the method used by the plc to write a ladder logic program is called

The essential components of PLC are Input/output (I/O) modules, co-processor modules, CPU, and peripheral devices. Hence, to overcome such drawbacks, PLC was created.Ī PLC model has a simple appearance. Relay also consumes plentiful electricity, more space, and heat.Relays also fail quickly compared to computer components.A change in the logic of the machine makes the process complicated. The machine operation using relays logic was quite challenging and time-consuming.The drawbacks of relays that make them unsuitable for the automotive industry are listed below: PLC was initially created in the United States for the replacement of relay systems. PLC ranges from small devices with few Input/Outputs to large devices with thousand of Input/Outputs. The applications include Robotics, water filling tanks, etc.

It monitors the state of input devices, takes decisions, and controls the output devices.

It provides easy, flexible, high-reliability programmable controllers suitable for simple and harsh environments. It involves a basic study of Microcontrollers, digital circuits, and designing skills. PLC is a digital computer control system adapted to control the robotic devices and other manufacturing processes. In this tutorial, we will cover the following topic: Here, we will discuss Automation, applications, types, programming, process, architecture, etc. Most organizations require a candidate having knowledge of PLC. PLC is one of the demanding skills of the Electrical industry. It is a special-purpose computer without a keyboard, hard drive, etc. PLC or Programmable Logic Controller is a computer control system for the Automation Industry.
