Siemens PLC Programming with Example
Drive motors via siemens plc
We will drive motors with four separate buttons, each motor has a different run command, and stop command.
And we will add one rule for all motors that motors can run for more than 30 minutes,
If any motor has been on for 30 minutes, a red light will be on and that motor will stop immediately.
Engagement times of the motors are important. Because, even if the start is pressed after the stop button is pressed, every motor cannot be activated until the period that it remains active.
