(March 2016) ( Learn how and when to remove this template message)( Learn how and when to remove this template message)Supervisory control and data acquisition ( SCADA) is a system for remote monitoring and control that operates with coded signals over communication channels (using typically one communication channel per remote station).The control system may be combined with a data acquisition system by adding the use of coded signals over communication channels to acquire information about the status of the remote equipment for display or for recording functions.

[1] It is a type of industrial control system (ICS). Industrial control systems are computer-based systems that monitor and control industrial processes that exist in the physical world. SCADA systems historically distinguish themselves from other ICS systems by being large-scale processes that can include multiple sites, and large distances.

[2] These processes include industrial, infrastructure, and facility-based processes, as described below:� Industrial processes include those of manufacturing, production, power generation, fabrication, and refining, and may run in continuous, batch, repetitive, or discrete modes.� Infrastructure processes may be public or private, and include water treatment and distribution, wastewater collection and treatment, oil and gas pipelines, electrical power transmission and distribution, wind farms, civil defense siren systems, and large communication systems.� Facility processes occur both in public facilities and private ones, including buildings, airports, ships, and space stations.

They monitor and control heating, ventilation, and air conditioning systems (HVAC), access, and energy consumption.

They have telemetry hardware capable of sending digital data to the supervisory system, as well as receiving digital commands from the supervisory system. RTUs often have embedded control capabilities such as ladder logic in order to accomplish boolean logic operations. [3]� Programmable logic controller (PLCs) connect to sensors in the process and convert sensor signals to digital data. PLCs have more sophisticated embedded control capabilities (typically one or more IEC 61131-3 programming languages) than RTUs.

PLCs do not have telemetry hardware, although this functionality is typically installed alongside them. PLCs are sometimes used in place of RTUs as field devices because they are more economical, versatile, flexible, and configurable.� A telemetry system is typically used to connect PLCs and RTUs with control centers, data warehouses, and the enterprise.

Examples of wired telemetry media used in SCADA systems include leased telephone lines and WAN circuits. Examples of wireless telemetry media used in SCADA systems include satellite (VSAT), licensed and unlicensed scada system for water treatment, cellular and microwave. [4]� A data acquisition server is a software service which uses industrial protocols to connect software services, via telemetry, with field devices such as RTUs and PLCs.

It allows clients to access data from these field devices using standard protocols.� A human�machine interface or HMI is the apparatus or device which presents processed data to a human operator, and through this, the human operator monitors and interacts with the process. The HMI is a client that requests data from a data acquisition server or in most installations the HMI is the graphical user interface for the operator, collects all data from external devices, creates reports, performs alarming, sends notifications, etc.� A historian is a software service which accumulates time-stamped data, boolean events, and boolean alarms in a database which can be queried or used to populate graphic trends in the HMI.

Jan would lament "Marsha, Marsha, Marsha". As you peruse through trade journals and magazines, you see article after article on SCADA. Like Jan, you could lament "SCADA, SCADA, SCADA". From this plethora of articles you can get the feeling that SCADA is the "Go-To" tool for water and wastewater control. But is it?The simple answer is yes, maybe, and no. SCADA is a tool with a very specific defined set of functions. SCADA can: turn devices on or off, display real time operational data, provide equipment-wide to system-wide views of operation, trend data, and alarms.

If this is all you want then SCADA is your tool, and the answer to the question above is "Yes". What is SCADA not intended to do?SCADA is a real time tool. It is not supposed to be a tool for detailed analysis of past performance. Of course, you may need to know something about past performance to be able to react to current conditions. Thus some form of trending is included.

The trending function is as close to analysis as most SCADA softwares get. [Native Advertisement]Let's say a water treatment operator wants to look at chemical usage in three GAC filters and determine how each filter behaved over the past six weeks. In this case, SCADA is your tool of choice. Some SCADA let you look at these three filters and compare their performance with some time period in the past.

What if you want more analytical capability?As stated, SCADA, by design, is limited in its data analysis tools. If you want more, then you have a variety of options.

One is to install something called a historian. A historian sometimes called an Operational Data Management System (ODMS), bolts onto a SCADA and has expanded analytical tools for trended data.

Some people believe a historian is just an expansion of the SCADA trending tools, however a historian can look at any data in a database even if it was not collected via the SCADA system. Use of a historian, or ODMS, is already a mainstream feature in large to extra large facilities, and is quickly being adopted by many small to medium size facilities.To continue the analogy above, what if you wanted to graphically see how the three basins operated during the period between Thanksgiving and New Year's for each of the past six years?

Most SCADA systems are not capable of doing this. So, the answer to whether or not SCADA is your "Go-To" tool is a "Maybe". But, a historian can do this.

Of course, the historian is still just reporting data, it is up to the operator to find a way to analyze that data, and remove the unwanted data.Water Management Suite (WMS) interconnection map.For instance, when the filters mentioned above are backwashed, then the turbidity spikes.

