Ex.
When the 17th error occurs:
The 17th error is stored in Error history 1, and the value 3600 (start address of Error history 1) is stored to 'Latest address of
error history' (Un\G1).
'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 the A/D converter module is powered off, or when the CPU module
is reset.
