Programmable Logic Controllers (PLCs)

Programmable Logic Controllers (PLCs) are specialized computers used to control industrial and manufacturing processes. These robust devices take inputs from sensors, execute logic programmed by an engineer to make decisions, and send outputs to actuators to control machinery. PLCs have a modular design, usually consisting of a central processing unit (CPU), memory, input/output (I/O) modules for various signal types, power supply, and a communication interface. The CPU orchestrates the process by executing the control program stored in memory.

A primary advantage of PLCs is their flexibility and adaptability to a wide range of applications. They can be programmed in several languages, including Ladder Diagram (LD), Function Block Diagram (FBD), and Structured Text (ST), as per the IEC 61131-3 standard. These controllers are designed to withstand harsh industrial environments, often featuring durable enclosures that protect against dust, moisture, temperature extremes, and electromagnetic interference. The communication capabilities of PLCs allow them to interface with other equipment and networks, enabling integration with other systems for tasks such as data logging, monitoring, and remote control.

Since they are mission-critical components, PLCs emphasize reliability and easy diagnosis of issues. This often includes fault tolerance and diagnostic functions, and the ability to run software simulations for testing control logic before deployment.

Overall, PLCs are an essential element in modern automation, helping engineers achieve greater precision, efficiency, and reliability in complex control tasks. Airline proudly represents PLCs from brands such as Omron Automation, Phoenix Contact, Bosch Rexroth, Eaton and more.

Considerations for selecting a PLC:

  • How many inputs and outputs are required?
  • Does the PLC require the ability to control motion, vision, machine safety?
  • Does the PLC have to communicate with other intelligent devices on the machine/system?
