Industrial Applications of SCADA systems

Industrial Applications of SCADA systems

 What is SCADA ?

SCADA (Supervisory Control and Data Acquisition) system in a simplistic approach can be defined as a supervisory control system which monitor inputs and initiate the output action based on associated logic for input events. The traditional way its done by small industries are using manual human controlled actions. Installing automated SCADA system lets industries monitor and control the system using automated tools whose accuracy results in lowering production costs and in the long run turns out to be beneficial for the company.

SCADA systems can be bought from reputed companies and customized with additional costs to suits the Industrial manufacturing system or cost effective alternative is, in-house development of such systems as per the need of the industry.  As in-house development of SCADA systems requires expertise, Argus Systems unique “Design your own Product (DOP)” program, lets you acquire the expertise of dedicated individuals and helps you in creating products from custom requirements.

Industries where SCADA systems can be deployed  ?

SCADA Systems plays vital role by providing utilities for various Industrial application and are useful in Oil & Gas, Petroleum, Food, and Textile, telecommunications, water and waste control, energy, solar and transportation. A SCADA system for power companies ensures delivery of power in a reliable and safe manner. SCADA system for oil and gas industry has remote data collection, real time processing, storage, alarming, display, call-out and reporting capabilities. The SCADA capabilities can be further utilized to monitor grid protection relays, stations monitoring weather, energy meters, transformers, DC switches and Valves.

Architecture of SCADA systems

A SCADA system typically consists of four major elements:

  • Master Terminal Unit (MTU) :  The MTU initiates all communication with remote sites and is situated at operator’s control site.
  • Remote Terminal Unit (RTU):The RTU is located at the remote site and is responsible to gather data from field devices like panel, valves, alarms, etc. and keep them in memory until the MTU initiates command to send.
  • Communication Equipment: For MTU-RTU communication the system can employ more than one means including dial-up, DSL, ISDN, Ethernet, fiber optics, Wi-Fi, or any other broadband services.
  • SCADA Software: Typical SCADA system software provides a HMI or Human Machine Interface for the operator to visualize and control all the functions of the system.

Overall data acquisition is performed at the DC level as well as AC level. Different methods may be used for communication to the SCADA via ModBus. Both DC and AC side parameters, status and diagnostics can be continuously acquired by SCADA monitoring system.

PCB Design Challenges in SCADA System Design

The Industrial environmental conditions (significant radiated  and conducted emissions due to switching of heavy electrical/electronics cards) makes the SCADA product development quite challenging in terms of systems susceptibility for the harsh environmental conditions as well as ability to run the system with lower noise margins.

All the SCADA systems has ADC and DAC as their building blocks requiring lower noise floors for their proper operations which in turn requires special attention in electronic designs of the system.The SCADA systems usually  would have multiple communication interfaces running over longer lengths of external cables posing severe challenges for ESD/EMI compliant design.

ACTIVE NOISE CANCELLATION (ANC) Headphones

ACTIVE NOISE CANCELLATION (ANC) Headphones for Defense/Military Application

In high Integrity electronic products which  caters  the need of  military and civil aerospace application unwanted environmental noise can cause distraction and can amount to loss of human resources as well as  major economic losses .  The unwanted sound can be reduced by using passive noise cancellation also known as noise isolation  or by using  active noise cancellation (ANR) /Active noise reduction (ANC) headphones.

Passive noise isolation fundamentally tries to block the offending sound wave by creating physical obstruction between the ears and the sound. In-ear canal and closed back headphones are few examples of headphones which are successful in reducing ambient noises by 8 to 12 dB.

Active noise-cancelling headphones uses two fundamental blocks that is the block which captures the sound and a speaker to amplify and play the sound in phase reversed form so that the the unwanted noise cancels out. ANR is the most effective defense against low-frequency noise like noises generated by engines, blowers, motors, fans, vacuums, pumps, generators and other similar devices are typically dominated by low frequencies —frequencies that cannot be stopped by passive earmuffs.

What are PCB test Jigs, test Fixtures and ATE?

Why PCB Tests are required

Any electronic product even if properly designed and built with utmost care is prone to bug and issues. It is very crucial to test the product or PCB thoroughly in early stages of design to save millions of dollars later. The testing can be done at PCB design level wherein after using various design analysis techniques like EMI, Signal Integrity and Power Integrity, the design issues can be minimized. But how do you test the PCB once bare- board PCB is in your hand or after components population i.e. assembly has been done? How do you make sure that there are no shorts, open or bad solder joints? How to make sure current capacity, performance, component value and Impedance are within proper and expected tolerance level?

What are PCB Test Jigs and ATE?

Also we should know and comprehend the common terms used in the Electronics hardware testing domain. Specialized and custom designed Test jigs and fixtures are used to test pcb. Test Point are identified and probed to identify the input to be given and output to be measured. A test jig can be identified as a device or machinery that holds a piece of machine work which now a days comprised of much electronic intelligence and guides the tools operating on it. It should not be confused with Test fixtures which are used to keep the object firmly in place. However, in PCB testing both the terms test jigs and test fixtures are interchangeably used as is meant as a electro-mechanical solution to test the printed circuit boards or PCB’s. Custom made Test jigs and test fixtures are made as per the application of the board to test its test points. Automated Test Equipment (ATE) are those apparatus which makes these tests automated and help to identify issues even at System-On-Chips and Integrated circuits levels. So how do we test PCBs ? we use test jigs, test fixtures and ATE to test the Printed circuit board.

Board testing at various levels

  1. Bare-Board Tests
  2. Assembly Level Tests

Bare-board tests

Bare-board test are the tests done on unpopulated boards where netlist defined circuit connection is verified properly on the fabricated board. A small voltage is applied and is verified at the appropriate points, a “short”, “open” are identified in these types of tests. Industrial CT scanning can show details of soldered path and connections by generating a 3D rendering of the board along with 2D image slices.

Assembly Level Tests & Functionality Tests

After the board has been properly assembled it may be tested in a variety of ways using either manual inspection or using expensive Automatic test equipment (ATE).

Automatic test equipment enables PCB test, and equipment test to be undertaken very swiftly. Automatic test equipment is quite expensive, and therefore it is necessary to select the proper type suitable for the application and board to be tested.

In-Circuit Test, ICT

In-Circuit Test, ICT is a form of ATE is very effective form to test printed circuit boards. It can find short circuits, open circuits, component values, and it can checks the operation of ICs.

JTAG boundary scan

JTAG boundary scan uses the dedicated test logic built into Integrated circuits (ICs), to check if each device is correctly soldered and is properly inserted onto the PCB. The devices which include this logic are FPGAs, CPLDs, microprocessors, DSPs, bus logic, SERDES, telecom encoders, PHYs, ASICs, and Bridges (PCI/PCIe).

Functional tester

When the function of the circuit is tested it is known as Functional test. Functional testers typically interface to the PCB or device under test via its test-probe points or edge connectors. This testing is the simulation of the final environment in which the PCB is meant to function. The test equipment can be chassis or rack based or test equipment which uses GPIB.

A company which has specialized knowledge on various aspects of PCB tests, can be in assistance of OEM and suggest the best test method and test equipment to improve and test the product reliability , defect and issues early in the product life cycle and can thus save both  the product development crucial factors cost and time.
