11 Parameters
11.1 PLC Constants
 Extended area
Up to 750 PLC constants can be secured by using the user backup area (R8300 to R9799) as the extended area. The
extended area start register and number can be set with the parameters. A total of 900 PLC constants can be set with 150
(#18001 to #18150) in the basic area and up to 750 (#18151 to #18900) in the extended area.
Set up data is stored in a file register and is backed up. In contrast, if data is stored in the file register corresponding to PLC
constant by using sequence program MOV instruction, etc., it is backed up.
However, display remains unchanged. Display another screen once and then select the screen again.
750 PLC constants are set (the setting range is ±8 digits). (Signed 4-byte binary data)
