Adding the PLC Ladder Logic 4.1 Setting up the layout of your circuit (Stop simulation) In order to add the Ladder Diagram on the same page, you need to make sure that the layout will leave you enough space to do so. 1) Zoom out (section 1.7) to see your entire page 2) Click and hold the left button of the mouse, and move cursor to select all components, then release the mouse button 3) Drag-and-drop the selected components to make space on the page 4.2 Adding PLC Input / Output Cards Navigate through the Electrical Control (JIC Standard) library to find and select the PLC Cards. Add the following components to your schematic: PLC Input Card PLC Output Card Make sure to place the Input Card on the left and the Output Card on the right as shown in the image. Note: the same logic circuit can be build using the IEC Standard. 4.3 Connecting electrical components to the Input card From the main Electrical Control (JIC Standard) library reproduce the schematic on the right, by adding the following components to your schematic: Common (0 Volt) Power Supply 24 Volts Normally Open Push-Button* *When inserting an Electrical Control component on the schematic, the software will ask you to give it an Alias, this will be the tag displayed on your schematic and will be used for linking components. Name the Normally Open Push-Button PB Connecting the electrical component to the Output card From the main Electrical Control (JIC Standard) library reproduce the schematic on the right, by adding the following components to your schematic: Common (0 Volt) Power Supply 24 Volts Solenoid, DC/AC* *Name the Solenoid A+. 4 of 9

5 Your schematic should look like this at this point 4.5 Inserting the rung Now that we have connected the Electrical control components, we can focus on the Ladder diagram which contain the logic in that circuit. From the main Ladder for AB PLC library (Allen Bradley ), drag-and-drop the Rung on the schematic and place it between the two PLC cards. Your Rung may be too big, too small or overlap on your cards, simply click on the green square to resize it between the two cards 4.6 Creating the Logic Drag-and-drop the following components from the main Ladder for AB PLC library (Allen Bradley ) to create the logic circuit: Examine if Closed Output Energize (OTE) When inserting a Ladder Logic AB PLC component on the schematic, the software will ask you to give it an Alias, this will be the tag displayed on your schematic and will be used for linking components. 4.7 Linking PLC components Link the Normally Open Contact ( ( ) to the PLC cards. ) and the Output The Normally Open Contact has a? beside it, this means that it is not linked to any Electrical circuit. Double-click on the Normally Open Contact to open the linking window. 1) Click on Variable Assignment from the left-side menu 2) Use the filter from the Compatible Simulation Variables, filter on the Alias IN of the Input Card 3) Once you have identified your Alias, double-click on it to create the link 4) In this section, the? will be replace by E1.IN0 ( E1, name of the card. IN0, input 0) confirming that the link is created 5) This line shows the association between the two components 6) Close the window by clicking on the X *Repeat these steps to link the Output ( OUT0 (output card) ) to the 5 of 9

6 4.8 Linking the Pneumatic Solenoid Link the Electrical Solenoid? (ls) of the Directional Valve with the Electrical Solenoid A+ of the Output card. The Solenoid of the Pneumatic Directional Valve has a? (ls) beside it, this means it is not linked to any Electrical circuit. Double-click on the Directional Valve to open the linking window. 1) Click on Variable Assignment from the left-side menu 2) Click on the solenoid icon of the directional valve 3) Use the filter from the Compatible Simulation Variables section to sort the variables and only show the one matching your criteria, filter on A+ 4) Once you have identified your Alias, double-click on it to make the link 5) In this section the? (ls) will be replace by A+ confirming that the link is created 6) This section shows the association between the two components 7) Close the window by clicking on the X" 5. Simulation 5.1 Start simulation (section 3.1) Now that all the components are connected and all the links are created, you can start the simulation to see your circuit come to life and the interaction between the different technologies. While in simulation, click on PB1 to energize INO which will close the open contact E1.INO and which will activate the OUT0 to energize A+ on the Output Card and on the directional valve which makes the cylinder extend. Each time you release the PB1 button the cylinder retracts because of the spring on the directional valve. Let s change the schematic so one push on PB1 makes the cylinder extend completely. 6 of 9

7 6. Adding a Latching Contact 6.1 Changing the circuit (Stop simulation) Move the relay OUT0 down, as shown, by disconnecting the component using the Shift key (section 1.8). This will leave room to add an internal bit on the first rung. 6.2 Adding a Latching contact and an Internal bit Drag-and-drop the following components from the main Ladder for AB PLC library (Allen Bradley ) to create the circuit on the right: 2 x Examine if Closed Contact Output Energize (internal bit) *Name the Output Energize B3: Connecting the components Connect the added components to reproduce the circuit shown on the image. 6.4 Linking the Latching contact and simulating the circuit Link the two normally open contacts ( ) to the Internal bit relay B3:0 (Section 4.8). Once these links are made you can launch the Simulation (section 3.1). By clicking on PB1, the cylinder extends fully but doesn t retract since there is no element to de-energize the OUT0 which is now latched. Let s add a Timer to make the cylinder retract after 5 seconds. 7 of 9

8 7. Adding an On-Delay Timer 7.1 Adding On-Delay Timer (Stop simulation) Navigate through the Ladder for AB PLC library (Allen Bradley ) select the Timers category. Drag-and-drop the following on your schematic to create the circuit on the right: Timer On-Delay (TON) Examine if Closed contact 7.2 Connecting the ON-Delay Timer Connect your On-Delay Timer as well as your Examine if Close contact. Link the Examine if Closed contact to the Internal Bit B3:0 (Section 4.8). 7.3 Adding a Timer Done Bit DN Once the On-Delay Timer is in place and connected, add the Timer Done Bit DN Contact in the circuit to de-energize B3:0 once the Preset time on the Timer is reached. NOTE: When dragging a component from the library, if you drop it directly on a line, it will automatically insert that component into the circuit. This will not work however if you drop the component on your working space before. Drag-and-drop an Examine if Open ( ) from the Ladder for AB PLC library (Allen Bradley ) directly on the first line between E1.IN0 and B3:0. Make sure the connection ports are black, which indicates that the connection is well made. If they are red, it was not inserted correctly, repeat the step above. 8 of 9

9 7.4 Link the Examine if Open Contact Link the Examine if Open Contact to the Timer Done Bit of your Timer DN (Section 4.8). Search for DN in the filter section. Your circuit should look like the image on the right 7.5 Adjusting the Timer On-Delay By default, the Timer has a Preset time of 10 seconds. Change its value to 5 seconds. To do so, double-click on the Timer On-Delay to open the Properties window. 1) Click on Data from the left-side menu 2) When the Star is filled orange ( ), it means that only the favorite fields are displayed. Click on the Star to display all the fields, and find the PRE field 3) Change the value of this field to 5 seconds 4) Exit the window by clicking on the x top right corner. 7.6 Simulating your circuit Now that your circuit is completed, launch the simulation and see your entire circuit come to life! Click on PB1, the cylinder will extend and the Timer On-Delay will be activated. Once it reaches the 5 seconds Preset time, the DN contact will open de-energizing B3:0, the cylinder will retract since OUT0 will no longer be activated.
