An Introduction to the Function Block Diagram (FBD) Language in TIA Portal

Industrial automation relies on various programming languages to implement control logic effectively. Among the five languages IEC 61131-3 standardized, the Function Block Diagram (FBD) is a prominent choice. This graphical programming language offers engineers a powerful tool for designing complex control sequences within the TIA Portal environment. FBD is renowned for its ability to harness predefined function blocks, encompassing mathematical operations, timers, counters, and logical functions. Operating within a visual canvas, these blocks interconnect via lines representing data flow, facilitating intricate automation systems' design, debugging, and maintenance.
