Cloud Connectivity Issue On 750-8208

CODESYS
1

I’m currently working on establishing a cloud connection using a WAGO PLC 750-8208. I followed an example program shared in the WAGO Community, but I’m encountering issues related to firmware versions during implementation. The problems I’m facing are as follows:

  • Firmware Version 17:
    The cloud connectivity code downloads successfully into the PLC, but the PLC does not switch to RUN mode after the download. It remains in STOP or error state.
  • Firmware Version 22 (Latest):
    After upgrading the PLC firmware to version 22, attempting to download the same project results in an FB block error, preventing successful deployment.

I suspect these issues might be related to firmware compatibility, library mismatches, or additional configuration required for cloud connectivity. I would appreciate any support or suggestions from the community to resolve these issues for both firmware versions.

Hello,
The problem is probably in the PLC Configuration which block the program to go in RUN mode.
Open the PLC Configuration page,
In the Extra menu, click on Standard Configuration.
Click on Yes to roll the configuration to a standard one for the 750-8208.

Reboot the PLC with the Run switch on STOP.
In codesys Go online to upload the latest program.
Use the Run switch to change the program state to RUN.
