849
A
*1 The programmable controller CPU with firmware version "28" or later supports these special register areas. However, there are no
restrictions on the version of the R00CPU, R01CPU, and R02CPU.
*2 There are restrictions on the firmware version of the supported CPU module and software version of the engineering tool. ( Page
1008 Added and Enhanced Functions)
*3 Only the standard program is supported. Only the setting value of "LED control setting for program restoration information write status"
can be set for SD384.
*4 The Safety CPU with firmware version "11" or later supports this special register area.
*5 The Process CPU with firmware version "14" or later supports this special register area.

Either of the following two setting can be used.
This setting is written to the setting storage area (system area) by turning
off and on SM384.
■LED control setting for program restoration information write status
Set either of the following to specify whether or not the LED flashes when
the program restoration information is not in the CPU module.
• AFA0H: LED flashing
• AFAFH: Without LED flashing
■Target file setting for the file batch online change
Set either of the following to specify the target file of the file batch online
change For the R00CPU, R01CPU, and R02CPU, this setting is always
"program file/FB file/global label setting file" regardless of the set value of
this relay.
• AFB0H: Program file only
• AFBFH: Program file/FB file/global label setting file
