function block Last modified: Friday, June 01, 2007

In software languages, a function block contains input variables, output variables, through variables, internal variables, and an internal behavior description of the function block. Function blocks are used primarily to specify the properties of a user function. Many software languages are based on function blocks. Function block is abbreviated as FB. See also function block adapter (FBA).

Consistency During the Design of FP Adapters (PDF) The focus of this paper lies in a consistent design of Function Block Adapters (FBAs). Function Block Programming (PDF) Function Block Diagrams (FBDs) are another part of the IEC 61131-3 standard. The primary concept behind a FBD is data flow. Function Blocks In engineering disciplines, especially within time driven systems, software languages are often based on function blocks. By Torsten Heverhagen, Robert Hirschfeld, Rudolf Tracht.
