User interface and system for creating function block diagrams

A controller configuration system for creating and editing a function block diagram, comprising:

• a user interface allowing a user to create and edit a function block diagram, the user interface comprising:
• a function block diagram representation;
• one of a wire connector cross-reference indicia, a pin datatype indicia, and a block execution status information indicia;
• and
• a wired block parameter indicia that comprises an indication in a properties page associated with a function block that a parameter associated with the block is wired to a value source in the function block diagram representation, the indication provides that a value for the parameter may not be set manually in the user interface.

A user interface for creation and editing of a function block diagram in a controller configuration system, comprising:

• an input wire connector having an input wire name associated therewith;
• an output wire connector having an output wire name associated therewith;
• and
• a wire connector cross-reference indicia that provides an indication proximate at least one of the input wire connector and the output wire connector, and a hyperlink to a connection associated with the at least one of the input wire connector and the output wire connector;
• wherein the user interface is adapted to establish an association between a first function block diagram element connected to the input wire connector and a second function block diagram element connected to the output wire connector if the input wire name and the output wire name are the same.
