At a Glance

Animation of a section in Function Block Diagram language:

The background color of the editor is gray.

The colors used in offline mode for the various elements (instructions, variables, comments) are:

  • for Boolean variables:

    • green if the variable is TRUE (1),

    • red if the variable is FALSE (0).

  • yellow for numerical types of variable.

NOTE: Derived data (DDT) instances and function block (EFB\DFB) instances are animated in a display window and not in the language editor. You can view type, name, address and comment of a numerical variable (yellow) in a help bubble (Tool tip) when you position the mouse pointer over the variable.
NOTE: In an FBD section:

  • the unconnected parameters of elementary functions are not animated,

  • the unconnected parameters of function blocks are animated.

The result of textual expressions is also animated:

  • in green and red for Boolean expressions,

  • numerical expressions are replaced by their result, the associated help bubble (Tool tip) displays type, name, address and comment of the expression.

Animating the Links

There are 2 types of link:

  • Boolean links between function blocks,

  • numerical links between function blocks.

These 2 types of links are animated in the following way:

  • Boolean links between function blocks are shown in green or red depending on whether the output parameters to which they are connected are TRUE (1) or FALSE (0),

  • numerical links between the function blocks are shown in black. They display the value of the output parameter to which they are connected.
