First of all, I do not know why you are using PLC S7-1200 for controlling the stepper motor via the L298N module. Generally, one can use a micro-controller for that purpose. However, you can use PLC to realize your system by using a signal conditioning module to convert signals from PLC to a suitable form that can be used to control the L298N module.
To interface S7-1200 to L298N, you will need the following:
An S7-1200 PLC
An L298N motor driver
A power supply
Jumper wires
Once you have gathered your materials, follow these steps:
Connect the power supply to the L298N motor driver.
Connect the S7-1200 PLC to the L298N motor driver using jumper wires.
Configure the S7-1200 PLC to control the L298N motor driver.
Test the system by running a simple program that moves the motor.
Here are some additional details about each step:
Connect the power supply to the L298N motor driver. The L298N motor driver requires 12V DC power. Connect the positive lead of the power supply to the Vcc pin on the L298N motor driver and the negative lead of the power supply to the GND pin on the L298N motor driver.
Connect the S7-1200 PLC to the L298N motor driver using jumper wires. The S7-1200 PLC has a number of digital outputs that can be used to control the L298N motor driver. Connect the digital outputs on the S7-1200 PLC to the IN1, IN2, IN3, and IN4 pins on the L298N motor driver.
Configure the S7-1200 PLC to control the L298N motor driver. The S7-1200 PLC has a number of programming options that can be used to control the L298N motor driver. You will need to configure the S7-1200 PLC to set the speed and direction of the motor.
Test the system by running a simple program that moves the motor. Once you have configured the S7-1200 PLC, you can test the system by running a simple program that moves the motor. The program should set the speed and direction of the motor and then move the motor for a specified period of time.
