Function Blocks

Last updated May 16, 2025, generated by Sumble

What is Function Blocks?

Function Blocks are reusable software components that perform specific functions. They encapsulate algorithms and data, communicating with each other through defined input and output connections. Function blocks are commonly used in industrial automation and control systems to simplify the development and maintenance of complex logic by allowing systems to be built using pre-built and tested software modules.
