3. Add an Input Contact: Add an input contact to the rung. This represents your button. You'll need to assign it an address (e.g., I0.0 for input 0.0). The input contact will be set as normally open.
4. Add an Output Coil: Add an output coil to the same rung. This represents the output you want to control (e.g., Q0.0 for output 0.0). The output coil represents the light. Assign it an address.
5. Connect Input to Output: Connect the input contact to the output coil. If the input (button) is pressed, the contact will close, and the output (light) will turn on.
6. Compile and Download: Compile your program to check for errors. Download the program to your PLC. Compile the program to ensure there are no errors. To download, connect the PLC and the software, then select the option to download the program. Follow the on-screen prompts to transfer the code.
7. Test the Program: Put the PLC in run mode and test your program. Press the button and see if the light turns on. Monitor the program's execution using the software's monitoring tools.

Example Code

Here's a simplified version of what your Ladder Diagram might look like (This is just a conceptual representation; the actual implementation depends on the software interface):

|--|   |--|
|  | I0.0 |  | Q0.0 |--|
|--|   |--|

In this example:

• I0.0 is the input (your button).
• Q0.0 is the output (your light).

When I0.0 is true (button pressed), Q0.0 becomes true (light on).

This simple example gets you started. From here, you can add more complex logic, using timers, counters, and other functions, to control more sophisticated industrial processes.
