Post by bschraud on runtime received SIGABRT ^{CODESYS Forge talk (Post)}
Hallo, seit der Umstellung meines Projektes auf die aktuelle Codesys Version mit aktuellen Bibliotheken und Aktualisierung der Runtimer Version bekomme ich im Zeitraum 15min bis 1h nach Neustart des Target Systems folgende Fehlermeldung: runtime received SIGABRT - system may be in an inconsistent state Der Fehler kommt auch nach dem Start des Systems ohne eine Benutzeraktion zuverlässig, aber in unterschiedlichen Zeiträumern. Hier sind die Logs und Daten, die ich dazu ermitteln konnte: $ tail -f /var/opt/codesys/codesyscontrol.log 2025-04-03T06:54:37.659Z, 0x0000100c, 1, 0, 0, Visu_PRG: Creating Client for Extern-ID: 594337835 2025-04-03T06:54:37.660Z, 0x0000100c, 1, 0, 0, Visu_PRG: Creating Client successful for Extern-ID: 594337835 Returned IEC-ID: 0 2025-04-03T07:01:38.135Z, 0x00000103, 65544, 1, 0, runtime received SIGABRT - system may be in an inconsistent state * We recommend a reboot of the controller now! 2025-04-03T07:01:38.135Z, 0x00000111, 8, 260, 3, #### Exception: HANDLED EXCPT* <excpt>NonContinuable</excpt> in CH_COMM_CYCLE 2025-04-03T07:02:18.181Z, 0x00000103, 65544, 1, 0, runtime received SIGABRT - system may be in an inconsistent state * We recommend a reboot of the controller now! 2025-04-03T07:02:18.181Z, 0x00000111, 8, 260, 3, #### Exception: HANDLED EXCPT* <excpt>NonContinuable</excpt> in CH_COMM_CYCLE $ vmstat 1 procs -----------memory---------- ---swap-- -----io---- -system-- ------cpu----- r b swpd free buff cache si so bi bo in cs us sy id wa st 1 0 0 271120 33976 342284 0 0 135 2 2387 4751 10 7 82 1 0 1 0 0 271024 33976 342380 0 0 0 0 10163 20427 10 9 81 0 0 1 0 0 271056 33976 342380 0 0 0 0 8455 16869 9 5 86 0 0 0 0 0 271040 33976 342380 0 0 0 0 8674 17484 9 4 87 0 0 0 0 0 271072 33976 342380 0 0 0 0 10070 20350 7 7 87 0 0 1 0 0 271040 33976 342380 0 0 0 0 10354 20802 10 6 84 0 0 0 0 0 271072 33976 342380 0 0 0 0 8401 16923 8 6 86 0 0 $ vcgencmd measure_temp temp=56.9'C $ uname -a Linux PAC4 5.10.103-v7+ #1529 SMP Tue Mar 8 12:21:37 GMT 2022 armv7l GNU/Linux CODESYS V3.5 SP21 Runtime: Codesys control for Raspberry Pi MC SL V 4.13.0.0 Hinweise auf ein instabiles OS oder instabile Netzwerkverbindungen konnte ich keine finden.

ja danke hilft definitv & sorry- das wird verbessert, künftig werden die Packages & Beispiele nach "c:\Program Files\CODESYS <version>\CODESYS\CODESYS Control for Raspberry PI\<version>\Examples\" installiert werden.</version></version> Beispiel für die PI Beispiele: "c:\Program Files\CODESYS 3.5.19.30\CODESYS\CODESYS Control for Raspberry PI\4.10.0.0\Examples\" dass wird für alle Aktualisierungen/Updates der Packages so ausgerollt.

Also had this problem when working on legacy project. My packege was CODESYS Code Generator ARM 4.0.3.0.package. To manage this I used PackageManagerCLI.exe. This tool does not validate certificates appearently. My command: "C:\Program Files\CODESYS 3.5.17.30\CODESYS\Common\PackageManagerCLI.exe" --profile="CODESYS V3.5 SP17 Patch 3" --install=""C:\Users\sample_user\AppData\Local\Temp\APInstaller\5wx1k02a.r2t\CODESYS Code Generator ARM 4.0.3.0.package""

I will use Codesys to program a PLC. I will connect the PLC to the computer via the CAN interface using PEAK CAN, but Codesys does not recognize the CAN adapter. I have added the following libraries. What should I do? What steps should I follow?

I also had this problem connected CODESYS to UAExpert for the first time. In the device, I need to allow anonyomous log in. Follow steps 14 - 17 of the following tutorial: https://docs.factoryio.com/tutorials/codesys/setting-up/codesys-opc-ua-sp17/#creating-the-project

Open the CODESYS Installer (from the menu Tools). Go to Browse. Search for: help ... Select the CODESYS Offline Help which you would like to install. (probably you have to close CODESYS to install it and reopen it after installation).
