"Hello, I'm Cedric Lee, a PLC engineer based in Korea.

I'm reaching out about an ongoing issue with the connection when attempting to control Beckhoff modules using Raspberry Pi with CODESYS for the first time.

I use CODESYS to target the Raspberry Pi's IP, install version 4.10.0.0 of the CODESYS Runtime Package, and upon pressing Start in the Runtime, the target connects to the Raspberry Pi. However, within about a minute, an error window appears, stating 'no connection to the device. please rescan your network,' leading to the disconnection of the target. This cycle repeats.

I've attached some pictures for your reference.

I'm using CODESYS Development System V3, Raspberry Pi 4 Model B (installed as 64-bit), and Beckhoff EK1100 modules.

If anyone has a solution to this issue, please help. Your assistance is greatly appreciated."

Hello,
i have exact the same problem.
could you solve the problem?

greets Tobias

the problem is bookworm, please use the October release, this will be fixed with 4.11.0.0 of the plc runtime release (February)

Sorry Eschwellinger, but the October release is the one that doesn't work...

TY

no October works - but you should not do any update to the October relase
