Question
Chapter 8, Problem 1P
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.
Explanation of Solution
b.
Energizing output “O:2/0”:
- The accumulated value of CTU will be incremented by one whenever it receives the conversion input “false-to-true”.
- The DN signal bits will get activated once the accumulate value attains the preset value...
Explanation of Solution
c.
Energizing output “O:2/1”:
- In the given program, “rung 3” does not allow the DN signal bits.
- It means that the output “O:2/1” will be activated for the values which are less than the preset value...
Explanation of Solution
d.
Computing accumulated value:
- Usually the accumulated values of the Programmable Logic Controller (PLC) counters will retain its values even during power off.
- It restores the values until it get the power back...
Explanation of Solution
e.
Accumulated value of the counter:
- The reset mode has been available in the “rung 4” which contains same address “C5:1” of CTU counter.
- The accumulated value of CTU counter will be reset to zero when the “rung 4” turns into “true”...
Explanation of Solution
f.
Situation when the count gets incremented:
- When the “rung 1” input ‘I:1/1” throws “off-to-on” conversion signals, the CTU counter will start its counting process...
Explanation of Solution
g.
Situation when the count gets reset:
- The reset mode will be activated when the “rung 4” becomes true...

- 2. Design a logic circuit with two inputs and 4 outputs, with each of the outputs hooked up to an LED. Only the first LED should light up when the input values are 00. Only the next LED should light up with the input values are 01. Only the following LED should light up for 10, and only the last LED should light up for input 11. Thus for each input combination, you should have one LED only being lit. This is called a DECODER circuit, you are decoding 2 bit binary input to one of 4 discrete outputs. a.
