■When the logging function becomes disabled
The logging is not performed when even one of the following errors occurs after the logging function is enabled and 'Operating
condition setting request' (Un\G70, b9) is turned offonoff.
• 'CH1 Time Average/Count Average/Moving Average' (Un\G502) setting error: Error code (192H to 194H)
• Logging function setting error: Error code (1D0H to 1D6H)
When 'Operating condition setting request' (Un\G70, b9) is turned offonoff on the condition that the
logging cycle determined by 'CH1 Logging cycle setting value' (Un\G537) and 'CH1 Logging cycle unit setting'
(Un\G538) is shorter than the conversion cycle, an error occurs and logging does not start. A logging cycle
setting disable error (error code: 1D2H) is stored in 'Latest error code' (Un\G0), 'Error flag' (Un\G69, b15)
and the ERROR LED turn on.
■Number of logging data
With 'CH1 Number of logging data' (Un\G436), the number of valid data in 'CH1 Logging data' (Un\G10000 to Un\G19999)
can be checked.
• When the number of collected data points is less than 10000
Address 0
Address 1
Address 2
Address 3
Address 4
Address 5
Address 9998
Address 9999
• When the number of collected data points is 10001 or greater
Address 0
Address 1
Address 2
Address 3
Address 4
Address 5
Address 9998
Address 9999
The number of logging data increases by one each time new data is stored.
When CH1 Logging data (Un\G10000 to Un\G19999) becomes full (Number of logging data = 10000), the next data is stored
in the head address of CH1 Logging data (Un\G10000 to Un\G19999), and the logging operation continues overwriting the
existing data. In this case, the number of logging data is fixed to 10000.
