Result of the simulation
The graph shows the signals relating to the simulation, in this case:
• when 2000 ms have elapsed the “Safety area" signal rises to logic level 1,
which indicates closing of the gate.
• when 3000 ms have elapsed the “Start_Press" signal rises to logic level 1,
which indicates the request to start sent by the operator
• The AND operator output signal “Op6” rises to logic level 1 when 3000 ms
have elapsed, i.e., when the two “Safety area” and “Start_Press” inputs rise to
logic level 1.
• The AND operator output signal is delayed by 2000 ms by the delay operator.
• The "Op7" retarder output signal sends the command to close the relay when
5000 ms have elapsed, at which time the "M-press" relay is activated.