This data point might register as the maximum turbidity detected in a historian report, but this is not a relevant piece of operational data. In order to find the true relevant maximum, an operator would have to eliminate all the turbidity spikes associated with backwash to find the true maximum.

SCADA is not designed to handle this task so the answer to the "Go To" question in this instance is "No".Traditionally, obtaining this requires taking raw data and exporting it into a customized database. Does this sound like a lot of work, with some potential problems? Yes it does.First, the database has to be developed. Some of the larger plants have internal staff that is capable of doing this.

Others may rely on external developers. Once facility staff see what this tool can do, they tend to want to add their own items. These homegrown tools tend to evolve overtime as different needs are bolted on, which may cause thThis website uses cookies to store information on your computer.

Water purchased from the San Diego County Water Authority is distributed to businesses and residences. Delivery of the potable water requires little to no pumping, as the water travels via a gravity feed from large storage tanks.Carlsbad�s SCADA system has been configured to control various equipment and monitor the water throughout this entire process. Analog and digital input and output modules connect to:� Level transducers that track water levels in large reservoirs and tanks.� Pressure transducers in pipes that measure pressure in pounds per square inch (psi) within each zone and ensure that water is pumped and is flowing efficiently as it�s being delivered.� Flowmeters that measure how many gallons of water per minute are being delivered.� Pressure-sustaining, pressure-reducing, and other valves that open and close incrementally to adjust the rate at which the water flows.

[Native Advertisement]Technician Tom Pagakis oversees the SCADA systems that monitor and control all water and reclaimed water for the city. The key components for these systems are SNAP-brand controllers manufactured by Temecula, CA-based Opto 22.The City of Carlsbad SCADA system monitors transport, and distribution of purchased water from lakes and reservoirs to the city; and reclamation of treated water.�We started using Opto as an experiment,� Pagakis said.

�Years ago, we were using outdated technologies like tone telemetry and later, a mix of I/O modules and systems from other vendors. Special drivers had to be created to make everything communicate and it had become very complicated and unwieldy.�The SNAP systems � which communicate with each other and back to the control center through a combination of radio, serial, and Ethernet links � are used to monitor, control, and acquire data from all of the city�s water and reclaimed water systems.

Pagakis regulates all water transport, monitors an independent water treatment plant, and controls the chemical dosing of ammonia and chlorine that cleans the water. In total, these activities incorporate more than 1000 I/O points distributed across the city�s command and control center and numerous remote sites.�Currently, the SCADA system encompasses three large reservoir impounds, 14 reservoirs, and 20 pressure-reducing stations used to monitor more than 500 miles of distribution pipeline,� Pagakis said.Significantly, all of the monitoring and data acquisition functions are performed not by a single (or even multiple) central controllers, but by local I/O processors (or �brains�) distributed at pump stations and other points across the city�s infrastructure.

These brains communicate to I/O located on the same rack and perform functions normally reserved for an expensive PLC.For example, the brain takes valve readings from the analog input modules and performs scaling calculations to convert a voltage measurement into a percentage.

So, for a typical 4-20 mA analog input module, a measurement of 12 volts would result in a reading of 50%. To have this scaling and engineering unit conversion take place locally, at the I/O level, relieves the main controller from extra processing, while also providing control center personnel the convenience of being able to view and interpret easy-to-understand units of measure (i.e., percentages as opposed to voltages.)Distributing intelligence in this manner also provides a safeguard in case there�s an interruption in the operation of one of the scada system for water treatment controllers.

The brain can be instructed to continue to record measurements and perform calculations, and operators can continue to vieWiztech Automation Solutions +91 99404 26826.

The term SCADA system can be used to describe a multitude of computer-based control systems that allow operators and facility personnel to monitor and control a facility�s equipment either locally or remotely. Typically, a SCADA system will automate much of the control process such that plant operators can focus on other task.

The systems we design give the operator flexibility to manually control the equipment where desired. SCADA systems are also installed to collect and store information for reporting, troubleshooting, maintenance indications, and much more.There are a number of advantages to having a SCADA system installed such as:�Ability to significantly reduce operating costs, while improving system performance and reliability�Costly after-hours alarm call-outs can often be avoided since a SCADA system will indicate the nature and degree of a problem�Since data is continuously recorded, operators do not have to manually read and record meter readings on a daily basis.�Operators do not have to keep track of hundreds of log sheets as any data recorded on the SCADA system can be downloaded and accessed at their convenience.�SCADA systems can often be accessed remotely through an internet connect on your office computer or laptop, and even your cell phone or tablet. SCADA systems can range from the very basic to the extremely complex.

A well designed SCADA system can make the most complex configuration both user friendly and easy to maintain. Back to news listing RECENT ARTICLES� USCG & TSA REQUIRE BIOMETRIC SECURITY BY 2018� SECURITY PROJECT GETS NATL.
