Totalizer Function Overview
When the input is on, if the enable totalizer input (S2) is turned on, totalization starts.
When the enable totalizer input is on, the amount that the flow counter (S1+0, S1+1) increased is added to the
accumulated flow volume work area with each scan. The accumulated time work area count also starts at the same time.
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 totalizer function such as the operation immediately after the input is turned on and the operation when the enable totalizer
input is once again turned on, see "Totalizer Function" on page 27-22.
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
27-23.
