FX2N-2LC Temperature Control Block Buffer Memory (BFM) 7

R : Only read is enabled.
R/W : Both read and write are enabled.
✩
: Setting data can be backed up by EEPROM in accordance with the setting of BFM #83.
*1 : Write is enabled when the manual mode transition completion flag is ON.
- As to a numeric value containing a decimal point and numbers after that, set it as a value
multiplied by 10.
Example: 100.0 (actual value)

1000 (set value)
- If a value is written by mistake to a buffer memory used only for read, the written value is
ignored. And 500 ms later, the buffer memory is overwritten with a correct value.
- If a value outside the allowable set range is written to a buffer memory used both for read
and write, the set value range error (b1) of the flag (BFM #0) turns on.
And the buffer memory in which the set value range error has occurred is controlled with
the upper limit or the lower limit of the allowable set range.
