A/D conversion or D/A conversion processing will not be performed until the
range code is correctly set. After being set, the range code cannot be
changed during operation. The following tables show an example of range
code settings and how the range codes are set in the output words.

Ladder Programming Example for Writing Range Codes
Use SR 25315 (First Cycle Flag: Turns ON for 1 cycle at the start of opera-
tion) and the MOV(21) instruction to write the range code settings. Once the
range code settings have been set, they are recorded by the Board when the
power is ON.
Sets the range codes for analog inputs 1 and 2, and analog output 1
