(2) Relationships between programmable controller CPU, master module and AJ65BT-68TD

POINT

Depending on the used CPU module, the devices used in the program examples of this chapter
may not be applicable. For the device setting ranges, refer to the user's manual of the used CPU
module.
For example, when the A1SCPU is used, devices X100, Y100 and later are not applicable. Use
devices such as B and M.
