Chapter 12, Problem 8RQ
Program Plan Intro
Sequencer instruction:
- In Programmable Logic Controller (PLC), sequencer instructions are used for controlling machines which provides a stepped sequence of repeatable operations.
- It simplifies the ladder logic program by allowing the user to use a single or pair of instructions for performing complex operations.
- Various sequencer instructions can be programmed based on the PLC manufacturer.
