Logging cycle
■Logging cycle setting
Set the logging cycle with 'CH1 Logging cycle setting value' (Un\G537) and 'CH1 Logging cycle unit setting' (Un\G538).
The following table lists the setting range for each cycle.

The logging cycle must be an integral multiple of the conversion cycle. Even if the setting is not an integral multiple, the actual
logging cycle is adjusted to the integral multiple of the conversion cycle within a limit of the set logging cycle.
The following table lists the conversion cycle for each A/D conversion method.

■When the logging function becomes disabled
The logging is not performed when one of the following errors occurs after the logging function is enabled and 'Operating
condition setting request' (Un\G70, b9) is offonoff.
• Error code (191H): Setting errors of 'CH1 Averaging process specification' (Un\G501)
• Error code (192H to 195H): Setting errors of 'CH1 Time average/Count average/Moving average/Primary delay filter
constant setting' (Un\G502)
• Error code (19DH): Setting error of 'CH1 Digital filter setting' (Un\G570)
• Error code (19EH): Setting error of 'CH1 Digital filter fluctuation width setting' (Un\G572, Un\G573)
• Error code (1D0H to 1D6H): Setting errors of the logging function
• Error code (1D8H, 1D9H): Setting errors of the logging read function
