State matrix rows
Previous Topic  Next Topic 

State matrix rows (or  cols, in fact the dimension that is not the lookup source) can be referenced by special SFC Phase/Op Step symbols. For example a step might set an equipment module or unit to a state defined in a matrix row.

When a matrix row name is changed ControlDraw checks if there is a Set State SFC Step that is affected (based on the text and the page - matrix links, set in the diagram details) and after prompting changes the step text.

The 'Set States' Tab shows all the Set State steps that are associated with the current matrix. They are coloured Green if the State exists, Yellow if it does not or Grey if there is no Set State statement in the step text.
