1. INTRODUCTION
1.1 General features
pGD Touch is a programmable touchscreen terminal designed for
HVAC/R applications. It can be connected over a network to pCO family
controllers, or to any BMS (Building Management System) via a serial
connection, using protocols such as Modbus® or BACnet®. pGD Touch
is an innovative device that simplifies the human-machine interface and
assists the user in browsing the various screens. The terminal can be used
to:
• easily and conveniently monitor operation of a unit or a system from
one or more locations, where necessary with different password-
protected access levels;
• set parameters based on system requirements, for example changing
the time when a device is activated;
• combine building control applications with the Internet and
multimedia devices.
In specific applications, the terminal can be used as:
• a unit terminal: the functions available allow HVAC/R units to be
monitored and managed directly. The terminal can graphically display
the main values managed by the unit in real time, or save these to a
file. These data can then be exported to a USB pendrive or SD card, for
analysis of response times, performance, etc.;
• area controller: the daily, weekly and monthly scheduling functions
allow automatic control over a series of units, managing simultaneous
on/off times or changing set points;
• gateway: the terminal features several serial ports and can be used
to connect together networks that employ different technology and
protocols (e.g. an Ethernet network with BACnet IP protocol to an
RS485 network with BACnet MS/TP protocol).
pGD Touch comes with TFT LCD screen and resistive touchscreen panel,
with LED backlighting (CCFL for the 10” model). The models differ in
terms of screen size (4.3”, 7”, 10”, 13”), communication ports (Ethernet and
RS485/RS232/RS422, configured by software). All terminals feature a USB
port for updating the software and downloading data (logs, alarms).
1.1.1 Programming environment
Users can customise the graphic interface in just a few quick steps using
1tool Touch Editor, an easy-to-use development environment that helps
programmers manage the project. Graphic interfaces can be developed
based on the user’s own drawings in BMP, GIF or JPG format, or using the
SVG (Scalable Vector Graphic) libraries supplied, containing:
• activation devices: buttons, analogue measuring devices, knobs,
cursors, icons;
• components: fans, compressors, filters, heat exchangers, inverters,
valves, etc.;
• system units: humidifiers, fan coils, heat sources;
• CAREL products: sensors, controllers, terminals.
Programmers can simply “drag and drop” the components from a library
to the screen being created: the modular structure means the existing
library of graphic objects and templates can be extended, so as to create
more complete and reusable solutions.
Additional features:
• function simulator: used to get a quick overview on the computer of
what the result will be and the interactive elements will look like;
• remote connection: users can connect to the terminal from their
computer via 1tool Touch Editor Windows Client or Internet Explorer
using ActiveX technology, allowing interaction with the application
program as if they were physically in front of the terminal.
1.1.2 Software functions
In summary:
• send email: the terminal can send an email when a certain event
occurs (alarm or other event);
• IP camera integration: images can be displayed in special windows
on both local stations and via the web, without needing additional
software;
• recipes: users can select different sets of parameters to send to the
controller depending on the part of the program or process being run
by the system;
• “node override” function: if the terminal is connected to a network of
pCO controllers, one terminal can be used to connect to each specific
controller, one at a time, rather than having one terminal for each
controller;
• JavaScript integration: used to implement control algorithms, giving
the terminal its own intelligence;
• multi-language management: each project can contain all text strings
in numerous languages (e.g. Russian, Chinese). The language can even
be changed runtime, together with the type of characters used.
1.1.3 Connectivity
Ethernet connectivity means pGD Touch can be used in an IP LAN. The
use of standard communication protocols (HTTP, FTP, etc.) and client/
server architecture allow remote connection from:
• mobile devices (e.g. tablets): for simple remote control of the main
unit/system functions by end users or service personnel;
• portable computer: for complete monitoring and programming of all
unit or system functions by the manufacturer or service personnel; the
touch terminal can act as a supervisor, becoming the access point for
remote control of the entire installation/building.
