    hi, When I try to establish communication between CODESYS and Fuxa SCADA via OPC UA, the connection fails, and I receive the following error: 2026-02-15T08:38:13.618Z [ERR] 'codesys' connect failure! Error: The connection may have been rejected by server, Err = (ClientTCP_transport6: socket has been disconnected by third party) 2026-02-15T08:38:13.619Z [ERR] 'codesys' try to connect error!

    Hello, First post here. I would like to clarify whether the following behavior is known or if it is a bugs. Issue 1 — First row not displayed when using Maximum array index with 1-based arrays Description: When displaying data from an array that is indexed starting from 1 (e.g., ARRAY[1..N]), and the number of displayed rows is limited using the Maximum array index property, the first row of the array is not shown in the visualization. Steps to reproduce: Create an array indexed from 1 (e.g., ARRAY[1..N])....

    Dear Mr. Kolev, I'm not sure I understood correctly. But this is my take on your question: When the STO of the slave is triggered, store the current master position (e.g. 225 units) After the reset of the slave error, call MC_SetPosition on the virtual master and reset it to the stored position (225 units) Optionally, before MC_CamIn is restartet, move the slave back to the slave position corresponding to the stored master position. (If you do this, no ramping in will be necessary) Restart MC_CamIn,...

    Downloaded and installed edge gateway 4.19.0.0. Unfortunately same behavior: "Control for Linux SL" NOT shown in drop lists on either "Deployment" Tab of tool "Deploy Control SL", or as "installed packages" on "Operation" tab (only "CODESYS Edge Gateway for linux" is shown).

    guess you'll need to use latest CODESYS version to fix this.

  • fajean posted a comment on discussion Engineering 🇬🇧

    We make heavy use of internally developed libraries, which are often nested on multiple levels. I routinely work simultaneously on several libraries along with a project that use them. I make changes to a library and immediately perform a download (online or otherwise) in the project. For the longest time, we had zero issue with this. But starting a good while back, with 3.5 SP19 I think, CODESYS started not noticing library updates in other instances most of the time. When the update is missed,...

    I don't have time to go through the whole manual but as I said earlier, the servo drive does not support any of the modes needed for SoftMotion Light to work. If you want to use the full SoftMotion, you could use SMC_Homing function block to do the homing. This function block does not use the Homing Mode. It still uses the CSP mode and does the logic in Codesys runtime instead of in the servo drive. Read the documentation about it to see if it fits your needs. But if your controller only supports...

    Hello, basically the i950 drive support CiA402 Basic and CiA402 Advanced modes. I attached pictures of both mode supported functions. It also support CSP, VL, CSV and CST modes. It seems the homing mode is in CiA402 Advanced mode but how can you not have the homing mode in both modes? It is a vital part of any servo system. If I use the SoftMotion standard demo mode, I can move the servo absolute and relative but cannot home it. But in SoftMotion Light mode, I cannot execute any motion function....
