Computers, often personal computers, can be used in automation as a machine for process control, connected to sensors and actuators through specific expansion cards.
Industrial PCs are designed to withstand harsh environment changes, such as temperature, dust, humidity, vibration, and power surges, and are equipped with high-quality electronic components and a special cooling system.

Microcontrollers

Microcontrollers are single-chip computers, equipped with a microprocessor, memory, and input/output, and are often programmed with high-level languages like C.
They require very few electronic components to interface with the outside world, except when controlling devices powered at 220 volts or higher.
Microcontrollers have replaced costly industrial PCs with simpler and cheaper cards in automation process control.

Embedded Systems

Embedded systems are preferred in workplaces where human interaction is non-existent or infrequent, as they do not require a monitor, mouse, and keyboard.
The program is loaded onto the card, and the system is included in the program to be controlled.
The majority of embedded systems are based on microcontrollers, and their programming is achieved by using a personal computer.

Programming and Maintenance

Embedded system programs are developed on a personal computer and then loaded onto the card through a serial, USB, or local network link.
Updates and maintenance are carried out by connecting the card to a personal computer via a communication port and transferring the updates developed on the PC card.

Programmable Logic Controllers (PLCs)

PLCs are employed in industrial processes to manage greater power and execute a program processing analogue and digital signals from transducers and generating them to actuators.
PLCs are specifically designed for industrial applications and contain power electronic devices to drive devices supplied with 220 volts or higher.
