Chapter 5 - Simulator Mode
As you saw from creating the sample project in the last chapter, downloading any changes you make to the OIT can
take time. To decrease the amount of time required to download a project to the OIT , uncheck the Firmware option
on EasyBuilder's download dialog.
A better way of testing changes made to a project is to use the computer to simulate the operation of the OIT.
This chapter shows you how to dramatically save time when creating and testing a project by putting the computer
into Simulation Mode. In Simulation Mode, the computer displays a screen that simulates what is seen when the
OIT executes the project file. You can use the mouse on your computer to simulate the operation of the touchscreen
on the OIT. Rather than waiting for the download to test each change you make to your project, you can now
instantly switch to Simulation Mode to see if your project is working as expected.
You can enter Simulation Mode in three ways. Using the sample project that you created in the last chapter, we will
guide you through the three methods.
The Sim u la tion Screen
All modes of simulation use the same screen.
For our example, we are showing the sample project as it would appear after the ON function key has been pressed.
When the Simulation Mode screen first appears, it will always show the startup screen of the project. You can test
any objects you have created which require touchscreen input by clicking on them. In this example, clicking on the
increment key simulates the key as it is pressed on the touchscreen. Simulation Mode always uses the compiled
version of the project that you have created (the *.xob file). Therefore, you must save and compile any changes you
make to the project before you can simulate it.
Simulating the OIT is done in on-line or off-line mode.
On-line simulation is most useful when a project is near completion and you need to test the interaction of the
project with the PLC. It is also very convenient when making minor changes to a project because these changes can
be instantly checked for operation.
Off-line simulation does not require any connection to the OIT. Because of this, off-line simulation is most often
used when starting a project. You can quickly test new ideas and create preliminary screens without the OIT.
Off-line simulation is also great for demonstrating the operation of the OIT and becoming familiar with the
operation of the OIT before it is installed. If you want to simulate the interaction with a PLC when off-line, it can be
done by creating additional windows on the OIT which allow PLC data input.
To use off-line simulation mode from EasyBuilder:
1. If the project has been modified since the last time it was saved and compiled, or if it has not
yet been compiled, it must be saved and compiled before the simulator can start.
