33.4.1 Procedure - Checking Logic Operations on the Computer

1. Open the project file you want to simulate and from the [Project (F)] menu, select [Simulation (L)].

   

   • You can also use the keyboard shortcut Ctrl+T to start simulation.

   • You can also click from the State bar to start simulation.

2. [GP-Pro EX Simulation] is displayed.
   

   

   • When you edit the project and run simulation again, close [GP-Pro EX Simulation]. Do the same when running simulation for a different project.
     After editing or opening a project that you want to run simulation on, update the contents in [GP-Pro EX Simulation] using one of the following.

   • From the [Project (F)] menu, select [Simulation (L)]

   • Press [Ctrl]+[T]

   • Press [F12]

3. Select [Preview (W)] and point to [Logic (L)] from the [View(V)] menu, or click .
   [Logic View] is displayed.
   

   

   • If [Address View] or [Logic View] is displayed over the [I/O View], click the [Logic] tab to bring the [I/O View] to the front.

4. From [Screen List], double-click the logic program you want to display.
   In the [Logic View], operational status of the logic program is shown with green lines.
   (For example, MAIN A Manufacturing System)
   

5. In order to switch the symbol variables ON/OFF, right-click to select [ON]/[OFF] or [Force ON]/[Force OFF].
   

   

   • When you specify [Force ON] or [Force OFF], the symbol variable keeps its ON or OFF state until you remove forces.

6. In order to change the current value of the symbol variables, right-click the value and select [Edit] or double-click on the value to change it. This updates the current value.
   

7. To stop the logic program, click (Stop) or select (Pause).

8. Select [Exit from Simulation (X)] from the [Simulation (S)] menu of [GP-Pro EX Simulation] or click to exit the simulation feature. [GP-Pro EX Simulation], [Address View], [I/O View], and [Logic View] will close.

   

   • The data that is saved in the backup memory (SRAM) during simulation is deleted after simulation ends. To save a backup of PLC device values, from the [Options (O)] menu select [Configure Memory (M)] or click . If you select the [Backup the PLC device] check box in the [Device Memory Settings] dialog box, the data of the same address can be read when the same file is re-opened.
