Post by valenting on Runtime not working on raspberry pi Bullseye ^{CODESYS Forge talk (Post)}
Hello I have a problem with Codesys on Raspberry pi with Bullseye The device is not recognized as a Raspberry pi, as I get this error : ooops... this runtime was built for RASPBERRYPI. Hardware version or firmware version not supported! (-18, 0x00000BB8, 0xFFFFFFFB) I'm running Codesys on a compute module 4S with Raspbian GNU/Linux 11 (bullseye), my kernel version is Linux 5.10.90-v7l+ Codesys version is the latest, released last week (4.11.0.0, CODESYS Control V3.5.19.61 for ARM-32Bit - build Feb 22 2024) I know it works on the same device if I use Raspbian 10 (Buster) with Linux 5.4.81-v7l+ kernel, but for some other reasons I have to use Bullseye. What can I do ?

Post by comingback4u on Memory Address Overlap ^{CODESYS Forge talk (Post)}
Hello, We use a controller that comes with a bunch of predefined faults. These faults are considered active and historic. They are a 32 byte array but only take up 26 bytes of data. Because of this the historic faults start at address 26 instead of 31. Active faults variable take up address location 0 to 31. Historic faults variable take up address location 26 to 57. Because of this overlap I get an error that these overlap and it wont allow me to download to my controller. This isn't an issue in 3.5.5.4 but becomes an issue in newer version. Is there a way to turn this off? If I change the address location, the historic faults then become broken without doing some manipulation in the code. The software will build just fine. Thank you for your time.

I recognized that I have to start the two services "/etc/init.d/codemeter" and "/etc/init.d/codemeter-webadmin" in the docker container as well. If I do so, then the command "cmu -x" returns root@sensoredge-field-netfield-produktmanagment:/# cmu -x cmu - CodeMeter Universal Support Tool. Version 7.60c of 2023-Aug-09 (Build 5625) for Linux/ARMHF 64-Bit Copyright (C) 2007-2023 by WIBU-SYSTEMS AG. All rights reserved. So this time there is no indication any more that "Codemeter is not running". But still we are getting the error when using the license manager in CODESYS development system.

Post by peterned on CNC - system goes to X=0 Y=0 before CNC file execution starts, how to avoid that? ^{CODESYS Forge talk (Post)}
Hi, I have a XY system and use a CNC file to move it. Everything works OK, except for the following: when CNC execution starts, the system rushes at high speed to (X=0, Y=0) point, and only then goes to the first line of the CNC file. If one of the axes is near 0, the system jumps and immediately stops with an error. In the CNC file settings (screenshot attached) I specified low default values for speed/acceleration and a start position different from 0,0 - but all that is ignored. Any idea how to avoid that move to 0,0 ? Thanks.

Post by esave on Softmotion Light Problem: The license is missing or invalid ^{CODESYS Forge talk (Post)}
Hello everybody I want to controll a stepper driver from Leadshine (EM3E-556E). The EtherCat slave is CiA 402 compatible. Because of this I bought the Softmotion Light Package from Codesys and implemented it in my project. I rightclicked the EtherCat slave and added the Softmotion Light axis. But now the error message shows: "The license is missing or invalid. The PLC runs in demo mode." What have i done wrong? I use Codesys 3.5.17. Is it possible that the stepper driver is not compatible with the Softmotion license? Thanks for all your help

Post by fugtwad on Automation Builder V2.5 EtherCAT CM579 Master Scan for devices - >No gateway selected ^{CODESYS Forge talk (Post)}
ABB Automation Builder v2.5.0.22 Premium CodeSys 2.3.9.62 Running on Win 10 VM x64 Goal: I have an EtherCAT topology issue which normally a "Scan for devices.." on the EtherCAT master would shed some light on. Issue: Upon trying such I get a "No gateway selected" error. Question: How might I point the the "scanner" at a gateway? What is working: Gateway is running in system tray. I can go online to PLC. A scan from the "Diagnostics live" tab of the EtherCAT master gives slave status. What I have tried: Restarting gateway in system tray. Exiting system tray gateway and reloading it. Turning off firewall. Contacting ABB support multiple times. Any help appreciated.

Post by kronlundo on Licensing info not available (WAGO PFC200 + Codesys V3) ^{CODESYS Forge talk (Post)}
Hi! We're using a WAGO PFC200 for several projects towards the energy sector, and recently upgraded to CODESYS V3. We have the "IEC 60870-5-104 Server" package in a test program, and it works well with the package in DEMO mode. However, when we acquired a license for the "IEC 60870-5-104 Server" package and tried to add the license on the PFC200 through the license manager, we get an error (see attached file). It seems like there is no CmContainer on the device, does anyone have an idea on how to fix this? We've also contacted WAGO on this issue a while back with no feedback yet.

Good afternoon to everyone; I'm stuck with this error and I don't know how to get out from it... I tried several time googling for alternative systems to control the PLC applications and resets but without success. I would like to realize the possibility to reset the CPU and to start/stop the applications as it was possible with the SysPlcCtrl23, but this library is no longer supported in 64 bit systems and it seems due to the cmperrors interfaces sub library that was included in the above said one. Someone found a work around for this issue?

