Once the connection or
data transfer has been successfully initiated, the software offers a
wide range of data processing, recording and presentation facilities.
be used with up to several hundred remote or local Dataweb modules. As
many as 140 modules (2240 inputs) per location with no limit on the
number of locations.
The software can also integrate data from a wide range of
other acquisition modules and systems, including MSL's
DataScan and Solo modules.
Real time measurement can be maintained despite the remote nature of the
Dataweb, by uploading the logged data on the remote unit. Datweb can
store up to 13000 measurements in it's own logger buffer. This is 36
hours of logging at logging rates of once every 10 seconds. Once the
data is uploaded it is seamlessly appended to the CSS logfile for this
module. Using modem connection times can be minimal ensuring a low
operating cost for the system.
Data logging can be automatically
initiated on a period basis or on an event or alarm basis. (see below)

Real time Trends
The CCS trending facility is powerful and comprehensive. Pan Zoom and
cursor based measurement provide the means by which trends can be viewed
Up to 16 individual trend lines can be viewed through one trend graph.
The time synchronisation feature of CCS ensures that all the clocks on
each Dataweb are synchronised ensuring a high level of time integrity.
Alarms and Events
When an alarm or event is initiated at the Dataweb it can sends an email
to the central CCS system. The CCS picks up this alarm and can then
create a number of automatic activities. It can go into automatic
connection with the remote unit and offer the user a means of viewing
the real time data, it can log and display the data, and it can then
send multiple emails ot text messages to various personnel informing
them of the alarm.
CCS has its own mimic and
display editor providing the facilities to create displays and
user interfaces. Both animated text and graphics can provide high
quality mimic diagrams of the various signals that are being monitored.
Real Time Calculations
CCS provides the means by which the user can configure real time
calculations on the data thereby convert to units or alternatively
provide logical sequences on alarms.
When real-time data is required – for
example, if a mimic with a live update is being viewed –DataWeb Control Centre establishes and maintains the
data link for as long as data is being accessed and
All data is protected from unauthorised access using a
DataWeb Control Centre software provides facilities for
configuring all acquisition and alarm options for every
DataWeb module, using the
familiar on-screen dialog box
Local access to DataWeb

data acquisition and logging facilities. 8 and 16
analog channel versions, with configurable hi/lo
alarm levels, are available, each with 8 additional
digital channels. Analog channels can be configured
for pulse counting in metering Applications.
Access to DataWeb data is via Ethernet (TCP/IP) or
serial link. Data can be accessed live, and there are
General and Event Loggers which can store over
12,000 readings at up to 10 readings/s. Data is
accessed using ftp or http.
Datawebs can be connected together using a 10base T crossover cable
or using a ethernet hub.
