Function Block Diagram is easy to learn and provides a lot of possibilities. As one of the official PLC programming … See more In the standard from IEC, a lot of function blocks are described. Here’s an overview of the most important blocks in the official FBD description. The most basic functionality of a PLC program is logic. Combined called … See more I like to think of the next type of function blocks as asking questions. Is A equal to B? Is CV greater than PV? It is time to compare some numbers! Comparing is actually something … See more All these function blocks above are most of the ones described in the IEC 61131-3, the official standard for PLC programming languages. There are many more function blocks provided in the function block diagram. Actually … See more Comparing two or more values is useful. But sometimes, instead of comparing, you will have to choose between values. The selection function blocks give you that opportunity. What they all have in common is that they give you … See more WebA signal-flow graph or signal-flowgraph (SFG), invented by Claude Shannon, but often called a Mason graph after Samuel Jefferson Mason who coined the term, is a specialized flow graph, a directed graph in which nodes represent system variables, and branches (edges, arcs, or arrows) represent functional connections between pairs of nodes. Thus, …
