Program Plan Intro

Count-Up (CTU) Counter:

The CTU counter refers to an up counter

This counter is used to count an event that occurs logically or externally and places that value in the counter’s accumulator.

The accumulated value can even be maintained during false rung conditions and can be reset back to 0 using reset instruction.

Count-Down (CTD) Counter:

The CTD counter refers to a down counter

It decrements the accumulated value at each false-to-true transition and it also retains the accumulated value as soon as an on/off power cycle occurs.

Explanation of Solution

b.

Accumulated count of counter CTD:

It is given that 20 on/off transitions occur at input “A” and 5 on/off transitions occur at input “B”.

The CTU and CTD counters are addressed at the same location “C5:2”.

The up-counter and down-counter operates simultaneously to increment and decrement the accumulated count value...

Explanation of Solution

c.

State of output A:

Here, the accumulated count value of CTU counter is 15.

The output “A” gets activated only when it receives CU signals from the counter “C5:2”.

But, the preset value is set for 10...

Explanation of Solution

d.

State of output B:

Here, the accumulated count value of CTD counter is 15.

The output “B” gets activated only when it receives CD signals from the counter “C5:2”.

But, the preset value is set for 10...

Explanation of Solution

e.

State of output C:

Here, the accumulated count value of up/down counters is 15 and it is greater than the preset value 10 in the counters addressed at “C5:2’...
