Internal Variables of Step

For every step, the structure built of two readable variables is declared by default. The first variable of BOOL type called state is a mark of step activity. It means Boolean step variable <StepName> in its simplified SFC implementation. The second variable of TIME type called currentTime declares step activity time. Step variables are available via step name and point the same way as function block structure or incident data — <StepName>.currentTime. Step variables can be used in transition conditions.
