Hello,
I am testing the PLCnext Controller AXC F 3152.
We want to create our own software and run it on the controller. To this end, I am testing the C/C++ examples shown in the “getting-started” section of GitHub - PLCnext/SampleRuntime: Integration example for other runtime systems using the PLCnext ANSI C interface · GitHub.
After several days of troubleshooting, I have identified a reproducible issue:
As soon as I install a program that uses the PLCnext API, it is no longer possible to restart the plcnext service.
After the initial installation or a power cycle, the “Runtime” program starts and writes the board temperature to the log.
After running
sudo systemctl stop plcnext
the service does not shut down cleanly.
Here is a log excerpt:

Jul 06 11:35:40 axcf3152 systemd[1]: Stopped PLCnext Application.
Running sudo systemctl start plcnext naturally doesn’t work. A reboot or power cycle is necessary.
My setup:
- PLCNext Engineer 2026.3
- Controller in the project is set to 00/2026.0.0
- Controller AXC F 3152 HW 03, no modules installed
- Firmware Controller 2026_0_4_LTS
- Toolchain PLCnext_Toolchain_Linux_2026.0-LTS
- sdk axcf3152_linux_sdk-2026.0.1_LTS-26.0.1.68
- target in the project is set to AXCF3152,26.0.1.68
A reliable restart of the plcnext service is essential for the productive use of the AXC F 3152 controller.
Can anyone help?
Has anyone successfully got C/C++ programs running on the 3152 controller?
Many thanks.
