• Setting of the buffer memories
The contents of the buffer memories set using this function are treated as follows when the
power of the special block is turned off.
- FX -4AD, FX
2N
The setting contents are saved in the built-in EEPROM, and kept stored even if the power
is turned off.
- FX -1HC and FX

The setting contents are saved in the built-in RAM, so they are deleted when the power is
turned off.
When the buffer memories have been set using a sequence program (TO instruction), the set-
ting by the sequence program has the priority.
Use the buffer memory monitor function to perform the initial setting of special blocks and mon-
itor buffer memories.
