Transcribed Image Text:The main difference between a selection sequence and a simultaneous sequence is
Selection sequence
Simultaneous sequence
+
+
O a. None of the choices
O b. The selection sequence allows to repeat one of the steps continuously in a loop
O c. The selection sequence allows to select between the current step and one of the two next steps
O d. Whenever one of the transition conditions of a simultaneous sequence is active, it runs the closest next step and then the second
next step
O e.
The simultaneous sequence runs both next steps whenever the transition condition is active, while the selection sequence has two
transition conditions and runs one of the next sequences
