seems to be an accident but there is a workaround in the Configfile: [CmpSocketCanDrv] AsyncSend=1 and will be solved with 4.22.0.0 Release

That’s a classic CODESYS quirk. As soon as you enable AllowFileTransferServices=1, the web server locks down and demands authentication for everything, including WebVisu sessions. Since you're on a Raspberry Pi / Linux, trying to make the built-in CODESYS web server do both secure file handling and unauthenticated kiosk visu is usually a losing battle. A couple of ways to get around this: The cleaner route (separate the jobs): Turn AllowFileTransferServices back off in the config so your kiosk WebVisu...

Title: Cartesian XY Chart — 2-D array binding: "Element to use" enumerates the wrong dimension; documented example (Dialog: XY Chart Configuration, "Two-dimensional array of base type REAL") appears transposed Product / version: CODESYS Development System V3.5 SP21 Patch 40 (3.5.21.40). Cartesian XY Chart visualization element (System_VisuElemXYChart / VisuElemXYChart).

Hello everyone, I have the same problem. I have a Linux-based system with CODESYS 3.6.22.20, and I need to download some files from the external web panel. I have enabled: [CmpWebServerHandlerV3] AllowFileTransferServices=1 In this case, I can see the login page when the web panel connects to the device. I can't disable the device user management access because I need to prevent software modifications. Do you have any ideas? Regards,

these credentials are saved in the plc - you need to ask Festo how to do this.

Hi, I am new to CODESYS, and I want to program a new FESTO, but I am getting this authentication screen. I don't remember the password. I tried with Administrator/Administrator and some other defaults I found online but nothing works. I also tried searching for CODESYSControl_User.cfg and many other recommended directories but I dont seem to have any of them (like CODESYSControlWinV3x64) Could you please help me understand what I need to reset? Thanks a lot
