4-2-2 Description of Each Area

User Program Area

The CX-Programmer (see note) is used to create the Motion Control Module ladder programs and set the System Setup. Programs and settings are trans- ferred to each Motion Control Module through the peripheral port on the Coor- dinator Module.

The user program is written using ladder diagram programming and executed using a cyclic scan method.
