FX2N-5A Special function block Buffer Memory (BFM) 7
7-15
The output characteristics such as the offset and gain settings are automatically changed
depending on the settings of BFM 1. A mode change in BFM 1 will also affect the settings of
BFM 45 (offset data), BFM 55 (gain data), and BFM 240 to 249 (Scaling function data). Before
changing offset/gain or Scaling function data, the appropriate output mode specification must
be set, otherwise, the offset/gain or Scaling function data will be overwritten by the default data
of the selected output mode.
The scale over status (BFM 28) value present before the mode change will not automatically
be cleared when performing a mode change.
The default value of BFM 1 is H0000.
The value of BFM 1 is stored in the internal EEPROM (non-volatile). The module contains a
safety function to protect the internal EEPROM from being destroyed when the same value is
accidentally written continuously to BFM 1.
