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.

What is the use of PLC in an industry and why its important?
Programmable Logic Controllers (PLCs) are crucial for various industries for several reasons: Automation: PLCs automate industrial processes by controlling machinery and equipment. This automation improves efficiency, reduces human error, and increases productivity. Industries ranging from manufacturing to energy rely on PLCs to automate tasks such as assembly lines, conveyor belts, and chemical processes. Flexibility: PLCs offer flexibility in programming, allowing for easy customization and reconfiguration of control logic to adapt to changing production needs. This flexibility enables industries to quickly adjust to new product specifications or process requirements without significant downtime. Reliability: PLCs are designed to operate in harsh industrial environments and are built to withstand extreme temperatures, humidity, vibration, and electrical noise. Their robustness ensures reliable operation even in challenging conditions, minimizing downtime and maintenance costs. Data Collection and Analysis: PLCs are often equipped with input/output modules to gather data from sensors and equipment. This data can be used for real-time monitoring of processes, predictive maintenance, quality control, and performance optimization. PLCs can also communicate with higher-level systems such as SCADA (Supervisory Control and Data Acquisition) or MES (Manufacturing Execution Systems) for comprehensive data analysis and reporting. Safety: PLCs play a crucial role in ensuring the safety of industrial operations. They can be programmed to implement safety interlocks, emergency shutdown procedures, and other safety protocols to protect personnel, equipment, and the environment from accidents and hazards. Scalability: PLCs support scalability, allowing for easy expansion or modification of control systems as production requirements evolve or new equipment is added. This scalability enables industries to efficiently grow their operations without the need for extensive reengineering or investment in new control infrastructure. Integration: PLCs can integrate with other automation technologies, such as robotics, motion control systems, and human-machine interfaces (HMIs), to create comprehensive control solutions. This integration streamlines operations, enhances coordination between different components of the production process, and improves overall system performance. Overall, PLCs are indispensable tools for modern industrial automation, providing the foundation for efficient, reliable, and flexible control of manufacturing and production processes across various industries.
