Ex.
The 17th error is stored in error history No.1, and the value "1810" (start address of error history No.1) gets stored to
Latest error code address (Un\G1800).
Latest error code address
(Un\G1800)
● The same process for errors is used when an alarm occurs.
● Once the error history storage area becomes full, subsequent errors will overwrite the previous errors, starting from error
history No.1, and continues sequentially thereafter (Un\G1810 to Un\G1819). (The overwritten history is deleted.)
● The stored error history is cleared when power supply is turned OFF, or when the CPU module is reset.
