When the 17th error occurs
The 17th error is stored in 'Error history No.1' (Un\G16 to Un\G21), and 16 is stored in 'Latest address of error history'
(Un\G0).
(Un\G0): 136
Un\G16
Un\G24
Un\G32
Un\G136
• When the storage areas of the error history become full, the histories are overwritten sequentially from
'Error history No.1' (Un\G16 to Un\G21) and error histories are continued to be recorded. The histories
before overwritten are deleted.
• The same processing is performed when alarms occur.
• The recorded error histories are cleared when the power supply of the I/O module with diagnostic functions
is turned off or the CPU module is reset.
