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

Blurred answer

A conclusion of counter that counts from 00 to 59
What is the out put and the mode if the operation for each one
Because of this, the LEA instructions are more potent than the OFFSET operator.
