Hi,
I am not interested in the relative merits of control protocols. I just want to make the right choice for my scenario.
I am buying an ultrasonic anemometer (2D - wind speed + direction) that offers me a choice of modbus-rtu or nmea0183
I will build a controller to interface to it to collect the data.
My limited understanding on the differences in the choice is:
1. Modbus - My controller will have to poll the anenometer for the data.
2. Nmea0183 - The anenometer will regularly transmit data and my controller will just be listening.
Is that correct?
Thanks,
David.