Post by mborchert on PFC100 Error "Bus not running" ^{CODESYS Forge talk (Post)}
Hello, i currently want to use a wago 750-8102 with the "codesys control for pfc100" runtime. I want to add the devices connected to the internal pfc100 bus via the "search devices" tab. This was reccommended in the following thread: https://forge.codesys.com/forge/talk/Deutsch/thread/7701332199/ But whenever i try to search for devices codesys just doesnt find anything and i cant close the "search devices" window. Has anyone got an idea what the problem might be? I already tried adding the devices connected to the pfc100 manually but the bus just doesn´t start. best regards Moritz

Post by kazuhiro on Problems using MySql Library and SysProcessExecuteCommand2 together ^{CODESYS Forge talk (Post)}
I use fbMsSQL_compact(FUN) of the MySQL Library to write data to the database. There is no problem when writing data using only fbMsSQL_compact(FUN). However, when I try to write data obtained using SysProcessExecuteCommand2 to the database using fbMsSQL_compact(FUN), an error message "Dest server on ip address:xxx.xxx.xxx.xxx and port:1433 is unreachable" appears and writing is not possible. From what I have researched, it seems that writing is not completed in one cycle of fbMsSQL_compact(FUN), and when SysProcessExecuteCommand2 is executed first in the second cycle, the work done in one cycle of fbMsSQL_compact(FUN) is reset. Could you please give me some advice?

Post by ron-rp on Errors with VisuUserManagement library ^{CODESYS Forge talk (Post)}
Hi all, I've played a bit with the VisuUserManagement library, and some other security option in my project, and I started getting this error when logging in - see attached pic. something to do with a specific screen in the library - VUM_Login. Also, Codesys started to ask me to log in to the library when logging in, asking to log in as user of the groups Maintainer or Owner, which I dont know either users (attached pic). when I close the login screen and try to log in to the PLC again, everything works again until I close and open Codesys. I do use user and password to login to the PLC, and this login screen is fine I know the user and pass I setup. anyone know what did I do wrong here and how to fix it?

Post by sheberle on No Bootproject possible ^{CODESYS Forge talk (Post)}
Hello Alex, the message is generated by the CODESYS code generator based on the DevDesc settings of the memory areas available for the target. The problem arises when after too many online changes the area is full. Therefore no more boot project can be generated. Short-term remedy as described in the dialog: Clean and fresh download. This way the initial memory size will be "used" again After how many online changes did this error occur? There is no set limit on the number of online changes, but making too many changes could be a risk. br Simon

The licence has been activated with a computer Name, but the guy who did it make a mistake in the name, so he changed it after to have activate the licence. I think this has created a second container. The licence is actived on the other container.

Post by gseidel on CAM Motion Recover after STO ^{CODESYS Forge talk (Post)}
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, with absolute master position and absolute slave position. Choose the StartMode that is appropriate for your machine. Best regards, Georg Seidel

Post by poliautomacao on Absolute movement controlled by an external encoder. ^{CODESYS Forge talk (Post)}
Hello, I made this configuration, I'm moving the encoder value to SM_Driver_PosControl.in.wActPosition. When I make the absolute movement of my PosControl axis, my physical drive axis rotates perfectly, but I noticed that the movement is not followed by the encoder. That is, if I hold the encoder and keep it in position 0, the PosControl axis makes the absolute movement of 314 mm and stops, which is strange because the encoder is at 0. Theoretically, the PosControl axis should accelerate to try to compensate for the movement error. I haven't yet achieved perfect functionality.

Post by egr99 on Modbus TCP Server connection is ESTABLISHED but all holding registers are value 0? ^{CODESYS Forge talk (Post)}
You're absolutely right. Sorry for that. In the meantime I wrote a Function block to handle the reads and writes to the different attached RTU-devices. It processes the parameter like (str_Modbus:=(usiSlave:=1, uiFC:=5, uiLEN:=1, uiOFFSET:=0, uiInterval:=500)) and the corresponding output, waits for the response and processes next request in a 5-state procedure. It's working for 2 gateways (stable without errors, although error recovery is included). But nevertheless it should be possible with the Channel definitions of Codesys. Much easier to maintain :)

Post by vstrom on Codesys v3.5.22.10 - Fail to create a project Archive ^{CODESYS Forge talk (Post)}
Hi to all, I've created a project using the File->New Project-> Standard Project command. Then I've add the object "Visualization Manager" and then tried to create a project archive (File->Project Archive->Save Archive), but it fails with the error "Access to the path 'C:\Program Files\CODESYS 3.5.22.10\CODESYS\Common\3hxi4iod.put' is denied". The idicated file don't exist. First time of use of the new Codesys versionù, I've reinstalled the developement software but nothing change. If I don't add the Visualization part, the archive is created, it's seems to be a problem with the HMI part. Any ideas? Thanks

Post by jorenbeyl on library inside library ^{CODESYS Forge talk (Post)}
I am currently developing a library that contains real‑time data. To handle this real‑time data, I am using additional libraries called SysTime and SysTypes Interfaces. When I compile my library on its own, no errors occur. However, when I use this library in a project and compile the project, I get an error indicating that the SysTime data type is not recognized. This happens even though the SysTime library is visible as a dependency under my library. Does anyone know how to correctly include a library within another library so that the project recognizes the sub‑library without causing compilation errors?

I have the following setup: Proxmox PC with a debian 13 VM running CODESYS Control Linux SL and Edge Gateway. Installation method was through the Deploy Control SL and went rather smoothly. In my Device Tab I find the gateway and when scanning my network I also find my runtime. I want to connect and get promted that I should add a user. After setting up the user I get an error saying, that the device is not responding my scanrequest. Deploy Control SL Operation saying everythings up and running. I can confirm that from the terminal on the VM with "systemctl status codesyscontrol" and "systemctl status codesysgateway". I am running out of ideas how to fix that issue. Can anybody help? Screenshots attached.
