Log Output Function Overview
When the input is on, if the log execution input (S3) is turned on, the logged data (D2) is updated regardless of the enable
totalizer input (S2) on/off status. The maximum amount of logged data is 35 items.
When the enable totalizer input is off, totalization is paused. (The accumulated flow volume work area and the accumulated time
work area values are retained.)

Note: For details on the log output function such as the operation immediately after the input is turned on, the operation when the enable totalizer
input (S2) is once again turned on, and the logged data updating when the log execution input (S3) is turned on, see "Log Output Function" on page
