DIOS –General System View
The battery-operated Piccolo–XR unit is available in various
models with different options of Inputs and Outputs. The
Piccolo–XR unit can operate DC latch solenoids (outputs), read
status and calculate flow of dry contact meters (inputs).
The units are equipped with built-in radio for communication
with the PIU.
The DIOS automatically builds communication network, using
Store and Forward (S&F) technology, enabling the DIOS to
cover areas larger than normally possible when using a single
radio to communicate with the PIU.
Using the DIOS, the IRRInet system opens and closes stations
(manually or automatically by irrigation programs), reads dry
contact input status, calculates flow rate and accumulates
pulses from water meters.
