Post by patrik on Application failing to boot after system reboot ^{CODESYS Forge talk (Post)}
Hi! I'm having issues with my applications failing to boot up after the hardware getting restarted by the customer. I've attached a picture of the related log lines in the PLC log. I'm running this on a windows server. The version I'm currently running is CoDeSys win V3 x64 3.5.19.50 Is there any way to get more information why it's failing to boot? I've had this issue on several versions of the runtime. I don't think it's version related but I don't know. All I know is that sometimes when the client gets a power outage or something that kills the machine some of my applications fail to boot. Any help is deeply appreciated. Thanks in advance!

Post by ac-spr on Runtime variable that indicates a user is online to the code ^{CODESYS Forge talk (Post)}
Looking to access a variable at runtime that indicates a user is online to the code. essentially want to use this value to feedback to the user on the HMI. we use turck and bosch rexroth devices if this information helps. I was hoping there was a variable at the application level, or a library that could be used but I was unable to find anything. I know there's a pop up when you try to login/ go online to the code when a user is already logged in, so the system does provide an indication that it knows already online, but has no access to a value from what I can see. Any help is appreciated

Post by simotion on Codesys Softmotion Win V3 x64 ^{CODESYS Forge talk (Post)}
I have a project in Codesys v3.5 sp19 patch2 that contains softmotion virtual axes. I want to simulation the code (softmotion) on the simulated plc on the pc. The controller in the project is a Codesys Softmotion Win V3 x64. I have started up the Codesys Softmotion Win 64 on the pc. However it seems a 3.5 sp14 controller. When trying to download the project, I get a message that target system is different from connected system (3.5.19 vs 3.5.14). How do I set the connected system to 3.5.20 (there seems no way to set the target system to 3.5.14

Have you tried using the persistence manager which uses the file system of the controller to store persistent variables?

Post by davidbo on RPI can system operation like rm in a shell have an impact on a Task cycle time ^{CODESYS Forge talk (Post)}
I have noticed that a rm file1.txt command on a shell has an impact on the cycle time for a TASK writing to file2.txt. Seen in the Monitor fane of the Task configuration Furthermore if a TASK makes a system call like rm, its cycle time increases of course but it seems to have an invisible impact on other TASKs too. I have a TASK for handling communication over the CANbus (SPI) where it stops sending "Heartbeats" for many seconds when another TASK does a system rm. Why is that not seen on the Monitor fane? Is even codesyscontrol paused when system calls are made? The CPU load is about 30-40%

Which version exactly do you use?

I would check with the CODESYS file browser if these files exits on your system (PlcLogic directory)

*** The system may be in an inconsistent state, please reboot *** *Exception* Async service: ServiceGroup=17, IP=0x5fa45617, Component=CmpSrv Every time at the instant that I Login to the system a message that the "system may be in an inconsistent state, please reboot" is written in the log. If I logout and repeat login a new entry is set. My system is a "Control for linux SL" running on a debian linux host. Im running it on my desk without any IO attached so message might be caused from that, but I doubt i have seen it before. Rebooting makes no difference. Anyone that have a clue of how I should interpret this error message?

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.

Thank you wollview, it is clear now, it is due to security reasons that access to the file system is restricted.

Post by struccc on Application failing to boot after system reboot ^{CODESYS Forge talk (Post)}
I started to experience the same issue, after upgrading to 3.5.19 , and still persists with 3.5.20.3 , using CodesysControlWinV3 x64 on Windows. Unfortunately, this is a live application, normally it is running for months without interruption - so it was a surprise at the last cold start... It was not possible to go online with the original version, so I couldn't see the application, or system status, just the log message. First time I manually clean the Application from the PlcLogic directory (there was no coredump file in there), then I could start the runtime service, and do a fresh download, and set the bootproject. I could not try a cold system reboot - it's in a 24/7 production environment, and I was under heavy pressure to start... What I did, I have created a backup from the * complete * runtime directory, from the failed, and fixed version - before and after download. This directory in my case C:\ProgramData\CODESYS\CODESYSControlWinV3x64\55096128 - At the next shutdown, it was sufficient to copy back this backup completely, and could start the runtime service afterwards. Ugly, but local staff with some skills can do it without programming tool... I don't store any live data, configuration, log files, persistent data in this directory - the only reason I need this is to edit the CodesysControl... .cfg file.... And to see the logfiles in emergencies like this. The application concerned doesn't use any retain area. - exactly for these reasons - Maybe that is causing the problem with the newer runtime versions As far as I see, this problem occurs only if the power of the Windows PLC is interrupted without a proper shutdown. Unfortunately, this can happen sometimes. The newer versions, seems tp modify CodesysControl.cfg on the fly, and register the applications, and bootproject information after download. (I don't really see CodesysControl.cfg a proper location for this... but that's just my feeling) So now I had a look at CodesysCotrol.cfg on my laptop and I found: [CmpRetain] ;Retain.SRAM.Size=0x200200 ;Retain.SRAM.Address=0xFA3C5776 ;SimulateSRAM=1 [CmpApp] ;Bootproject.CreateOnDownload=0 ;Bootproject.StoreOnlyOnDownload=0 ;Bootproject.InvalidateByRename=1 ;Bootproject.InvalidateBySetting=1 ;Bootproject.InvalidateNever=0 ;PersistentForce=0 ;RetainType.Applications=InSRAM ;RetainType.Applications=OnPowerfail ;RetainType.Applications=None ;Exception.Hardware.GlobalStop=1 Application.1=MyTestAppNoRetain The last line appeared after download and boot project creation. Maybe... Should set RetainType.Applications=None? I wonder about all these settings, but... Will write separately about it. I hope this helps a little...
