Text description of the model: systems with their blocks, parameters and signal connections, Stateflow data, states and transitions. The rest of the page is the interactive viewer with images, styles and scripts and holds no further model information.

Notation: "A:1 -> B:2, C:1" connects output port 1 of block A to input port 2 of block B and input port 1 of block C, a quoted text is the signal name. Block parameters show the values that differ from the block defaults, plus the main parameters. Transitions read "source -> destination: label" with the label event[condition]{condition action}/{transition action}; [n] is the evaluation order of transitions leaving the same source, the transitions of a state are tested before those of its active substates. States are exclusive (OR) unless a parallel (AND) decomposition is stated. Junctions are numbered J1, J2, ... per chart. "(in X)" names the state or function containing an object, objects without it are at the top level of the chart. Chart inputs and outputs carry their port number, "input 2" is input port 2 of the chart block.
