What isModular 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.
