AC500-eCo PLC link to Linux Ubuntu 12.04 OS PC for Data Logging.
Has anyone tried to link AC500-eCo PLC to Linux Ubuntu 12.04 OS base PC for data logging?
I would like to know if there are lib file for MODBUS RTU to run in Linux OS.
Yes, there are several modbus libraries available for unix based OS. Start here http://libmodbus.org
There are also some good application examples of connecting the AC500 PLC to both Modbus comms and via TCP to an SQL database here www.abb.com/plc
So "in theory" it is quite possible. But i will admit I have not done this. Im not aware of any finished off-the-shelf product you can buy, so I guess you will be looking at writing a lot of this yourself.
You could also ask about the unix side of things on www.control.com There are several regular posters there who write open source unix software
