Application of PLCs in process and manufacturing industries
PLC SCADA systems are used for automating process and manufacturing /assembly lines. Process means step-by-step procedure sequence, whereby a particular product is manufactured and assembled. Product engineering department is responsible for manufacturing plan of new or modified products. Some other PLC SCADA systems may be controlling sequences/ processes, which might involve filling/ capping/labeling/packaging of bottles, the printing of newspapers, or the automobile assembly lines etc. In many such manufacturing situations, PLC SCADA play very important role in carrying out the process.
Advantages of PLC systems
Number System in PLC
PLC is just like a computer, it therefore stores information in the form of On or Off conditions referred to as binary digits (bits).
Difference between PLC systems and PCs
PCs are generally data processing computers. Such computer systems process and analyze a large data, store this database, generate report and display the data/information to operators.
PLC system is generally a process control computer; small, manufactured to work in harsh environment and it is also easy to program, maintain and repair. PLC System can handle real time data and input output tasks whereas computers can handle non-real time tasks. PLC systems are generally installed near to the machine or process they control, and are generally considered as an extension part of a industrial equipment.

Advantages of PLC systems
- PLC systems have highest Reliability in operation
- Control systems have flexibility in modifying PLC logics
- Flexibility in PLC programming and reprogramming
- large contacts in small package
- PLC systems are very cost effective for complex control systems
- Small size but speedy operation
- PLC systems can communicate with other control systems & computer systems in the plant.
- PLC controlled systems have ease of maintenance troubleshooting
- Proper documentation & high level of Security
