Hello, team!
Faced withe the next situation, while configuration of plc with fw 2026.02 LTS (Project created with ide 2026.3)
If I deactivate Network limiter system service via WBM, plc fail to start project with error “Plc failed: ‘Exception occurred: PLC application not stopped’ - at component Arp.Plc.Eclr on SetupPlc(isChanging=false, startKind=Warm)”

Does it bug or feature?

I can’t reproduce that here.

  • AXC F 2152 FW 2026.0.2 LTS
  • Type 1 reset
  • In WBM: System → Device Maintenance: PLC state = “Running”.
  • System → System services: Deactivate the Net Load Limiter service.
  • Save Page & Restart

=> Connection is lost to the device while it restarts. When the device restarts:

  • Log in to WBM.
  • Diagnostics → Notifications: There are no errors.

What steps have I missed?

Hello!

Do you load to plc some dummy project?

Update on reproducing the issue. It looks like the error is specifically related to the inclusion of the PLCnext_Base 1.8 library.

Here are the exact steps to reproduce:

  1. Update the controller firmware to 2026.0.2. Type 1 Reset after all.

  2. Download a project that includes the PLCnext_Base 1.8 library.

  3. Initialize the library using the PBCL_Setup_1 function block.

  4. Disable the NetloadLimiter via WBM (Web-Based Management).

  5. Reboot the controller. After the reboot, the project fails to start.

Ichtios wasn’t able to reproduce this error on their end, but I am consistently facing this issue and haven’t been able to find a workaround to get rid of it.

Has anyone else encountered this specific behavior?

Ok, since PLCNextBase 1.8.2 this issue seems to be fixed.
