I'm no longer working with this PLC brand, but if I were you, I would try to stop all related Codesys services before the copy and restart them after that.

Keep in mind that due security reasons the files need to be in the PlcLogic directory! This is since SP19 implemented. https://www.codesys.com/security/security-reports.html see 04.04.2023 CODESYS Control V3 file access

Hello eschwellinger, Many thanks for your test, interesting, mean you can built it without any error? I will delete all the others files and only keep the projet file and see if I still have the errors.

No, you can´t. I have only tried different browsers on my PC and then on my HMI device. Unfortunately the device´s browsers did not support pdf file as I needed so I had to switch to *.txt.

Hi eschwellinger, Thanks for replying, but I'm not shure if I got it right. Do you mean that I have bad configuration on my CODESYS config file? Or in my project? Thanks in advance!

Seems like you use SIZEOF as size, but you need to use LEN as size of data which you want to write.

Post by eschwellinger on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
the project has only one OneWire Master - so if you add the setting "PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ to the config file it will fail and the Ethercat task will be blocked by the OneWire Master readings?

Post by durallymax on Source code changes since last download ^{CODESYS Forge talk (Post)}
What do the details show? Is it requesting an online change or download? If the compile file is missing, it will request a download. Several things can trigger an online change, if you haven't changed the code, likely libraries. The details should provide some guidance.

You actually can use copilot by PLCOpen XML file exporting/importing. It's fine to work with it directly (at least, the Codex do it quite well).

Post by konstantin on Lenze i950 Servo and WAGO PFC200 ^{CODESYS Forge talk (Post)}
Hello, In our workshop we have a Lenze i950 servo drive that has an EtherCAT bus and CiA402 compatibility. The WAGO is PFC200 750-8212 and as per documentation it has built-in license for SoftMotion Light functionality. It is not capable of supporting the full SoftMotion functionality like gearing and synchronizing. I added the EtherCAT esi files from Lenze and the EtherCAT master does see the drive, then I added a SoftMotion Light Axis object. The problem is that I can only energize the axis, I cannot execute any other commands. I set the positive and negative torque limits from the PDOs to 200% and when I try to move the axis by force it does not move back to its original position. I use the SML function blocks from the PLCOpen library and the error from the function blocks is that the op mode cannot be changed. Then I tried using a standard SoftMotion axis object and everything works fine, except the MC_Home function block. The axis moves back to its position when forced out of it. I follow this guide from Lenze - Lenze i950 CODESYS V3 What could cause this issue with the SoftMotion Light axis object? Best Regards Konstantin Kolev

Post by agentcousto on [Bug report] Issue with Importing XML Files Containing "POINTER TO" Variables in Codesys Platform Plugins Versions 2.7 and 2.8 ^{CODESYS Forge talk (Post)}
Hello, I have developed a Python script that I run to import XML files into my project. For this, I use the Python function import_xml(). Everything was working fine when I was using Codesys platform plugins version 2.6.1.2320, but since I upgraded to versions 2.7 and even 2.8, some files are no longer imported correctly. After some research, I identified that all the files containing variables of the type "POINTER TO" are affected. I have attached a screenshot of the error I am encountering. Do you know about this bug? Do you plan to fix it?

Post by spiessli on Objects in OPC UA Information Model ^{CODESYS Forge talk (Post)}
Hi, I have an OPC UA information model with objects defined in it. I can import the model and use the data types defined in it and create instances of these types. These instances are accessible at Root > Objects > DeviceSet > CODE[...] > Resources > Application > GlobalVars > OPC_UA_Symbols for created instances and at [...] > Programs > PLC_PRG for mapped instances. The object defined in the information model is accessible in UA Expert by the name I have defined in the information model (Manipulator) at Root > Objects > Manipulator. How can I assign values to the Variables defined in the object "Manipulator"? Cheers, spiessli

Post by fari on Configure J1939 I/O Mapping via Scripting ^{CODESYS Forge talk (Post)}
Hi everyone, With the latest version of Codesys, it’s now possible to import DBC files directly into the J1939 Manager, which is great. However, I’m trying to achieve the same thing programmatically and can’t find any scripting functions related to import_dbc or any host_parameter that would let me configure PGNs and signal mappings automatically. So far, I’ve managed to add the J1939 Manager and an ECU, and I can pass the DBC database to it, but I’m stuck when it comes to adding the signals. Has anyone figured out if this can be done through scripting? (Attached is an illustration of what I am trying to accomplish programmatically). Thanks in advance.

Post by matthew on Persistence Manager Backup ^{CODESYS Forge talk (Post)}
Hi, Is there a process to restore Persistence Manager files? I have backups of persistence variables used in a machine that is currently operating and tuned and all set points adjusted. There are about 500 persistence variables, they are building another identical machine. I would like to use Persistence Manager files from the first machine in the second also. I have tried copying the files and replacing them on the new RPI but then the Persistence Manager gets errors and then they are all reset to 0 etc I have tried adjusting the times to match. Instead of replacing whole file, I tried just changing the contents inside the file, but still does not work. I may be missing something here, but surely there must be a way to load a backup. Thanks!

Post by micik on Download EtherCAT project on SoftPLC (ControlWin-V3 x64) ^{CODESYS Forge talk (Post)}
Hello, I have almost exactly problem already discussed here in this old thread: https://forge.codesys.com/forge/talk/Engineering/thread/03af9426eb/ However, this is quite old and I assume not completely relevant. In my case, I use v3.5.20 on windows 11, so Winpcap is no longer supported on newer OS. Also, this hint about adding entry to the .cfg file under ProgramFiles(x86) is also not relevant anymore. I guess, I need to add entry SysEthernet to this .cfg file: C:\ProgramData\CODESYS\CODESYSControlWinV3x64...\CODESYSControl.cfg like this one: [ComponentManager] Component.1=CmpTargetVisuStub Component.2=CmpWebServer Component.3=CmpWebServerHandlerV3 Component.4=SysCpuMultiCore Component.5=SysReadWriteLock Component.6=SysCpuBreakpoints Component.7=SysPipeWindows Component.8=SysEthernet But I'm not sure about Npcap vs WinpCap. Please, if applicable, update these instructions.
