The issue with numerous errors 8455 by IoDrvRevPiBridge is now resolved with the Revolution Pi Library for CODESYS V2.5.0.0 (I/O Driver for the Integration of Revolution Pi Devices in the CODESYS Development System V3.5 SP21), available for download on the official downloads page:

Hi,
Thank you for bringing this issue to our attention with detailed logs and context!
We have identified the root cause. The error 'Update Module Reset Counter state failed' (ErrorCode 8455) is triggered by a type mismatch in the internal reset-counter lookup: the module's process-image offset was ...

Hi Will,
Please work through the following steps in order:

1. Power cycle the DIO and reset piControl
First, switch off the 24V PSU feeding the DIO's X2 and X4 connectors completely — do not just do a software reset. Wait at least 10 seconds, then power back up. This procedure clears any latched ...

Das venv ist der richtige Weg — --break-system-packages sollte man vermeiden.
Keine Probleme zu erwarten: SocketCAN (can0, can1) ist systemweit verfügbar und vom venv unabhängig.
Für den automatischen Start beim Boot empfiehlt sich ein systemd-Service, der den venv-Interpreter direkt referenziert ...

Yes, the workaround is a USB-CAN adapter (e.g., PEAK PCAN-USB or any gs_usb-based device) connected to the bus with 120Ω termination at both ends. This gives you a second node on the bus that provides the missing ACK, with no additional drivers needed on Linux.

Since can0 is already the onboard ...

Hi,
Unfortunately, PiCtory does not support custom I/O sizes for the EtherNet/IP Gateway or in General other Gateways. — the dropdown is fixed to 20 and 480 bytes, and there is no way to enter an arbitrary value like 8 through the UI.

The recommended workaround is to configure both sides for 20 ...

Hi,
Unfortunately, neither one-shot nor presume-ack is supported on either platform.
Connect S + ConCAN
The driver for the ConCAN controller does not expose these control modes via SocketCAN.
Connect 5 (built-in CAN FD)
The same limitation applies. On the Connect 5 running the Bookworm image with ...

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 ...

Hi,
I suppose you are using the Revolution Pi Library for CODESYS V2.4.0.0.
MIO bit access for outputs works when the module is connected to the Connect 5 on either side over piBridge.
Perhaps you have a specific module combination where this issue is occurring. An SOS report would be helpful.
Also ...

Thanks for sharing with the community!
