• If input M0000 turns on, the result of analog input value D8058 being
converted to the flow rate is stored in D0010 with each scan.
• Sampling of the flow rate D0010 and totalization starts by turning on
input M0000 and enable totalizer input M0050.
• The operation status is stored in D1 (status).
• By turning on M0100 for one scan every day at 00:00 with the WEEK
instruction, S3 (log execution input) turns on and the current log
information is stored in D2 (logged data).
