*1. When the optional battery is installed, general type devices can be changed to latched (battery backed) type
devices by the parameter setting. However, the latched range cannot be set.
*2. For applicable functions, refer to Chapter 37.
For handling of the latched area, refer to Section 2.6.

Description
Among 7000 latched type data registers backed
up by the EEPROM, D1000 and later can be set
as file registers in units of 500 points by the
parameter setting.
