The Industrial Raspberry Pi Forum

Hello everyone,
A few months ago we purchased RevPi Connect+ feat. CODESYS for testing.
According to the Codesys License Manager, the following licenses are activated on the device:
1. MultiCore for CODESYS Control for Raspberry Pi SL
2. CODESYS Control for Raspberry Pi SL
During testing, we encountered a problem that the controller stops working after a while.
The logs show the following error:
ERROR! Demo for IO-Link expired. Feature stopped!

Do I understand correctly that in order to work with Profinet through Codesys, we need to purchase an additional license?
Or does this controller already have all the necessary licenses?

Thanks in advance
Aleksandr

Hello Aleksandr,

you don't need another licence for Profinet.

Did you flash a new image before this problem with the licence appeared?

If you have a Codesys licence and want to flash a new image onto the RevPi, you must first create a backup of your licence.
The following link describes how to back up the licence.

If you have already flashed a new image without securing the licence. Then you must follow the steps described in our FAQ.
