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
• Once the error history storage area becomes full, subsequent error information will overwrite the existing
data, starting from Error history 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 a multiple input module is powered off or the CPU module is reset.
