As one of the official PLC programming languages described in IEC 61131-3, FBD is fundamental for all PLC programmers. It is a great way to implement everything from logic to timers, PID controllers, and even a SCADA system in your solution, etc. Most engineers love FBD because it is graphically a very common way to describe a system.

Variations in symbol dimensions PLCopen and therefore the IEC 61131-3 standard doesn’t give precise symbols for ladder diagram PLC programming.
Some slight variations occur between the symbols when used in semi-graphic form and when in full graphic.

Each symbols represents instruction which you need while building ladder logic. All the ladder logic symbols or PLC programming instruction available in the format of bit logic, arithmetic, logical, counters and timers etc.
IEC-61131-3 är en standard för programspråk för programmerbara styrsystem (PLC), som är något av en kompromiss mellan olika tillverkares egna programspråk. Den definierar 5 programspråk för programmering av PLC:n: Sequential Function Charts (SFC) Ladder Diagram (LD) Instruction List (IL) Function Block Diagram (FBD) Structured Text (ST)
