Chart

Description

Block Chart — this is a graphical representation of a finite automaton. A finite automaton is a mathematical model of a device that describes a system with a finite number of states.

To get started with the block Chart put it on the Engee workspace and double-click into it.

Inside Chart the block library changes its appearance:

stateflow library en

Read about the states, nodes, transitions and memory nodes in the article State Machines.

Block Interface Chart It is unified with the interface for working with subsystems, so to exit it back to the workspace Engee use the hierarchy navigation tab sf hierarchy 2 on the model panel or press Esc:

sf hierarchy 1 1

Ports

Input

Port_in — input signal that creates the input port
scalar

The input signal is in the form of an internal block variable Chart, corresponding to the input port of the block. Appears after the creation of the input internal variable menu for adding signals in the settings window of the finite automaton model :

stateflow settings 3 1 1

The input port cannot be assigned an initial value.

Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, Int128, UInt8, UInt16, UInt32, UInt64, UInt128, Fixed

Output

Port_out — the output signal that creates the output port
scalar

The output signal is in the form of an internal block variable Chart, corresponding to the output port of the block. Appears after creating the output internal variable in the menu for adding signals in the settings window of the state machine model :

sf 1 2 3

Data types: Float16, Float32, Float64, Int8, Int16, Int32, Int64, Int128, UInt8, UInt16, UInt32, UInt64, UInt128, Fixed

Block Chart is a separate part of Engee, so variables from workspace is not available in it.

To make them visible, open settings window block Chart and add a signal by selecting the Parameter:

ka variable add

The name of the parameter must match the name of the variable in the workspace. You can view active variables in variable window variables article 2 1 .

If the block Chart located inside the masked subsystem, then the mask parameters can also be passed inside it. Read more about the creation of such subsystems in the article Masks in Engee.
