HOW TO READ FUNCTIONAL LOGIC DIAGRAMS
Function block diagram - Wikipedia
Function Block Diagram is one of five languages for logic or control configuration supported by standard IEC 61131-3 for a control system such as a Programmable Logic Controller (PLC) or a Distributed Control System (DCS). The other supported languages are ladder logic, sequential function chart, structured text, and instruction list. See also

OverviewHistoryDevelopment of functional flow block diagramsBuilding blocksA functional flow block diagram is a multi-tier, time-sequenced, step-by-step flow diagram of a system’s functional flow. The term "functional" in this context is different from its use in functional programming or in mathematics, where pairing "functional" with "flow" would be ambiguous. Here, "functional flow" pertains to the sequencing of operations, with "flow" arrows expressing dependence on the success of prior operations. FFBDs may also express input and output data dependencies..See more on enpedia · Text under CC-BY-SA license

Standard Function BlocksComparison Function BlocksSelection Function BlocksMake Your Own Function BlocksIn 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 most basic functionality of a PLC program is logic. Combined called combinatorial logic. Logic is the simplest form of algorithm that, via the states of its inputs can set some outputs. Basically, there are two different bit logic functions or operations in FBD. With just these two you can derive a wSee more on plcacademy

The use of logic symbology results in a diagram that allows the user to determine the operation of a given component or system as the various input signals change. To read and interpret logic diagrams, the reader must understand what each of the specialized symbols represent. This chapter discusses the common symbols used on logic diagrams.
Reading Logic Diagrams - tpub
Reading a logic diagram that does not provide information on the status of the gates is not any more difficult. It simply requires the reader to choose the initial conditions, determine the response of the circuits, and modify the inputs as needed. The following exercises will

How to Use a Breadboard - Now that you know how to read schematics, why not make one! Breadboards are a great way to make temporary, functional, prototype circuits. Working with Wire - Or, skip the breadboard and jump straight into wiring stuff up. Knowing how to cut, strip, and connect wire is an important electronics skill.

PDF fileA. Control Logic Diagrams have two basic purposes, functional operation and logic design. B. The functional operation of system equipment controls should be presented within Control Logic Diagrams so that it can be easily understood. The value of Functional Operation Diagrams is lost if the basic operation is obscured by excessive detail. 1.
