I would like to bring in the Omega 2 into the Industry. For that I was thinking about building a Modbus RTU dock. But I have some Problems. I'm not that familier with linux and I tried useing libmodbus, but running into the disk space problem does someone have a better Solution?
It works perfect now, but it seems noone is interessted :(
@Fabian-Nydegger Interested, sure! Just no immediate application for it ;-)
I'm using Omega2 in my building automation devices already, but no Modbus (yet).
What is your application?
simply download https://pypi.python.org/pypi/MinimalModbus and opgk python, get any Rs485 converter https://www.sparkfun.com/products/9822 and test it. The dokumentation is very good also for beginners in modbus. I'll make a dock and case soon.
I did not realize Modbus is RS485.
Does this mean that I already built a triple Modbus dock by accident by doing this? ;-)
(3 RS485 interfaces, Ethernet, 5..39V to 3.3V regulator, fitting into nice small Hammond 1591XXA case - designed to control Swiss Railway split-flap display modules)
Yes if it's rs485 you just need to configurate the protocol, but remember most ModBus devices runs on 24V
