If
the project encompasses large area to be surveyed and human
surveillance in not possible in such case, then one needs long distance
SACDA radio networks to be employed for sending the data collected from
remote sensors to central unit.
When area under surveillance is hundreds of kilometres such as in case
of petroleum pipeline, the only feasible solution is long distance
Scada GSM. Most important requisite for long range Scada GSMs
is ability to transmit the data to long distance.
For such purposes, repeaters are used as line of sight is limited to 5
miles. Repeaters are radio transmitters which act as boosters for
signals as signals tend to get weak after travelling certain amount of
distance. Thus repeaters boost the attenuated signals and again
transmit them to next repeater/ central system.

There are specific buttons which are associated with
certain buttons and in a moment of time with the interplay of these
buttons, you can generate your SCADA screens. Moreover, some software
allow drag and drop feature for OPC tags from OPC server directly
either via Internet or Ethernet.
One should take best care while developing SCADA screens as the main
purpose of these screens is to monitor the data in a real time and any
major/minor mistake in creation of screen can play havoc with the
output and your whole design can go astray as over representation/
under representation of any type of one parameter can lead to
fallacious results.
Also, one should not be hesitant in using software for creating of
screens as they make the task of creation of error free pretty easy and
one can monitor the data live. |
