Hello everyone,
I’m using CODESYS on my RevPi Core S and recently installed the newest image: RevPi Bookworm 64‑Bit Default (11/2025). However, I’m running into an issue where my device does not appear in the CODESYS → Scan Network dialog.
Here’s what I’ve done so far:

Installed CODESYS Control for Linux ARM64 SL (version 4.19.0.0)
Installed CODESYS Edge Gateway for Linux (version 4.19.0.0)
I can reach the device via ping and SSH
I’m also able to deploy CODESYS products to it successfully

And interestingly my RevPi Connect 4 does show up in the scan network list
But the RevPi Core S does not

Has anyone encountered this issue before or knows what might be causing it?
Thanks in advance!

Hi,
As of RevPi Bookworm (08/2025), the firewall on the RevPi must be configured to allow connections from the CODESYS development environment:

Add the service revpi-codesys to the firewall settings in Cockpit (see Firewall)
If the device still does not appear in the network scan, restart the CODESYS Control service
