Write a PLC program that will operate a light (Q0.0) according to the following sequence: A momentary contact normally open PB (I0.0) is pressed to start the sequence. The light is switched on and remains on for 5 seconds. The light is then switched off and remains off for 5 seconds. A counter is incremented by 1 after this sequence. The sequence then repeats for a total of five counts. After the fifth count, the sequence will stop and the counter will be reset to zero.

Speed control of motor

Speed control by DC motor-speed controller is required to realize variable speed drive. Whenever a motor drives a particular load, it is called drive, and variable speed drive refers to a load requiring variable speed. All this is obtained by a DC motor speed controller.
