Counters • A counter is basically a register that goes through a prescribed sequence of states upon the application of input pulses – input pulses are usually clock pulses • Example: n-bit binary counter – count in binary from 0 to 2n-1 • Classification 1.

What is the maximum count value for a decade counter? The maximum count value for a decade counter is determined by the number of output bits the counter has. For example, a counter with three output bits (like the one in the earlier example) can count up to a maximum of 2^3 = 8, before it cycles back to zero. Q. PLC Counter Instructions. To illustrate the use of a counter instruction, we will analyze a PLC-based system designed to count objects as they pass down a conveyor belt: In this system, a continuous (unbroken) light beam causes the light sensor to close its output contact, energizing discrete channel IN4. When an object on the conveyor belt . 65 761 280 741 362 532 569 374
