Function Descriptions
■ Totalizer Function
Starting Totalization
This section describes the operation from turning on the input to starting totalization.
Pausing and Restarting Totalization
This section describes the operation to pause and restart totalization by turning the enable totalizer input (S2) on and off.
(1) If the input is turned on, the operation status (D1+0), the amount of logged data (D2+0), the accumulated flow volume
work area, the accumulated time work area, and the logged data (D2+2 to D2+2+(6×maximum amount of logged data))
are initialized to "0".
(2) If the enable totalizer input (S2) is turned on, sampling starts. The accumulated time work area (D1+6, D1+7) count starts
at the same time.
(3) The amount to add calculated from the flow rate (S1+0, S1+1) when sampled and the elapsed time is added to the
accumulated flow volume work area (D1+4, D1+5).
(4) Afterward the operation in (3) is repeated.
(1) While the totalization is being executed, if the enable totalizer input is turned off, sampling is paused and updating the
accumulated flow volume work area (D1+4, D1+5) and the accumulated time work area (D1+6, D1+7) is stopped. The
accumulated flow volume work area and the accumulated time work area values are retained.
During the period from the previous sampling to (1), the flow rate is not added to the accumulated flow volume work area,
even if it is larger than "0".
(2) If the enable totalizer input once again changes from off to on, totalization restarts.
The processing is the same as (2) in "Starting Totalization" on page 27-11.
(3) The accumulated flow volume and the accumulated time for the sampling period are calculated.
The processing is the same as (3) in "Starting Totalization" on page 27-11.
(4) Afterward the operation in (3) is repeated.
