Offset/Gain Initialization Function - Mitsubishi Electric MELSEC iQ-F FX5 User Manual

Ex.
When the 17th error occurs:
The 17th error is stored in Error history No. 1, and the value 3600 (start address of Error history No. 1) is stored to Latest
address of error history.
'Latest address of error history'
(Un\G1): 3600
Un\G3600
Un\G3610
Un\G3620
Un\G3750
• Once the error history storage area becomes full, subsequent error information will overwrite the existing
data, starting from Error history No. 1 (Un\G3600 to Un\G3609), and continues sequentially thereafter. The
overwritten history is deleted.
• The same processing is performed for Alarm history when an alarm occurs.
• The stored error history is cleared when an analog input module is powered off or the CPU module is reset.

Offset/gain initialization function

Offset/gain initialization
This function initializes the offset and gain values adjusted by the offset/gain setting to the factory defaults.
1.
Set the mode to the "Normal mode".
2.
For all channels, set A/D conversion enable/disable setting to A/D conversion disable (1) and turn offonoff
'Operating condition setting request' (Un\G70, b9).
3.
Set "E20FH" in 'Offset/gain initialization enabled code' (Un\G305).
4.
Turn ON (1) 'Offset/gain initialization request' (Un\G70, b5).
Precautions
• The channels for which the offset and gain have been set are initialized to the factory defaults of the execution-time range
type (voltage or current).
• The channels for which the offset and gain have not been set are initialized to the current range.
