Prolog Lite is an environmental monitoring system from Contronics Limited that monitors up to 100 sensor points across multiple sites. It consists of a central Prolog Lite server and InfoPoint display, networked via Ethernet to remote DataNodes that collect sensor data. The system provides real-time alarm notifications, historical data logging, and role-based access via the Control Program. Users can configure sensors, set alarm thresholds, and accept alarms from any networked PC.

The Control Program can
also display and print
composite trend graphs
showing all the sensors
connected to any piece
of equipment for any
timeframe . . .
The Control Program
can sort the
complete audit trail
back to system
switch-on by
timeframe, event
type, equipment,
sensor and
department . . .
Alerter
The Alerter is a pop-up application. It can be installed on
any PC with access to the network. Users can configure
the program to respond
only to alarms from
relevant departments.
Alerter provides real
time audible and visual
indication of alarm
conditions. The pop-up
display mirrors the alarm
information displayed on
an InfoPoint.
A remote user can accept alarms using the Control
Program. The audit trail is maintained whether the alarm
is accepted using the InfoPoint or the Control Program.
Working together
We work closely with our customers from the initial user
requirement specification through to system acceptance.
We can temperature map your equipment and provide
documented justification for sensor positions.
Our engineers will install, commission, calibrate and
validate your system and train your staff. We will work
with you to generate the qualification protocols you need
to satisfy your regulatory requirements.
Support you can rely on
A one year, on-site, parts and labour warranty
demonstrates our confidence in our systems.
On-going maintenance agreements preserve your
investment in Contronics systems. We look after
preventative maintenance and scheduled annual
calibration, validation and mapping and prepare a
comprehensive documentation pack ready for your
regulatory inspection.

Prolog Lite
Prolog Lite is the latest addition to our world-class range of
environmental monitoring systems. The system is 21CFR11
Part 11 and GAMP compliant and will satisfy MHRA
requirements. It is a multi-user system with the capacity to
monitor up to 100 points distributed over multiple sites. It
monitors a complete facility whilst maintaining departmental
separation and responsibility. Prolog Lite combines the server
and InfoPoint in a single, wall-mounted unit.
The server uses an industry standard MySQL database. It
stores the system configuration information and accumulates
measurements from DataNodes. It also maintains a secure
audit trail of alarms, alarm acceptances, settings changes and
all system events and actions taken. Prolog Lite makes
scheduled automatic database backups to a nominated server
on the network.
The system is highly resilient. Logged data is duplicated in
the database and in DataNode. If the network connection to
DataNode is interrupted, missing database information will be
automatically retrieved when the network connection is
restored.
The system generates four alarms per sensor; upper and lower
warning levels and upper and lower alarm levels.
Prolog Lite will send email containing detailed alarm
information to predefined addresses: including smartphones.
Separate addresses can be defined for each department.
Departmental responsibility is achieved by configuring
InfoPoint displays to respond only to alarms for specific
departments.
As shown in the diagram above, Prolog Lite is connected by a
standard Ethernet network to distributed DataNodes which
collect and store data from local sensors. Local InfoPoints
display alarms and information only from equipment for
which the department is responsible.
ProLog Lite software is being continuously developed to
reflect the changing needs of users and to ensure that the
system complies with current legislation and practice.
Software updates are offered free of charge during warranty
and subsequent maintenance agreements.
InfoPoint
The 17”, wall-mounted, colour LCD touch-screen display and
intuitive user interface mean that InfoPoint is simple to use,
easy to understand and minimises training.
InfoPoint displays alarm conditions, current sensor values and
settings, audit trail information and trend graphs.
Alarms can be accepted, channels can be inhibited and
temporary disables initiated (eg for defrost). All the
frequently used system operation and maintenance functions
are included.
InfoPoint uses an index card metaphor to simplify navigation.
Touching the tab at the top of the screen changes the display
mode.
When an alarm occurs, InfoPoint generates an audible and
visual alarm, jumps to the alarm tab and displays the alarm
information and advisory text . . .
Username and password are necessary to accept alarms and a
user comment is required for the audit trail. These are
entered using the on-screen keyboard . . .
Sensor data is displayed graphically . . .
An image can be
inserted on the status
page to provide more
information . . .
InfoPoints can be
distributed
throughout a facility
as required and alarm notifications can be transferred to a
different InfoPoint when a department is not staffed.
InfoPoint’s UPS ensures operation is maintained during
changeover to emergency supply.
DataNode
DataNode accepts up to 16 analogue inputs, 16 contact
inputs and 4 serial inputs. In addition, 8/4/2 analogue input
versions are available to minimise system cost for smaller
applications. The minimum logging interval is 1 minute.
At this setting, DataNode stores 1 week of local data.
DataNode makes continuous analogue sensor measurements
at 1-second intervals and stores the worst excursion during
the logging interval in the database. It accepts a range of
inputs as shown in the specification on the back page.
The serial inputs interface with particle counters and other
intelligent sensors.
DataNode has 4 relay outputs. These can be configured to
change state for any combination of alarms and used, for
example, for local alarm indication.
Each channel (or piece of equipment) can be configured to
include up to 4 analogue or serial inputs and 4 contact inputs.
A UPS is installed to enable DataNode to continue logging if
the mains supply fails.
Control Program
The Control Program is used to configure and control a
ProLog system. The Control Program is a web application;
this means that any PC on the network can access this
program using a familiar web browser.
The system manager specifies the users who have access to
the system and attaches users to departments.
Usernames, passwords and the required level of access
permissions are allocated to users so that they can configure
and maintain the system, accept alarms and alter settings
within their designated departments.
Details of alarm acceptances, settings changes and any other
interventions are recorded in a secure audit trail along with
user’s name and comments.
A channel is configured for each piece of equipment attached
to the system. Sensors are assigned to a channel and upper
and lower warning and alarm levels are set. The channel
names, sensor names, alarm messages and optional channel
and sensor advisory text are entered. The equipment supplier,
part number and serial number are also recorded . . .
