FX2N-5A Special function block Buffer Memory (BFM) 7
7-51
• The range in which the analog scale value and digital value can be set varies according to
the I/O mode selected for BFM0 and BFM1.
When setting the analog scale value, write the value converted to percentage (1/100).
Example: When input mode 9 (scaling-function voltage input mode: -10 to +10V) is chosen
in BFM 0
If the analog scale value and digital value are outside the selected range set in BFM 0 and
BFM 1, the offset / gain set value errors (BFM 29 b1).
