How to Work with Delta PLC Simulator?

In this article, I will discuss how to work with the simulator in the delta PLC.

Delta PLCs are quite popular like Siemens and Allen-Bradley, provide an easy interface and easy connectivity.

To work with the simulator in the delta PLC, do follow the below steps to test the PLC ladder logic.

Download: Delta PLC Software

Step 1:

Open Delta PLC. The version I have is WPLSoft 2.9

Make sure that you open up WPLSoft in an administrator mode otherwise, you will face a time-out error.

In the “properties” section do the following setting to run the software in an administrator mode.


Step 2:

Now, open Delta PLC. Create a new project.

Step 4:

Now, let’s write the PLC program to run 5 consecutive motors by pressing the push button. STOP button is used to stop all the motors.

In the delta PLC Input is denoted by X and output is denoted by Y.

Step 5:

Now, let’s test the program in the simulator. To work with the simulator first click on an icon as shown in the below window.

Click on this “code” icon to compile the program.

Step 12:

To test the logic do right click on “X0” and click on “set on” which will turn ON all the outputs.

On the release of the button, it will hold the output status in ON state as I have used “Y0” in parallel with input to latch the outputs.

Step 13:

As you can see all the outputs are set now. If I release the button an output will remain turn ON.
