Within a short space of time, automation practices have become an integral part of the overall process of many industries, particularly, the instrumentation and electrical industry. The importance of PLC in automation is becoming more and more apparent, and necessary.
What is PLC?
A PLC, or a Programmable Logic Controller is a logic controlling device which helps in controlling several functions in an industrial system. The primary function of this device is to continuously be in touch with the input devices and to make important decisions based on the custom program with respect to the condition of input devices.
A microprocessor is present in the PLC which holds the program written in computer language. This program is further transferred to the device using a cable. The program is stored in the non-volatile memory of a PLC. For user convenience, a visual programming language named Ladder programming was created to program the PLC. The main advantage of PLC is its capacity to change and replicate particular operations while gathering or sending important information. Another advantage of a PLC is its flexibility. The user has the option to choose between various input and output devices which best fits their needs.
What is SCADA?
Supervisory Control and Data Acquisition Control, or SCADA, helps to monitor all industrial processes from a central location. The location can be either local or remote. These devices can directly interact with many other systems with the help of the Human Machine Interface (HMI) software. It is also a type of auditory device since it logs everything into the system. The complexity of the SCADA system is relative to its purpose, which is its greatest advantage. It can control an incredibly complex or an easy system, depending on user needs.
PLC and SCADA in the Instrumentation and Electrical Industries
PLC and SCADA are used extensively in oil and gas facilities, mineral processing, chemical, factory automation, brewing, water and sewage treatment plants, they are used for flexibility, modularity and reliability. There are specific features of PLC’s that make them the preferred choice for industries that rely on these systems, such as:
- Easy to program
- Unified programming environment
- They collect robust data
- They can be used for predictive maintenance
Currently, there is a short supply of technicians and engineers with skills and competency in selection, installation, fault finding, commission and maintaining PLC’s. PMV uses, and trains students in Allan Bradley Micrologix 1000 controllers and RSlogix Micro-starter lite software, Siemens S7 200, 300 and 1200 (TIA complaint) hardware and Siemens KT600 Human Machine Interface with WinCC SCADA software, Rockwell Automation MicroLogix 500 and 5000 and Wonderware Intouch SCADA software.
