You will use three general procedures in this tutorial.
Setting bits in your initialization words
Reading data from your industrial terminal
Writing data to your industrial terminal
You will observe the results of setting bits in your initialization words by
reading data from or writing data to your ASCII device. The procedures
for reading and writing data were covered in chapter 1. The procedure for
setting bits in your initialization words is covered after you have added
initialization logic to your program.
As in chapter 1, this chapter is divided into two parts. One is for PLC-2
family processors, the other is for the PLC-3 processor. Proceed to the
