User Defined Function Blocks are a way of making the logic in a PLC program re-usable.
The UDFB associates a set of inputs, outputs, and internal data with a logic sequence. Multiple instances of the UDFB can then be created and used throughout a program. Each instance of the UDFB will have its own set of data registers to work with.
By using multiple instances of the same logic sequence, it is possible to make a change throughout a project by changing a single logic sequence in one place. UDFBs can also be used across different projects.
