Difference Between Modular Type PLC & Standalone Integrated-Type PLC

What is Modular Type PLC?

A modular type PLC is a programmable logic controller system comprised of independent modules that perform specific functions such as processing, input/output, communication, (or) specialized functions. Users can configure and arrange these modules to match their own application requirements, providing for greater flexibility, scalability, & easier maintenance & extension.

Where are Modular PLCs used?

Modular PLCs are commonly used in applications requiring several inputs and outputs, which includes process control in manufacturing facilities. Rack-mounted PLCs are commonly employed in complicated applications requiring several inputs and outputs, which includes large process control systems in manufacturing facilities.

What is Standalone Integrated-Type PLC?

A standalone integrated-type PLC is a small unit with all components enclosed in a single enclosure. It is pre-configured with fixed inputs, outputs, & processing capabilities, which makes it ideal for simple applications where flexibility isn’t required.

Modular Type PLC vs Standalone Integrated-Type PLC

Modular Type PLC Standalone Integrated-Type PLC
A modular type PLC is made up of individual modules that are able to adjusted and configured to meet the application’s specific requirements. A standalone integrated-type PLC contains all components in a single unit or enclosure.
These modules usually consist of a CPU module, input modules, output modules, communication modules, & sometimes special function modules. These PLCs come pre-configured with specific inputs, outputs, & processing capabilities.
The PLC system’s modularity enables scalability, ease of maintenance, and development. They are usually less adaptable than modular PLCs as the hardware configuration won’t be easily changed or increased.
Users can select different types and amounts of modules in accordance with their requirements, making it more adaptable for a variety of applications. They are typically easier to install & require less initial configuration than modular PLCs.
It is appropriate for applications where customization, scalability, & flexibility are major considerations. Standalone integrated PLCs are frequently employed in simpler applications with well-defined requirements that are unlikely to alter.

What is an Integrated PLC?

An integrated Programmable Logic Controller (PLC) implements control algorithms through machine functions using information from the NC portion obtained from the NC-PLC interface and machine on/off inputs.
