The future of Industrial automation PLC SCADA technologies

Every industrial automation PLC SCADA project starts with the familiar process of counting I/O, selecting vendors, laying out PLC chassis, and distributing requests for quotes. And finally you are commissioning a system built on general standards, repeating the same mistakes as previous systems.

The conversations also repeat during bid review or negotiation meetings when someone points out inconsistent or outdated standards. Technology is changing so fast, and the past few years have brought technical advances that have breathed new life into Industrial automation groups and started great discussions around what the future holds. There is still a lot of work to be done.

Virtualization is a great example. Early adopters saw the benefits, and news spread like wildfire. As SCADA (supervisory control and data acquisition), manufacturing execution systems, and historian capabilities increased, so did the need for processing power, and virtualization was the perfect answer. Virtualization is now commonplace in Industrial automation domain. And many are asking what is next. The next big thing is waiting to happen. Industry has become more demanding asking for virtualized controllers and solution with mobility. But they are easily feasible with existing technology. The success of our industry depends on it.

HMI/PLC SCADA industrial automation applications have already secured their place as key components for any smart factory, IT-focused applications. Humans by nature are reluctant to give up control; however, fully automated facility does not mean a complete end of human interference on the factory. Considering the huge focus in industrial automation / automated equipment and intelligent HMI/PLC SCADA software, it is important that manufacturers invest in employee training, enabling talented engineers from industrial automation domain to focus on important tasks.

What is Industrial automation & how it evolved

What is industrial Automation

Industrial Automation is a technique by which we make hand over human control to machines. In industrial automation machines are programmed to accomplish the tasks which human beings used to achieve. Why it is done? Because of its advantages:

• Through Industrial automation we are able to do mass production with less manpower

• Quality of the product is increased
• Safety of man & equipment is increased
• More accurate process control
• Since human intervention is less so reliability of the system is higher
• Systems operate is low power supply, more electronic control so equipment life is higher
• Changes in process logic becomes easier since logics are changed mostly through software

How industrial automation control system Evolved?

Initially automation was achieved through manual control, operators used to control the process at every step. Human intervention was there at every step. Drawbacks were low quality output, errors involved in human involvement affected compromised safety, wastage of raw material, and accuracy of human action.

Then came Pneumatic Control: Industrial automation in this era was achieved through invention of pneumatic controllers in early 1920s. Automation was achieved by controlling air to pneumatic valves, which in turn were actually switched on/off by relays and switches. They were very bulky and changing of the logic was very complex procedure since a lot of rework was required to accomplish change in logic. So time taken to complete task changes was very high  

Hard wired logic control: contactors, relays (for switching), timers and counters (for timing and counting) were used for achieving desired industrial automation. But these systems also resulted into bulky panels. A lot of wiring was involved so time taken to complete task was higher. Defect investigation & troubleshooting was complex.

Electronic Control using Logic Gates: In early 60s electronics dominated the process, electronic logic gates were used for achieving logical operations. they replaced switching devices like relays and contactors in the control circuits. Electronic times & counters replaced mechanical timers & counters. Due to use of electronics space and energy requirements reduced, maintenance requirement reduced & systems were more reliable.

Psychometric study and HVAC design and drafting

Psychometric study is a vast science and an integral part of HVAC design and drafting, MEP (mechanical, electrical and Plumbing). Psychometric means study of air properties. In literal sense of Air conditioning, air is the aspect to deal with. This air can be Supply air (SA), Return air (RA), Fresh air (FA) and Extract air(EA). SA and RA contribute to maintaining the temperature of the room as per the human comfort. FA and EA signify to the ventilation part. The outside air i.e. the ambient air varies from city to city and from variant time zone. The inside temperature or the desired temperature is universally considered to be between 21 deg C to 26 deg C; ideally 23 deg C. This indoor temp is universally accepted temperature range which is considered satisfactory for human comfort. Other factors which influence human comfort in HVAC system include the metabolic rate of the individuals, their physical activity, health conditions, clothing, food and drink etc. Generally speaking it is associated with individual metabolism rate which produces heat.

Psychometric analysis does not only signify to the temperature aspect but also to at Relative humidity ie RH and that means % of moisture content in air. For HVAC design and drafting, basically there are five major aspects:

• Dry Bulb Temp
• Wet Bulb Temp
• Dew Point Temp
• Relative Humidity
• Humidity Ratio

The preparation of psychometric table in HVAC design and drafting leads to the Heat Load Calculation which makes sure how much heat in unit of BTU/Hr needs to be dissipated and against that how much cooling in terms of TR needs to be entertained in the desired location. 

A Psychrometric Chart is very important tool for HVAC engineers which helps them to carry out heat load or cooling load calculations. This also helps HVAC design and drafting engineers find solutions to various air condition related problems. The psychrometric chart in overall shape looks like a shoe.

SMS Based home automation using Arduino Microcontroller

Today GSM networks are widely used, either for making calls or sending SMSes. Let us discuss a project of controlling home appliances by sending sms.

There are many types of home automation systems available in the market. Some are DTMF controlled home appliances, IR remote controlled home appliances and RF based. This system executes accurate control according to the message sent by the mobile phone. Just by sending a message to the GSM modem interfaced to a Arduino microcontroller (MCU) on/off operations can be performed. Present status of the equipment is also verified through a LCD display.

Arduino Microcontroller based home automation system works off 12v power supply. Arduino microcontroller (MCU) requires only 5v but GSM modem requires 12V. A LCD display is used for receiving and displaying the messages. Here LCD is used in 4-bit mode, which means only four lines are required to display data. When you want to control equipment and show its status information, you need to send an SMS to GSM Modem. Arduino Uno reads the messaged received by the GSM modem and sends commands to control the equipments and displays its status on LCD. GSM modem sends the commands in the text mode to Arduino Uno using RS232 interface.

AT command is sent from Arduino Uno to the GSM modem as the program starts up, and the response is received from the GSM modem after a very short period of time. After receiving the command to turn on loads, the relay set performs the switching operation.

The home automation market is growing very fast and there is a need a vast range of developments is carried out. Arduino Uno along with GSM provides smart automated home system with desired buad rate of 9600 bps.
