Dear PLCnext-Team,
I’m testing out the Starterkit 1188165 and have a Local bus error. Like in this discussion (https://www.plcnext-community.net/forum/#/discussion/1632/failed-to-list-local-bus-modules-on-webpage-when-running-starterkit-example), software installation, firmware update, connection with 2152 controller — everything is okay. But I have no interaction between controller and I/O modules. After that I found on WBM the local bus error.
I tried to isolate the problem and removed all modules with exception of AXL SE DO16/1 Rev. >=00/1.00. This module is placed in the first slot of the Module carrier AXL F BP SE4 (left above). In PLCnext Engineer I left also only the AXL SE DO16/1 Rev. >=00/1.00 in „Axioline F“.
But even this one modul isn’t been detected. Diagnostic Registers are:

  • Diagnostic Status Register 0x0084
  • Diagnostic Parameter Register 1 0x0c02
  • Diagnostic Parameter Register 2 0x0002
    Can you please help me find the source of the problem?
    Best regards
    Ivan

The problem is solved.
What I did bevor: I added the I/O modules manually.
How you should do it: right click on Axioline → Read Axioline devices.
It doesn’t matter, that I added the same modules, I had the local bus error. But when the I/O modules are added automatically, it works fine

I am getting Local Bus Error when I am trying to flash code on AXC F 2152 module, and in Axioline, all I/O modules are automatically detected, with correct configuration, I used the software version of 2025.0 and even tried with 2025.2. Firmware is also correct as it shows tick mark when board is detected. I tried flashing the code of basic ladder logic to light LED at Digital output pin 2, as soon as I flash, it gives local bus error and code does not work, I have tried many times but encountering the same error, connections are correct for providing power and connecting other Axioline I/O modules please help me…
I got same error as described above I even tried manually adding the components in Axioline but that also did not work. I am very stressed.
