• Primetals Technologies India Pvt. Ltd, a J.V of Siemens VAI & Mitsubishi Industries.
• Area of expertise: Iron & Steel Making, Processing lines, Coal & raw material handling plants.
Introduction to PLC • Programmable Logic
Controllers (PLCs) are used in commercial and industrial applications.
• PLCs consist of input modules or points, a Central Processing Unit (CPU), and output modules or points.

Operation of PLC• An input accepts a variety of
digital or analog signals from various field devices converts them into a logic signal that can be used by the CPU.
• The CPU makes decisions and executes them.
• Output modules converts control instructions from the CPU into a digital/analog signal that can be used to control various field devices.

HMI Development• HMI(Human Machine Interface) is the interface module
which the operator has to face.• This screen provides a total, complete, comprehensive layout
of a particular process in a plant.• The entire process can be controlled , monitored via the
HMI.• Inner workings and programs can also be accessed and edited
by necessary means.• Used WINCC(Company provided software ) for this purpose.• All developments based on S7-400 PLC.
