Hi,
Currently we can configure up to 2 port for i2c.
Could you teach us how to set 3 port i2c?

from CODESYS side you have two possibilities:
1. either change the device desciption of the PI MC device - allow more than 2 I2C
2. or use the I2C which some other user use on Beaglebone from here:

Sure on Pi OS side you need probably changes too to have 3 x I2C available or do you have this up and running already?

Yes, I could set and run x3 i2c using belowdevice.xml in our system.
