Why is flexibility a key benefit of using modular PLCs?

Flexibility is a key benefit of using modular PLCs because they are designed to adapt easily to varying application needs. Modular PLCs consist of interchangeable components that can be added or removed according to the specific requirements of a task or project. This means that if an application evolves or expands, the system can be modified without the need for a complete overhaul, allowing for greater customization and efficiency.

For example, in a manufacturing environment, if additional sensors or control elements are needed to handle increased production, modular PLCs can accommodate these changes seamlessly by adding new modules. This adaptability not only helps in managing costs but also ensures that the systems remain relevant and effective over time, which is crucial in industries that face rapidly changing technologies and requirements.
