Integrated remote control and monitoring systems for primary
and secondary radar sensors, air-ground radio communication systems,
instrument landing systems, airfield "Navaid" beacons
and direction finders, alarm detection, annunciation and reporting,
automated channel surveillance and control, historical data recording
and performance monitoring.

Malaysia (KLIA), Falkland Islands (MPA), Macau and more.
1 Integrated Remote Control and Monitoring for Navaids
1.1 Overview
The SitewatchTM Integrated Remote Control and Monitoring Systems
(iRCMS) for Navaids is a high performance high availability Supervisory
Control And Data Acquisition (SCADA) Master Station software package
which runs on 32 bit workstations and the Microsoft Windows
operating systems. SitewatchTM Master Stations can be configured
for stand alone operation with single or multiple displays, working
as a node on a network or in a fault tolerant configuration with
other Master Stations.
1.2 Operator Interface
The SitewatchTM Human Machine Interface (HMI) is designed for
simple, intuitive and consistent operation over a wide range of
field equipment, allowing the operator to quickly assess process
conditions and rapidly respond to changes. The HMI uses a mouse
as the operator pointing and control device and high resolution
active colour graphics displays to indicate dynamically the status
of the remote site equipment. The display area has a number of dedicated
non-overlapping panels which are used for system alarms and events,
operator log-on, screen navigation and for mimic displays. SitewatchTM uses an advanced 'drag and drop' facility which provides a
direct navigation route from an alarm displayed in the Alarm and
Event panel to the relevant mimic diagram. Mimic displays are configured
in a logical hierarchical format with the operator log on, notepad
and on line help always accessible.
1.3 Field Interfaces
There are existing, proven interfaces to a wide variety of Communication,
Navaid and Sensor equipment. Please see the separate CNS equipment
list in the accompanying PowerPoint presentation. The iRCMS also
provides interfaces to monitor and control the support and service
equipment for the CNS, such as outside electrical supplies, (OES),
diesel generators, Air Handling and HVAC, Low Voltage Distribution
(LVD) systems fire and intruder detection equipment and so on.
1.4 Software Architecture
SitewatchTM takes advantage of the proven advances in hardware
and software technology to harness the performance and reliability
of distributed computing architecture. Sitewatch'sTM
distributed
software base uses a high performance, network transparent 'software
bus' which is built using the inter-processor and client server
features of the Windows operating system. The active object
oriented database encompasses all data and rules relating to a point,
significantly increasing data throughput and reducing system response
times. The object management service incorporates historical data
storage and retrieval as an integral part of the service. Data can
be displayed dynamically on active mimic diagrams, graphically as
trends or in tabular form as process reports. SitewatchTM can
co-reside and exchange data with other Windows compatible
software packages
on a common network, allowing data analysis and report generation
using the customers standard database or spreadsheet software.
1.5 Configuration
SitewatchTM provides the user with a powerful yet simple to
use set of configuration tools which are designed to minimise configuration
times and to ensure that the final configuration is validated and
fully documented. Extensive features are incorporated for on or
off line configuration of animated mimic displays, statistical analysis,
mathematical functions, data import and export and communications
with other system components.
1.6 System Communications
SitewatchTM Master Stations communicate with Remote Terminal
Units (RTU's), Programmable Logic Controllers (PLC's) or other intelligent
equipment's over dedicated lines, Radio, Microwave or Fibre Optic
Links or Switched Telephone Networks using a multi-layered communications
protocol with error checking at each level.
