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.

Post by eozupek on File Transfer Error 4 ^{CODESYS Forge talk (Post)}
I couldn't exactly solve the file transfer when I wanted to do multiple transfers while the compiler was open in a way that I couldn't understand. Notification from target: runtime received SIGABRT - system may be in an inconsistent state * We recommend a reboot of the controller now! * details of the target component that sent this notification: [CmpName=SysExcept, CmpId=0x00000103, ClassID=0X0001008, ErrorID=0X00000001, InfoID= 0X0000000j] I see the warning. I couldn't find out why error code 4 is coming or what kind of measures I need to take to prevent it from coming within the application. Can you help me? regards Emre OZUPEK

Post by i-campbell on What does CODESYS expect to do when I get such an error message ^{CODESYS Forge talk (Post)}
you need to get the addons that the person that programmed it used. I always store an .installation-config file alongside the project. If you have lost that, then it gets a bit of a headache: I think even with SP18 you can hit yes to open it anyway, and it will suggest which addons it thinks are missing, if you double click the yellow "missing-addons" in the status bar. If you know you have the right addons, you can do a "Save As.." and it will write your current addon list to the file, and you wont get the error next time.

Post by alexgooi on Is it possible in the log to see previous shutdown ^{CODESYS Forge talk (Post)}
Hi DavidBo, In general Codesys is used to control equipment and an exception is the worst thing that can happen in your installation. If you cannot prevent the exception from triggering, you could implement a Try catch statement, with this solution your controller keeps on running and you are able to handle the exception. __TRY //This statement will trigger an exception Result := 4/0; __CATCH(exc) //Handle the exception HandleException(exc, strExceptionText => strExceptionText); // From the Codesys help file //Create a log file //-------------------------------------------------------- __ENDTRY What you also could do is implement implicit checks, these functions cover most of the exceptions (like dividing by zero) See picture But in general avoid a complete controller shutdown!

Post by s1mon on Two OneWireMaster on one Raspberry PI 5 ^{CODESYS Forge talk (Post)}
I don't know why the EtherCat fails, but what happens is: First I have only one 1WireMaster running on my Raspberry Pi and EtherCat is running fine. Then I'd like to add a 2nd 1WireMaster. Therefore I enable a 2nd GPIO Pin on the raspberry in the file "/boot/firmware/config.txt". dtoverlay=w1-gpio,gpiopin=4,pullup=0 dtoverlay=w1-gpio,gpiopin=23,pullup=0 To be able to use this 2nd 1WireMaster in Codesys Runtime I Adjust the CODESYScontrol.cfg file and add there: PlaceholderFilePath.2=/sys/devices/w1_bus_master2, $OneWire2$ After a reboot the EtherCat Master is not working any more. I didn't even add a 2nd OneWire Master in Codesys, but still if I do the EtherCat does not work. Do you have an idea why?

Post by timvh on Codesys complains about matching versions ^{CODESYS Forge talk (Post)}
Open the CODESYS Installer. Create an export file from your current PC from your current version. Then on the other PC Open the installer and install a new version based on the same essentials version, but additionally select the export file which you have created on the first PC. Or just install (import) it within the already existing version. For the installer, you can install it from: https://store.codesys.com/en/codesys-installer.html For help see: https://content.helpme-codesys.com/en/CODESYS%20Installer/_inst_install_setups_and_addons.html On PC 1, save the project as projectarchive (which will then include all the libraries and devices). Then extract this projectarchive on PC 2.

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.

Post by timvh on Reading multiple lines from csv file ^{CODESYS Forge talk (Post)}
Not sure, but maybe before you enter step 5, set i, lineindex and charIndex to 0. And the buffer variable should have a size bigger than 1 line. Additionally I think you should set bufferstart to 0 before you enter step 5. And in the OSCAT function you always point to the buffer address, but shouldn't this be (buffer + bufferstart)?
