Question
Chapter 15.4, Problem 3RQ
Program Plan Intro
Counter:
- It is similar to timer concept.
- It is used to count the changes that are produced by the state of an outside trigger signal.
- It is a Programmable Logic Controller (PLC) instruction that either counts up or down an integer value produced by the change of a bit from “0” to “1” or “false” to “true”.
- In PLC, counter contains three types, namely,
- Up counters
- Down counters
- Up/Down counters
