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.

s (2)
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.
Conversion method Conversion cycle
Number of conversion enabled channels  Conversion speed
Sampling processing
Time average
Number of conversion enabled channels × Conversion speed
(The count set to CH1 Time average/Count average/Moving average/Primary delay filter constant setting (Un\G502))  (Number of
Count average
conversion enabled channels  Conversion speed)
Number of conversion enabled channels  Conversion speed
Moving average
Number of conversion enabled channels  Conversion speed
Primary delay filter
*1 Values after the decimal point are omitted.
Ex.
With the following settings, the conversion cycle is 80ms and the actual logging cycle is every 6960ms (integral multiple of
80ms).
• Conversion enabled channel: CH1 to CH8
• Conversion process specification: Sampling processing
• 'CH1 Logging cycle setting value' (Un\G537): 7000
• Logging cycle unit setting: ms
The following values are stored in 'CH1 Logging cycle monitor value' (Un\G441, Un\G442).

■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' (Y9) is turned on and off.
• 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 (1D0H to 1D6H): Setting errors of the logging function
• Error code (1D8H to 1D9H): Setting errors of the logging read function
When 'Operating condition setting request' (Y9) is turned on and off 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: 1D2H) is stored in 'Latest error code' (Un\G0) to turn on 'Error flag' (XF) and the ERR LED.
