Post by milosfejgl on Codesys Licenses - How to reload them after updating the Raspberry Pi OS ^{CODESYS Forge talk (Post)}
We use several control units running on Raspberry Pi, programmed using Codesys software, with multiple licenses stored as soft containers. We are planning to update the SD card image of the Raspberry Pi to a newer OS version. However, we are concerned that this process might result in the loss of our soft container licenses. Is there a way to temporarily deactivate the license so that it can be reactivated on the updated system? Alternatively, what would be the best method to preserve the licenses during the update? Thank you in advance for any responses!

Post by rossanoparis on Internal Error (ARM): Unsupported conversion! With new version v3.5 SP21 ^{CODESYS Forge talk (Post)}
I have updated CODESYS development tool to the version v3.5 SP21 (64bit) The previous version was v3.5.20.40 Compiling an existing application with the new evelopment tool I get the following error. kunbusiodrvrevpibridge, 1.4.1.0 (kunbus gmbh): IoDrvScanModules [IoDrvRevPiBridge](Line 51, Column 1 (Impl)): Internal Error (ARM): Unsupported conversion! This error was not reported in the previous compiler version and is now highlighted in a third-party library, which I cannot change or modify. The error is due to the following conversion: m_udiError := TO_UDINT(excCode); . The excCode variable is a system type, declared as shown below, and should be converted to a UDINT excCode : __SYSTEM.ExceptionCode; m_udiError: UDINT; . I would appreciate it if someone could provide feedback on this issue.

Post by rockallsue on Frustration-Fueled Feedback on Project File Management and Git Integration ^{CODESYS Forge talk (Post)}
Some developers export ST code manually and edit it in VSCode, then copy it back. However, a more practical approach might be using automation scripts (PowerShell, Python) to extract and inject code into the CODESYS project. You could also check if CODESYS Automation Server or CODESYS API allows better ST access for external tools. https://www.codesys.com/the-system/releases-updates-lifecycle/release-plan-roadmap.html Network drive issues are particularly painful. As a mitigation, you could try using local project storage with periodic cloud sync instead of directly saving to a network drive. Using Rsync or Syncthing for automatic but safe synchronization might reduce risks of file corruption.

Post by vformanek on No source code available for profinet library ^{CODESYS Forge talk (Post)}
I have tried downgrading and it seems fine now. I am now on version 4.3.0.0 for the library. Mainly the PN controller caused the issue for me. Funny weird is that even the PN controller versions 4.3.1.0 and 4.3.0.0 cause the error. Version 4.2.0.0 works fine.

looks like you are running in a bug in the newest version 4.4.0 of the profinet library or the new library triggers a bug in your code. did you update your profinet device too? you could try to downgrade to an older version of the library. via library manager - placeholders, double click Profinet 4.4.0 in the library column and choose an older version.

Hi, I have a Beckhoff EL6751 EtherCAT / CANopen gateway which fails on the Canbus when the CANopen_Manager is added. Currently no devices are connected to the EL6751. If I add a device, I get the same issue. If I add a device and connect the bus, I get the same issue. Is there something I am doing wrong? Regards Trevor

Post by laruso on Runtime device Enable/Disable procedure ^{CODESYS Forge talk (Post)}
I implemented the parts from the CAA Device Diagnosis Example.project and could use it for switching on and off, the CAN devices that were located under the CANbus and CANopen_Manager. But i can't do the same with I2C_master_test_version or devices below this one. In the example project there is only the EtherCAT Master, CANbus and CANopen_Manager, and Ethernet with devices below.

Post by totorovic on CSVReaderInit returns error : INVALID_HANDLE ^{CODESYS Forge talk (Post)}
We changed the path where the CSV file is. From intern memory of the IPC to a USB key. We still have this error 'INVALID_HANDLE'. We must restart the Codesys runtime to clear it. That is a big problem for us because machine is in production. @eschwellinger What do you mean by "this is a security issue not to read/write in the plc allowed path"

Post by andrax on Mux I2C ^{CODESYS Forge talk (Post)}
Hi, sorry I was not there for a long time. The TCA9548 needs terminating resistors, do you have them in? That's why I went to QWIIC, the muxboard already has them built in. If it still does not work, try it first without the muxboard. PS: Note the channel assignment. Muxboard 0 = I2C_Master 1,0,0,0,0,0,0,0 Muxboard 1 = I2C_Master 2,0,0,0,0,0,0,0 etc.

Post by timvh on Send file from codesys to...... ftp, cloud, etc ^{CODESYS Forge talk (Post)}
You can use the (open source) FTP client in Forge. This works on 64 bit systems. See: https://forge.codesys.com/prj/ftp-client/code/HEAD/tree/ As this is open, the idea is that when you use it and make improvements to the source code, that you also commit this in a branch so others can also benefit from it.

Hi Sir Kevin. May I know how you came up with this solution. Im a bit confused but I tried to put this. [SysCom] Linux.Devicefile=/dev/ttyRS48 (remember, no 5 at the end!) then set com port in codesys to 6. It also works for me but want to know where did you get this. Thank you.

Post by dhumphries on Execution Order of Function Blocks ^{CODESYS Forge talk (Post)}
Function blocks in a SFC are executed left to right, top to bottom, instructions in ST are executed from left to right top to bottom as well. I think you are asking about the execution of POUs although you use the name function block, I believe POUs are executed in the order they are shown under the main task.
