State Diagrams 6, Actions
Figure 6 introduces several new concepts:
- Several states can be combined to form a complete state diagram (I am sure you saw that one coming!)
- Events can be something more than an input turning on or off. In this case it is a temperature measurement being compared with some limit values.
- Actions, represented by rectangular boxes.
- A clearly defined place where the state machine starts, denoted in this case as "Init" (initialize).
There are two action boxes in this state diagram. One turns a heater off and one turns it on. The turn-off uses the same bar across the top of the word as I used for an input being off.
