hello,
I would like to know the difference between FF, HART, 4-20ma communication. When I say the transmitter is FF, which means FF is a digital communication protocol, does it mean it doesnt require 4-20ma signal? I am confused between these protocols and signals?
Can I have FF-AI, FF-AO- FF-DI and FF-DO ?
Please advise.
