Hello everyone, I am currently using OPC UA in CODESYS with the security mode BASIC256SHA256 – Signed and Encrypted. The OPC UA Server is running on an RTE CX device, and the HMI is running on another computer. I have reviewed many CODESYS documents and successfully established communication when the security mode is set to None with Anonymous login. However, when security is enabled, the server does not provide its certificate for the CODESYS HMI client to trust. Interestingly, the client can send its certificate to the server, and UAExpert works normally, but the CODESYS HMI client does not receive the server certificate. Can anyone help clarify what I might be missing? I have been stuck on this issue for three days. If I missed or misconfigured any step, please let me know. I believe I am stuck at step 15 in the following CODESYS guide: Encrypting the Communication of a Data Source OPC UA Client https://content.helpme-codesys.com/en/CODESYS%20Communication/_cds_encrypt_communication_data_sources_opc_ua_client.html Thank you very much.

Hi bertus, the coordinate systems used in SoftMotion CNC are all right-handed. The CNC editor uses isometric projection. This can be confusing, as in your example. The y-axis seems to point into the screen, away from the viewer. However, this is just an optical effect. If you turn on the (experimental) perspective projection (must be added to the CNC tool bar using tools->customize), you can see that the coordinate system is in fact right-handed. Best regards, Georg

Hi aniket-b, the maximum cycle time of the EtherCAT_Task is very high, ca. 35 ms. Could you please check if this is just the first cycle after starting the application or if it happens during motion? (You can reset the times in the task configuration by right-clicking in the "monitoring" tab.) Another thing to try: put the SoftMotion_Planning task on a different core. Best regards, Georg

Hello Everybody, Hope you're all doing good for this new year. Since a time, I'm looking on how to use the KeyPad in vizualization to fill a textlist or something similar. my application is : In one window, I would need to be able to writte a string linked to an Numeric Values. => I can't use a std text list inside my software, as per this would be custom by customer. then from another windows I would need a "text box" to be able to select any of this String. I hope it's clear enought. thankyou for the help

Create an array of STRING and 1 INT variable, e.g.: asMyString : ARRAY[0..9] OF STRING; iIndex : INT; Then place a "Table" object in the visualization: - link this to the string array variable. - Check the option "Use Template" - Then in the Input Configuration - add the "Write Variable" command Somewhere else add a "Combobox, array" - link this to the same array. - And link the index to the INT variable. In the Combobox, you can then select one of the strings from the array. The index variable will indicate which selection has been made.

Looking for a game that's both entertaining and a gentle brain-teasing challenge? Welcome to block blast – where classic block-stacking meets colorful modern gameplay! Why is Block Blast so addictive? Simple yet never boring! Your task is to drag and drop blocks of various shapes onto an 8x8 grid. When you fill a horizontal or vertical row, "BOOM!" – they explode, disappear, and earn you points. The fun sound effects and smooth animations make each point-scoring moment incredibly satisfying. Big advantages: No time pressure: Forget the countdown timer. You can think all day about your next move. Play at your own pace! IQ training: Don't let the bright appearance fool you, this game requires strategy. You have to calculate the space to avoid getting "stuck" when difficult blocks appear. Play anytime, anywhere: No Wifi? No problem. Block Blast handles even offline mode. Don't just focus on clearing one row at a time. Accumulate blocks and clear multiple rows at once (Combo) to skyrocket your score. And remember: Don't leave small empty spaces alone; they will be "enemies" blocking the large blocks later!
