■ Log Output Function
Log output
When the input is on
This section describes the log output operation when the input is on.
Input
Enable totalizer input (S2)
Log execution input (S3)
Flow rate
(S1+0, S1+1)
Accumulated flow volume work area
(D1+4, D1+5)
Accumulated time work area
(D1+6, D1+7)
Logged data (D2)
(1) When the enable totalizer input (S2) is on, if the log execution input (S3) is turned on, the log is updated and the
accumulated flow volume work area and the accumulated time work area values are initialized to "0".
(2) The amount to add calculated from the flow rate (S1+0, S1+1) and the elapsed time is added to the accumulated flow
volume work area.
When the enable totalizer input is on, the sampling period is retained even during the log update processing.
(3) When the enable totalizer input is off, sampling is paused and 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.
(4) Even when the enable totalizer input is off, if the input is on, the log is output in the same manner as (1).
When the input is off
When the input is off, no processing is performed even if the log execution input (S3) is turned on.
Log Updating
The logged data can be recorded from log 1 to log 35. Log 1 is the newest logged data.
Each time the log is updated, 1 is added to the amount of logged data (1) and the old logged data is pushed back by one item (2).
When the maximum amount of logged data is reached, the oldest log is deleted (3).
The date/time information (4) and accumulated flow volume (5) is stored in log 1.
The accumulated time (6) unit is converted from "ms" to "s" and stored in log 1.
(4) Date/time information
Latest log (5) Accumulated flow volume
(6) Accumulated time
When the maximum quantity of logged data is 10
The maximum amount of logged data to use is specified on the Settings tab in the FLWA (Analog Flow Totalizer) dialog box.
Note: For details on the date/time information, the accumulated flow volume, and the accumulated time recorded in the log, see "(5) D2
(Destination 2): Logged Data" on page 27-15.
