Refer to the Help or the Operation Manual of the PDF file for detailed descriptions. - Acrobat Reader 5. 0 or later is required to read the PDF files. [. . . ] Right-click the Gate Fully Closed Flag transition, and select Connections - Draw Connection From Transition as Jump from the pop-up menu. A jump is functionally identical to a loop. The SFC chart is now completed, except for the actions. 2-23 2-6 Compiling 2-6 Compiling Test the program before creating actions for the steps. 2-6-1 Checking for Program Errors Compile the program to check for errors. 1 Check all programs. Press the F7 key. Compilation results will be displayed in the output window. If no error is detected, the program will operate properly. If an error is detected, correct the problem in SFC editor. 2 Creating Programs with SFC 2-6-2 Saving Projects Save the created program. 1 Name and save the project. Select File - Save As. The Save CX-Programmer File dialog box will be displayed. Enter a file name, and click Save. 2-24 2-7 Simulated Transition Test 2-7 Simulated Transition Test Before creating the actions, check how the program operates when the transition conditions are satisfied. The simulator will allow you to test programs using only the computer. 2-7-1 Online Connection to Simulator Transfer the program to the simulator. 1 Establish an online connection. Select Simulation - Work Online Simulator. An online connection will be established between the computer and the simulator. The Download Options dialog box will be displayed. 2 Creating Programs with SFC Click OK. The Download dialog box will be displayed. When the data transfer is completed, the Download successful message will be displayed. 2-25 2-7 Simulated Transition Test Click OK. Online connection is now completed. 2 Creating Programs with SFC 2-7-2 Setting Transition Conditions Confirm that the transitions actually take place when the transition conditions are satisfied. 1 Switch to Monitor mode. Select PLC - Operating Mode - Monitor. A confirmation dialog box will be displayed. Click Yes. The operating mode for the PLC will be switched to Monitor mode. The green frame represents the active step. Click the Vehicle Detection Flag transition. The Vehicle Detected program will be displayed in the program view. 2-26 2-7 Simulated Transition Test 2 Turn the input contact ON. Right-click Vehicle Sensor, and select Set On from the pop-up menu. The contact can also be set to ON/OFF by double-clicking the contact, just as with any standard ladder program. 2 Creating Programs with SFC When the Vehicle Sensor turns ON, the Vehicle Detected program outputs ON, and the value for the Vehicle Detection Flag transition becomes TRUE. Active status will be transferred from the Initial Step to the Issue Ticket step. Set or reset the other transition programs and confirm that the transitions take place. 3 End the simulation. Select Simulation - Work Online Simulator. The simulator will close. 2-27 2-8 Creating Action Blocks 2-8 Creating Action Blocks Create the processes for the steps as action blocks. 2-8-1 Creating Actions Create the actions using ladder. 1 Register an action program. The Initial Step does not require an action block, since there is nothing there to process. Create a ladder action program for the Issue Ticket step. Right-click the Issue Ticket step, and select Add Action - New Ladder Action from the pop-up menu. 2 Creating Programs with SFC An action block will be added. Right-click Action1, which has been added to the project workspace, and select Rename from the pop-up menu. 2-28 2-8 Creating Action Blocks Type "Ticket Issuance". The action program will be renamed to Ticket Issuance. The action will also be renamed automatically on the SFC chart. 2 Creating Programs with SFC 2 Create the program. In the Issue Ticket step, issue a ticket and display the "Take ticket" message. Create a program that starts these two processes when the step becomes active.
