■ Totalizer Function
Starting and Pausing Totalization
This section describes the operation from turning on the input to starting and pausing totalization.
Enable totalizer input (S2)
Flow counter
(S1+0, S1+1)
Accumulated flow volume work area
(system work area)
Accumulated time work area
(system work area)
(1) If the input is turned on, the operation status (D1+2), the amount of logged data (D2), 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 while the input is on, sampling of the flow counter starts, and the amount that
the flow counter increased is added to the accumulated flow volume work area with each scan. The accumulated time work
area also starts being measured at the same time.
(3) If the enable totalizer input is turned off, updating the accumulated flow volume work area and the accumulated time work
area is paused.
(4) If the enable totalizer input is once again changed from off to on, the operation is the same as in (2) without initializing the
accumulated flow volume work area and the accumulated time work area.
Ending Totalization
The section describes the operation to end totalization.
Enable totalizer input (S2)
Flow counter
(S1+0, S1+1)
Accumulated flow volume work area
(system work area)
Accumulated time work area
(system work area)
(1) If the input is turned off when the enable totalizer input (S2) is on, updating the accumulated flow volume work area and the
accumulated time work area is stopped. The accumulated flow volume work area and the accumulated time work area
values are retained.
(2) If the input is turned on, the accumulated flow volume work area and the accumulated time work area are initialized to "0".
If the enable totalizer input is on at this time, updating the accumulated flow volume work area and the accumulated time
work area starts.
(3) If the enable totalizer input is turned off, updating the accumulated flow volume work area and the accumulated time work
area is paused.
The processing is the same as (3) in "Starting and Pausing Totalization" on page 27-22.
(4) If the input is turned off, the totalization processing stops. The accumulated flow volume work area and the accumulated
time work area values are retained.
