One of the most powerful capabilities of programmable logic controllers (PLCs) that conform to the IEC 61131-3 standard is the functionality that allows application engineers to create function blocks ...
According to the IEC 61131-3 standard, there is a difference between a function and a function block in PLC programming. The main difference involves internal memory. So for instance, a function can ...
The use of function blocks is one of the most important concepts formalised by the IEC 1131-3 standard. Using function blocks in the design of control software has many benefits including improving ...
As discussed in chapters 1 and 2, a fundamental property of IEC 61499 function block networks is that the execution of all software within every function block is, in some way, event triggered. In ...
