Tip It is recommended that you view the Readme file for important related information on this product. In terms of maintenance, an electrician must be well trained and skillful in troubleshooting the control system.
In short, conventional relay control panel are very inflexible. Modification can be quite difficult.
Troubleshooting can be quite troublesome as you may require a skillful person. Machine downtime is usually long when problems occur, as it takes a longer time to troubleshoot the control panel. It causes longer downtime in maintenance and modification.
There are many advantages in using the programmable controllers.
The power consumption is greatly reduced as PLC consume much less power. In the first programmable logic controller came along to replace complicated relay circuitry in industrial plants. The PLC was designed to be easily programmable by plant engineers and technicians that were already familiar with relay logic and control schematics. Since the beginning PLCs have been programmable using ladder logic which was designed to mimic control circuit schematics.
The ladder diagrams look like control circuits where power is flowing from left to right through closed contacts to energize a relay coil. Ladder Logic Example As you can see, ladder logic looks like simple control circuit schematics where input sources like switches, push-buttons, proximity sensors, etc are shown on the left and output sources are shown on the right.
The ability to program complicated automated processes with an intuitive interface like ladder logic made the transition from relay logic to PLCs much simpler for many in the industry. Although, the first PLCs were very limited in their memory and speed capabilities, they quickly improved over the years.
The presence of PLCs helped simplify the design and implementation of industrial automation.
PLCs can be described as small industrial computers with modular components designed to automate control processes. PLCs are the controllers behind almost all modern industrial automation. But, we can describe the function of a PLC in simple terms. We will get into more detail later but for now, think of it like this: The CPU monitors the status of the inputs ex.
