Terminology

The following terminology is used in the State Transition Tables:

• Current State - the current execution state of the step program. You can find out the current state by reading the attribute ExecutionState.

• Current Timer - the timer state of the current step before you change the execution state.

• Command - the command you write to the execution state command attribute (ExecutionStateCmd).

• Target State - the state of the step program execution after you have written the execution command to the attribute ExecutionStateCmd. This is your desired execution state.

• Target State Timer - after you write the execution command to the attribute ExecutionStateCmd, the timers act accordingly. They may restart, continue, or stop.

• Target Step - the step that becomes active after you write the execution command to the attribute ExecutionStateCmd.

• Execution OnExit - informs you whether Sequencer writes values to the OnExit outputs (if configured) of the currently active step after you write the execution command.

• Execution OnEntry - informs you whether Sequencer writes values to the OnEntry outputs of the step that is active after the currently active step.
