(1) S1 (Source 1): Flow Counter
The flow counter setting differs according to the "(2) Counter Type" on page 27-26 operation type. Starting from the set
device, a number of continuous devices are used according to the data type.
When Counter Type is "Free Run"
Specify the device that stores the counter value that is used to continuously add pulses. To find the number of pulse count
for each scan, calculate it from the difference between the flow counter of the previous scan and latest flow counter.
When Counter Type is "Difference"
Specify the device that stores the number of pulse count for each scan.
The setting range differs according to "(2) Counter Type" on page 27-26.
If Data Type is "Word (W)", the range is 0 to 65,535.
If Data Type is "Double (D)", the range is 0 to 4,294,967,295
*1 The upper and lower data registers change according to the 32-bit data storage method specified. For details, see Chapter 3
"Instructions Reference" - "32-bit Data Storage" on page 3-9.
(2) S2 (Source 2): Enable Totalizer Input
Set the device to enable flow volume totalization.
When the enable totalizer input is off, totalization is paused. When on, totalization is executed.
For details on the enable totalizer input, see "Function Descriptions" on page 27-20.
(3) S3 (Source 3): Log Execution Input
Specify the device to execute and stop the logging process that updates the log and initializes the accumulated flow volume
work area and the accumulated time work area to "0".
When the log execution input changes from off to on, the logging process is executed.
While the FLWP instruction is being executed, execute the next logging process within 119 hours of the previous logging
process.
For details on the log execution input, see "Log Output Function" on page 27-23.
