Post by alexgooi on Disable OPC-UA server ^{CODESYS Forge talk (Post)}
Dear Forum, I recently updated to the newest Codesys IDE (3.5 SP19 patch 5) The program wouldn't download cause of the amount of OPC-UA server tags (see picture) I'm not planning on using the OPC-UA server and therefore I unchecked the "Support OPC-UA features" checkbox in the symbol configuration. But this didn’t solve the issue of the OPC-UA server exceeding its license. How can I disable the OPC-UA server while still maintaining the symbol configuration. Thank you in advance Alex

Post by alexgooi on OPC-UA Boolean format ^{CODESYS Forge talk (Post)}
Dear Forum, We are currently making the switch from OPC-DA (Codesys server) to OPC-UA (Running on a Codesys controller). We are using Codesys version 3.5 SP 20. Our Scada system is expecting Boolean's to be represented as a 0/1 (True Boolean) but the OPC-UA server is representing a boolean as False/True This indeed matches the OPC-UA standard, but is there a way to configure the OPC-UA server's boolean representation? Thank you in advance

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)
