I've been researching the RPi learning environment for a few weeks now ... Being a teacher to high school Electronics and ICT students. I'm supposed to teach them the basics of IEC 61131-3 PLC programming. That is why I'm very happy I found Codesys. It allows me to bring PLC in to their comfort zone. (Raspberry Pi, Arduino, I2C, SPI, ...)
I'm wondering now ... When I take Gerhard 's Arduino Uno IO Driver in the IO mapping page I can map variables to physical Arduino pins. When I take a look at the PCF8574 library supplied by Madax. The communication is byte wise oriented using:
