I need to create a small self contained remote logging unit that will read 10 or so of the 03 registers from a modbus slave. The information is updated by the slave every 1.5 mins. I then need to log this data to an SD card. Ideally I would want to then be able to plug the unit into a USB port on a PC and pull off a txt file with all the logged data on it.
Everything needs to be housed in a small enclosure.
Is this something that can be done with the Uno board or am I barking up the wrong tree completely ?
Thanks for your help
