Introduction:
This chapter covers Sequential Blocks. (also referred to as SB’s). SB’s are made up
of 2 basic elements. Transitions and Steps. Programing SB’s is done using the Graftec
editor. In this chapter, you will learn:
♦ What a SB’s is.
♦ How to call a SB’s.
♦ How to organize several SB’s.
♦ Some typical SB’s structures.
♦ How to program SB’s.
♦ How to structure the program into a pages format.
