The need to transmit, display and record data is often dependant
upon the particular application needs and indeed whether a suitable
site Scada system is already installed. Nevertheless, many applications
can still benefit from a more proactive approach to data management.
Number crunching exercises can often be avoided if devices are properly
configured. Additionally, operators can be notified in real-time
of detrimental process changes requiring immediate investigation.
PPM BOX technology has many uses; it can be configured for data
collection, data transmission and text messaging when alarm set
points have been exceeded or undercut.
The typical configuration comprises a master and slave controller
with communications between them over a GSM ‘wire-free’
device, using the UK mobile telephone networks as a means to communicate
data and/or text messages. One or more slave controllers may be
connected into the system with hard-wire connection of adjacent
instrumentation. The slave controllers can be programmed to transmit
data on an interval of time or under alarm conditions.
Additionally a “heartbeat” can be sent, typically on
a daily basis, to indicate healthy communication exists. The master
controller which receives the data has flash memory to accept up
to 40,000 records if permanent connection to a PC is not practical.
It can also sequentially page or text up to 10 operators until contact
is made.
The PPM BOX system is also supplied with a comprehensive software
package allowing endless configuration possibilities, in addition
to graphical and tabular data display and archiving.
