A
■
Error flag (b15)
Error flag (Un\G69, b15) turns on when an error has occurred.
'Error flag' (Un\G69, b15), 'Latest error code' (Un\G0), and 'Latest alarm code' (Un\G2) are cleared at the timing when 'Error
clear request' (Un\G70, b15) turns off
→
on.
Output signals
A state of FX5-8AD can be checked in the buffer memory area.
■ Buffer memory address
The following shows the buffer memory address of this area.

List of output signals
■ Offset/gain initialization request (b5)
Turn off

on
→
off to enable the settings of buffer memory areas.
Offset/gain initialization is not to be performed unless ‘Offset/gain initialization enabled code is set to E20FH.
When 'Offset/gain initialization request' (Un\G70, b5) is off, 'Offset/gain initialization complete flag' (Un\G69, b5) turns off.
■
Operating condition setting request (b9)
Turn off

on
→
off to enable the settings of buffer memory areas.
For the timing of turning the signal off

off User range write request (b10) to register values adjusted with the offset/gain
setting in a multiple input module. The data is written to the flash memory at the timing when this signal is turned off

on.
For the timing of turning the signal off
