Function Block Diagram (FBD) Algorithms

In versions of the FBDK after 2006-09-01, the functional programming paradigm has been adopted for efficient runtime execution and easier formal validation of algorithms in the IEC 61131-3 FBD language:

Functions

Connections

Parameters

Parameters (constant inputs) of functions in FBD algorithms can be edited in the same manner as for function blocks, resources, etc. However, since these are active inputs to functions, the display of parameters cannot be turned off by the popup menu's Parameters item for FBD algorithms.
