How can you generate a frequent square wave using the pulse timers in STEP 7?
In this lesson I’m going to write program for an industrial gas dryer using extended pulse timers.
In this lesson you’ll learn how and where you can use the “Not” instruction.
If you suddenly change the rotation direction of a heavy duty motor, the motor is going to be damaged. In this lesson I’m going to write a PLC program that can protect the motor when it’s going to reverse direction. We’ll change the motor rotation direction without damaging it.
