8.14 Logging Function
The actual logging cycle is "an integral multiple of the conversion cycle of each A/D conversion method".
The following table lists the conversion cycle of each A/D conversion method.
*1 The value after the decimal point is rounded off.
If the set logging cycle is not an integral multiple of the conversion cycle shown above, the logging
function operates in the maximum cycle of an integral multiple within the setting range.
When setting as follows in CH1 to CH3:
• "Averaging process setting": "0: Sampling Processing"
• "Conversion speed setting": "1: 80µs"
• "Logging data setting": "0: Digital Output Value"
• "Logging cycle setting value": 7000
• "Logging cycle unit specification": "0: µs"
80 × 3=240µs
The actual logging cycle is 6960µs (an integral multiple of 240µs).
The actual logging cycle can be checked at CH Logging cycle monitor value (Un\G1122 to Un\G1133)
6. In "Logging points after trigger", set the data points to be collected from stop request (hold
trigger) for logging occurs until logging stops.
The following table lists the setting range of the "Logging points after trigger".
