Developing Your First Program
A practical way to learn how to program PRO31 is by creating a simple control program.
Example: Blinking an LED
- Goal: Turn an LED on and off with a delay.
Steps:
1. Define an output variable, e.g., `LED_Output`.
2. Use a timer to create delay intervals.
3. Program logic:
- Turn `LED_Output` ON.
- Wait for a specified duration.
- Turn `LED_Output` OFF.
- Wait again.
- Loop the process.
Sample Ladder Logic:
```
|---[Timer T1]---(Set LED_Output)---|
|---[Timer T1 Done]---(Reset LED_Output)---|
```
This simple program introduces key concepts like timers, outputs, and looping.
