Now that we have explained the purpose and function of each word

in the block transfer write block, you should be ready to enter

configuration data. Consult your programming manuals for the

proper techniques required to set up block transfer instructions with

your programmable controller. Refer to chapter 4 for example

programs.

Important: A block transfer write length of 0 will result in a default

length of 13. A block transfer read length of 0 will

result in a default length of 5.

In this chapter, you learned how to configure your module using a

block transfer write instruction.
