INTRODUCTION

Scope of this Manual

This manual provides instructions for the installation and
operation of the Distributed I/O system Piccolo Interface
Unit (PIU) and Piccolo–XR units. The Distributed I/O
System includes PIUs and Piccolo–XRs. Each PIU can be
linked to up to 256 Piccolo–XRs. For more information on
the PIU and Piccolo–XR, see the online help of the DIOS
Service Toolkit.

General Description

The Distributed I/O System (DIOS) is a self-sustained
system designed to function within the IRRInet irrigation
control product line.

The DIOS consists of the following components:

• Piccolo Interface Unit (PIU)

• Piccolo–XR Units

The PIU functions as an interface between the host
application (irrigation SW and HW) and the Piccolo–XR
units. The PIU and Piccolo-XR are portable devices, which
are commonly used in fixed installations. The PIU uses
one of its communication ports to link to the host
application and radio communication to link to the
Piccolo–XR units. Figure 1 provides a general view of the
DIOS System.

I/O's

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.

Introduction

PIU - Piccolo Interface Unit

The Piccolo Interface Unit (PIU; see Figure 2) is connected
to the IRRInet Field Unit (FU) via RS232
or RS485 serial ports.

Each PIU supports up to 256 Piccolo–XR units, with any
available I/O combination, limited by the capacity of the
IRRInet software only.

Utilizing the S&F technology and networking capabilities,
the PIU can be linked to Piccolo–XR units positioned in
distances of up to 1500-2000 meters (approx. 1 mile),
depending on topography, antenna type and antenna
installation.

The PIU is an interface between the Piccolo–XR and the
IRRInet FU, which provides communication and
networking operations only. (Monitor and control features
are not included in the PIU.) That is: The control and
monitor functions are provided either locally, by the
Piccolo–XR or by an upper hierarchy unit (i.e. IRRInet
FU).

The PIU is a portable device, which is most commonly
used in the fixed installations enclosed with an indoor
plastic housing.

The PIU must be installed by qualified and authorized
technicians, so as to meet applicable safety standards and
to ensure protection against weather hazards for the unit.

If the PIU will be connected to outdoor lines, an interface
unit, complying with Clause 6 of the UL 60950 standard
must be provided.

Introduction

Figure 2
PIU – General View

Piccolo–XR

The Piccolo–XR is an intelligent, microprocessor based
unit that can be used to monitor and control local units in a
multi unit communication network. Piccolo–XR units
communicate data to a PIU while functioning as intelligent
nodes in Distributed I/O monitor and control systems. The
Piccolo–XR is often used in irrigation and water
distribution systems (i.e. irrigation valves, water meters,
fertilizing meters, various sensors, flushing filters, and
other non-irrigation devices).

The Piccolo–XR is ideal for use in applications where very
low power consumption is essential. The Piccolo–XR is
also available in an outdoor resistant housing (IP66),
designed to resist harsh environment, such as exposure to
sun, dust, and pouring rains.

INSTALLATION

General

SAFETY SUMMARY

The PIU and Piccolo–XR must be installed by
qualified and authorized technicians, specifically
qualified to handle high voltage if the installation
involves high-voltage connections/installations.

If the PIU will be installed outdoors, an outdoor
plastic housing complying with UL60950 standard
clause 6 is required.

Note!

Note!

See Piccolo–XR Screw Mounting Options (pg 19)
for mounting details.

This equipment is tested with specified length
cables and in standard enclosure. If longer
cables or a different enclosure are used, the
installer is responsible to ensure that the
installation complies with the requirements of the
applicable standards.

Installation

Before installing the PIU, verify that there is sufficient space
around the unit according to the specific installation.

Mounting the PIU On A Wall Using Screws

Secure two screws (not supplied) of maximum 0.37” (9.5 mm)
head size to the wall, 3.256” (82.7 mm) apart. The wall­mounting template in Appendix D can be used to determine the
space between both screws.

The screws must not protrude from the wall surface by more
than 0.23” (6 mm) or by less than 0.16” (4 mm).

Attach the unit to the wall, fitting the two shaped cavities on
the back cover of the unit over the screws and sliding it down.

Appendix C: Antenna

Pole Antenna

The pole antenna installation must comply with the
following requirements in order to ensure optimal
performance and guarantee human exposure to radio
frequency electromagnetic energy is within the guidelines
set forth by the applicable local regulations.

The antenna must be mounted outdoors, preferably on a
tower, if possible.

Building mounted antennas must be located on the building
roof.

All fixed site antenna installations, including the
installation of this pole antenna, require that, under the
responsibility of the licensee, the installation site be
managed in accordance with the applicable regulatory
requirements. This may require taking additional
compliance actions such as signage and site access
restrictions in order to ensure that human exposure limits
are not exceeded.
