Post by r-niedermayer on OPC UA subscriber not operational ^{CODESYS Forge talk (Post)}
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)

Post by ggis on Unable to connect to git remotes through Codesys. ^{CODESYS Forge talk (Post)}
When trying to connect to a Github repository in the Git remotes windows of Codesys, the user can be the account username or the account email, while the password is the Github token. (I know this is an old topic, but I lost some time figuring it out from the guides.)

Post by mmpl on Array to String ^{CODESYS Forge talk (Post)}
I would like to create one large JSON string from an array of objects, where each object contains a value. My current approach involves using a for loop and string concatenation, but with 20,000 elements in the array, this method takes almost 7 seconds and negatively affects the PLC scan time. Is there a more efficient way to accomplish this?

Post by dkugler on Converting hex bytes to float ^{CODESYS Forge talk (Post)}
have a look at UNIONs. With a union you are able to write single bytes to the same adress area which belongs to a float variable at the same time. I like to do a lot of convertions belonging to interfaces and fieldbus in this way, f.eg. word / byte swapping etc.

Hi, thanks for the fast response :) Yes I Have a .err file. Sorry I forgot to upload it. It is a binary file though... "Runtime goes in exception before the shutdown ?" I think it goes into exception at the same time as the power is lost...

Hi all, I’m new to codesys and working on some project. Codesy 3.5 V20 patch 3 Every time I try to use refactor codesys hang and not respond. I was trying to use repair function in installer but this is not helping at all. Wonder if anyone experience this behaviour? Sometimes I have Popup saying : Cannot insert ‘CreateTextFile’ bellow ‘<root>’</root>

Post by yannickasselin on Engineering IDE from linux? ^{CODESYS Forge talk (Post)}
I have been running Codesys IDE in VirtualBox on a Linux Mint host for many many years without issues. I use it every day and it works great. I wouldn't mess around with wine. Would probably just be a waste of time. Codesys Go might be the future of PLC programming on Linux! Can't wait to test it.

Just verified the behaviour. Still is the same. It should be attached here. But I also tried the DCF-file with the axis in the lab with the real drive: The MC_Power block never goes out of busy. Had not time to investigate further, though.
