Impact on Industrial Automation with the advent of IoT

Connected Industrial Devices are known as IoT which means it is about a lot of industrial devices networked together. This technology enables us to manage everything from anywhere, reducing complexity and hardware cost, flexibility and easy expansion. More wireless modules will be added. In other words, IoT is the network of physical objects or things embedded with hardware of electronics, softwares which are connected in network either in wired or wireless mode to collect and exchange data.

The devices used in industrial automation which includes PLC, SCADA, HMI, DCS, Industrial networking, AutoCAD, Panel Design, Motors and Drives will be networked together in a better way with high levels of security and reliability.

The first impact of IoT technology is in the automation industry as they have no option left but to use the latest features and technology available in the market which increase the operational efficiency manifolds in today’s scenario.

Relevance of Profibus Communication for Industrial Automation Engineers


Every automation engineer whether from the background of electrical or electronics or instrumentation and control knows the importance of Profibus Communication. This technical note is primarily for freshers in the field of automation covering the whole spectrum of PLC, SCADA, HMI, DCS, Industrial networking, AutoCAD, Panel Design, Motors and Drives etc.

Profibus DP stands for “Process Field Bus Distributed Peripherals”. The main advantage of profibusdp connection is that we can connect master with slaves. Here master is our main controller and slave is our field device. This comes under the study of industrial networking.

In s7-300 (Rack type controller), one rack equal to 11 slots and at a time maximum of 4 slots are controlled by one controller. s7-200 and s7-300 works on half duplex protocols. Protocol is nothing but a set of rules for sending and receiving the data. Similarly, HMI also works on half duplex protocol which supports 32 nodes ( or devices). Maximum distance between master and slave can be 32 kms. The transmission rate of profibus connection is 9.6 KBps to 12 Mbps. Repeaters are used to boost the signal. We prefer serial transmission instead of parallel transmission in long distance connection because of lesser transmission loss and reduced cost.

The individual should be active and ready to work for hours on the industrial environments. Excellent communication skills and proper dressing code is also required for this job, individual have to maintain proper gesture and postures during working hours.
Depending upon the installed equipments in the plant, individual have to know the complete work flow of the system as well as complete understanding of the components implemented. There are different types of PLC's used in industries as per the requirement such as Allen Bradley, Modicon, Siemens, Mitsubishi, GE Fanuc, Omron, Toshiba etc. The Automation engineers have to deal with PLC's accordingly and has to control the process flow as per the norms.
Overall efficiency of the system is completely based on the automated systems implemented in the plant; an automation engineer is responsible for the complete process flow of the overall system therefore, he should posses' deep understanding and maintains quality of the products with higher efficiency using the installed system within given time constraints. An automation engineer works as the backbone of any automated industry and fulfill the gap between industry requirement and control flow of machinery.
Job Description of Building Automation Engineer: - Building automation engineers are responsible for all the integrated automated systems on a particular site. He is the one who have to supervise the installation and maintenance of complete automation systems. It includes CCTV surveillance systems, fire alarms systems, HVAC and Access control systems such as biometrics, smart cards, automated door locks etc.
Automation is required in every sector in today's developing world, need of automation for highly secure and controlled accessibility is required in day to day life. When the output required is highly accurate with negligible errors automated machinery have to be used, such as access controllers used in Metro's, Fire alarm systems used in highly sensible sites, CCTV surveillance systems in high security regions, and HVAC's for control rooms and integrated systems. Building automation engineer is the one who is responsible for designing, assembling, installing, testing and commissioning of the overall systems integrated in automated buildings.
