WebAn up-down counter is a combination of an up-counter and a down-counter. It can count in both directions, increasing as well as decreasing. A mode control input (M) is used to select either up or down mode. we have the M (mode control) input which decides whether or should be the clock. input to the next flip flop. WebThe timers and counters are used in a PLC for its continuous operation so they are inevitable in a PLC. The timer would time up to the value set by the user and the counter will count up to the value set by the user. The timer and counter both are of 16 bits, the timers and counters are the fundamental PLC instructions and it is common to all PLCs.
