can also be dynamically configured from the IEC code and can also be changed at runtime. For such a purpose, a structure is available in the DatasourceOpcUAServer library (For a description of the OPC UA Server, there is one included in the standard installation of CODESYS, https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_encrypt_communication_data_sources_opc_ua_client.html)
