Motion Control Modules each have independent ladder programming, which
perform processing independently from other Modules. The following diagram
shows the internal structure of Motion Control Modules.

(1) User Memory (UM) Protect 

The following data can be write-protected using settings in the System
Setup.

• User program

• System Setup Area

These Areas are stored in RAM and flash memory.

(2) Part of the DM Area in the I/O Memory Area is backed up by a super ca-

pacitor.

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.
