PROGRAMMING

This chapter explains about programming for RE81WH.
When you apply sample programs introduced in this chapter into the actual system, make sure to verify in
advance that there is no problem with the target system control.
Follow the procedure in Figure 7.1-1 to create a sample program using RE81WH.
The default setting allows you to use either GX Works3 (refer to "6.4 Parameter setting") or the sequence
program to make setting; however, if the setting is made for the first time by using GX Works3, the program
for initial setting can be eliminate, which will reduce time for scanning.
