Hybrid PLC Mechatronics - Chapter 7 Timers, Counters and T/C Applications

Timers and counters are discussed in this chapter. Timers and counters have been in existence for as long as relays and provide an important component in the development of logic. Practical examples of their use as well as timing diagrams for applications utilizing their specific qualifications are introduced. Examples show a need to be able to use timers in seal or memory circuits. Use of timers and counters together is discussed. An example of a conveyor system counting boxes is discussed and the use of timers and counters to control the movement on the conveyors is shown.
