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 whole bunch of other logic functions let’s s..See more on plcacademy Function Blocks in Programmable Logic controllers Tutorial Function Blocks Programmable Logic controllers. Figure shows an example of a function block diagram. Function blocks can have standard functions, such as those of the logic gates, counters, or timers, or have functions defined by the user, such as a block to obtain an average value of inputs.
