PLC Pulse Programming Tutorial Video374

Introduction

Pulse programming is a technique used in programmable logic controllers (PLCs) to control the timing of events. It is commonly used in applications such as conveyor systems, packaging machines, and robotics. Pulse programming can be used to create a variety of different timing patterns, including delays, pulses, and bursts. In this tutorial, we will show you how to use pulse programming in a PLC.

Creating a Pulse Program

To create a pulse program, you will need to use the PLC's ladder logic editor. Ladder logic is a graphical programming language that is used to create PLC programs. It consists of a series of rungs, which are connected by vertical lines. Each rung represents a single instruction. To create a pulse program, you will need to use the following instructions:* Output Coil (O): This instruction turns on or off an output.
* Timer (T): This instruction delays an event.
* Counter (C): This instruction counts events.

Example Pulse Program

The following is an example of a pulse program that creates a 1-second pulse on output O1:```
|----|-----|----|
| O1 | T1 |
| |-----|-----|
| | C1 |
```
In this program, the timer T1 is used to delay the output O1 for 1 second. The counter C1 is used to count the number of pulses that have been created. The output O1 will be turned on when the timer T1 times out and the counter C1 reaches a count of 1. The output O1 will be turned off when the counter C1 reaches a count of 2.

Using Pulse Programming

Pulse programming can be used to create a variety of different timing patterns. It is a powerful tool that can be used to control the timing of events in a PLC program. Here are a few examples of how pulse programming can be used:* Create delays: Pulse programming can be used to create delays of any length. This can be useful for applications such as conveyor systems, where products need to be spaced out evenly.
* Create pulses: Pulse programming can be used to create pulses of any length. This can be useful for applications such as packaging machines, where products need to be sealed or cut.
* Create bursts: Pulse programming can be used to create bursts of pulses. This can be useful for applications such as robotics, where a series of pulses is needed to move a robot arm.

Conclusion

Pulse programming is a powerful tool that can be used to control the timing of events in a PLC program. It is a versatile technique that can be used to create a variety of different timing patterns. In this tutorial, we have shown you how to use pulse programming in a PLC. We encourage you to experiment with pulse programming to see how it can be used to improve your PLC programs.
