PLC stands for Programmable Logic Controller. It is a computer that controls/automates industrial machinery and equipment by monitoring inputs, and controlling outputs based on what the program running on the PLC tells it to do.
Examples of inputs: tachometers, switches, thermostats, etc.
Examples of outputs: lights, horns, high voltage contacts for switching motors on and off, etc.
PLC's are used to control amusement park rides, conveyor systems, and most industrial equipment found at production lines, mills, etc. A PLC can be used to control/automate virtually any piece of equipment or machine.

What does the flashing of the leds on a PLC controller mean?
The item for which the LED indicates is in a fault condition. Since there exist many brands of PLCs, there are many conditions indicated such as BUS FAULT, SYSTEM FAULT, I/O FAULT, COMMUNICATION FAULT, and many others.
What is profibus communicatio protocol?
Profibus is a field bus standard that contains a set of protocols (located in three levels of the OSI model) that make possible communication between PLCs and distributed I/O modules, HMIs, drives, et cetera. It was developed in the late 80s by several companies (including Siemens).
Where can one find information on programmable logic controllers?
One can easily find information on programmable logic controllers by searching on the internet, however, the some quick info can be found right here.Programmable logic controllers (PLCs), are digital computers that are made to perform logical computations to ensure smooth operations of mechanical devices.
Who is better a software engineer and a telecom engineer?
You can do anything you want. It depends on what course you want to take, and what field you are interested in. In the field of PLCs (Programmable Logic Controllers) you usually have to do both. Most people do choose one or the other, but if you just can't decide taking both might help you find which one you like more.

PLC Training is a Great Way to Develop a New Career?
Due to many changes in the economy, many people have been forced to consider new career options. One possibility you should consider is PLC training. PLC stands for programmable logic controller. The PLC is a kind of computer first designed during the 1960’s and 70’s to replace incredibly complicated electrical systems in automobiles that at one time had to use a few hundred thousand different relays. Out of this effort to find a simpler way for automobile electronic systems to operate came the PLC. PLCs, unlike the kind of computers we are most used to, were designed with electrical technicians in mind as opposed to regular computer programmers. Due to this design influence many PLCs implement a computer language referred to as “ladder logic.” Ladder logic programming language is similar to the schematic design of circuits. The logic was that ladder logic would be easily understood by technicians and engineers without much new training. Many PLCs today still implement ladder logic. However, new programming languages are now used in a number of PLCs. These include BASIC programming as well as “state logic.” State logic is a kind of programming language specifically designed for use in PLCs that implements state transition diagrams that use a series of “tasks,” “states,” and “statements” to tell electronic systems what to do. State logic is considered one of the most advanced programming languages that exist. Due to the use of these complex programming languages and the use of multiple inputs and outputs, PLCs are implemented as a way to control the very intricate timed electrical processes of the many different components in a machine. Uses of PLCs across different industries are wide and varied. They are of course used in the assembly of automobiles for which they were designed. A PLC has probably told the traffic light you have stopped at to change from red to green. You may have even encountered one that told the roller coaster car you were riding in to slow down. Due to the many uses of PLCs and the specified knowledge it takes to work on one, PLC training is a great option for developing a brand new career.
Four tasks in addition to relay switching that PLCs are capable of performing?
I. Timing II. Counting III. Calculating IV. Comparing
Why is your ex gorl keeping your plcs on Facebook?
She either doesn't know how to delete them. Isn't ready to let go. Or wants to know how to edit them so she can make you look uglier than you already are.
