How does it work?

Mitsubishi PLCs are designed to execute a pre-programmed set of instructions to accomplish specific duties. These instructions are stored in the PLC’s memory, which is typically a non-volatile form of memory that retains the instructions even when the power is off.

The PLC’s input module collects data from various sensors and switches, which is then processed by the PLC’s CPU, which implements the corresponding output signals via the output module. The output signals are used to control motors, pumps, valves, and other equipment, among other industrial processes.

Typically, ladder logic or function block diagram is the programming language used to program a Mitsubishi PLC. (FBD). These programming languages employ graphical representations of logic functions to generate executable programs. Using specialized software tools, the programming language is then input into the PLC, and the program is downloaded into the PLC’s memory.

Once the program is operating, the PLC continuously monitors the input signals and controls the output signals according to the program’s instructions. Programming of the PLC is readily updatable or modifiable, allowing changes to be made to the industrial process without having to physically rewire the control system.

Mitsubishi PLCs control a variety of industrial processes by collecting data from sensors and switches, processing that data using pre-programmed instructions, and implementing the corresponding output signals. Consequently, they are an effective and efficient solution for industrial automation and control.
