(3) Setting procedure
Follow the procedure below.
1.
Set Enable (0) to Conversion enable/disable setting (Un\G0).
2.
Set Enable (0) to CH Logging enable/disable setting (Un\G1000 to Un\G1007).
3.
Set the type of data to be logged to CH Logging data setting (Un\G1024 to Un\G1031).
CH Logging data setting (Un\G1024 to Un\G1031)
4.
Set the cycle in which logging data are stored to CH Logging cycle setting value (Un\G1032 to
Un\G1039).
5.
Set the unit of the logging cycle in CH Logging cycle unit setting (Un\G1040 to Un\G1047).

The actual logging cycle is an integral multiple of the conversion cycle for each conversion method.
The following table lists the conversion cycle for each 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 set range.
1: When setting as below in CH1 to CH8:
Ex.
• Averaging process setting (Un\G24, Un\G25): Sampling processing (0)
• Sampling cycle setting (Un\G26): 100ms/8CH (3)
• CH Logging data setting (Un\G1024 to Un\G1031): Digital output value (0)
• CH Logging cycle setting value (Un\G1032 to Un\G1039): 1950
• CH Logging cycle unit setting (Un\G1040 to Un\G1047): ms (1)
The conversion cycle is 100ms. The actual logging cycle is 1900ms (an integral multiple of 100ms).
