Radio communication scada products

Converters and on its basis the system reacts to a particular state. PLCs can be easily programmed. The SCADA system like in all systems also keeps a record of data collected in database in a systematic way and can be easily accessed and manipulated.

Thus, when one needs to locate the fault he can easily locate by checking the parameters which are stored in database. As the faults gets detected in a timely and efficient manner, SCADA in the water industry also saves troubleshooting costs which can be huge if there is no idea of the location f the fault.

Data transmitted from remote sensors to central unit can be done in many ways (Ethernet, serial ports, wireless) but wireless mode of transmission is always cost effective and efficient. Thus, it can be concluded that SCADA in the water industry has proved to be a boon paying for the efficient and reliable working of water control systems.

SCADA VHF Industrial products generally work as remote sensors or repeaters. As the name suggests, these products operate at VHF (Very High Frequency) which are of tuning of Mhz.

Thus, the frequency band allocated to SCADA VHF industrial products doesn't cause interference with other equipments operating in this range. SCADA VHF industrial equipments too work on the same principle of remote units and central system. Remote units collects the data and send the collected data to a central system where its gets processed and is displayed at Human Machine Interface (HMI) in human readable format as series of graphs and textual representation.

If these radio transmitters act as remote units, then they collect the data and send it to a central system via a wireless system operating in frequency band of 175- 900 MHz, as the maximum capability of these units is transmission in line of sight (maximum distance at which central system is visible), it comes to be a major limitation of this excellent automated system.

These systems can be seen serving electricity control systems, sewerage control systems and such have been trust which has been entrusted with these systems that now SCADA in the water industry has become inseparable part.

With the deployment of SCADA in the water system the maintenance costs have reduced to great extent along with the time taken to diagnose the fault. The underlying principle of SCADA in the water industry is same as of SCADA systems in general.

There are present remote sensors which collect the data and via a transmission media send the collected data to a central system which carries out the task of management, processing and display of the collected data in human readable format. The data gets displayed at Man Machine Interface, also called MMI. The brain of every SCADA system lies in PLCs which is acronym for Programmable Logic.
