If the switch is released, or if limit switch LS1 opens, The opening operation will continue as long as the

Pressing the Open Switch will cause the door to move upwards (open) if.

However, all other available InputsĪnd Outputs are employed in this exercise. Movement will not be maintained whenĮither switch is released, and therefore the Stop switch is neither

In this exercise the Open and Close pushbuttons will be used toĬontrol the movement of the door.

The program you create will monitor andĬontrol this equipment while adhering to the following criteria: Operator Control Panel, all connected to your PLC. The Door System includes a Reversible Motor, a pair of Limit Switches and a Of Relay Logic Instructions to design a program which will control the LogixPro Door Simulation. In this exercise we want you to apply your knowledge You understand the rational of the observed results. Don't continue on with the exercise until you are confident that Use your mouse to press the Stop switch on the Control Panel a few times, and You should also note that bit I:1/02 is also in a High or True You should now be able to see the current state of each bit associated When you have the Data Table showing, select the 'Input Table' from the drop down Now open the Data Table display byĬlicking on the Data Table icon located on the toolbar (3rd from right) at the top

The RUN mode which will initiate scanning. To confirm your assessment of the current limit switch states, place the PLC into With the door fully closed, what signal level would you expect to seeĪt the limit switch inputs I:1/03 and I:1/04? Run your mouse over each switch, and you should see a tool-tip textīox appear, which denotes that the selected switch is wired using a set of Normally Is in the closed position, both limit switches are in their activated state Take the time to familiarize yourself with the components used in the Door system,Īnd take particular note of the current state of the limit switches.

From the Simulations Menu at the top of the screen, Select the Door Simulation.
