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'
• 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.
Offset/gain initialization function
The offset and gain values are initialized to the factory default offset and gain values according to the set input type.
Set the mode to the "Normal mode".
Set 'CH1 Input type/Range setting'(Un\G598) to 'CH8 Input type/Range setting' (Un\G1998) as 'Conversion disabled' and
turn offonoff 'Operation condition setting request' (Un\G70, b9).
Set "E20FH" to 'Offset/gain initialization enabled code' (Un\G305).
Turn ON (1) 'Offset/gain initialization request' (Un\G70, b5).
Channels for which the offset and gain have not been set are initialized with the current range.
