Problem-1
We like to calculate Total ON time and OFF time for a Shared Variable (PUMP_RUNNING_FEEDBACK) for a Date Range (Start Date and End Date), we are logging the Data in above shared variable.
Problem-2
I want to Calculate the Flow Summary (m3/Day) for an Flow Meter (Analog Input)
Can we generate the above reports using NI Labview or DIAdem.?

Dear M_Atif,
You can implement these Problem statements in Labview.
Problem 1 -
Create a while loop running at 1 loop/sec rate. In each iteration, the current time is evaluated against the start/stop time control input. Based on the status of 'Pump Status' shared variable , registers for On time & Off Time will be incremented. The loop stops when current time>Stop Time input.
Attached the VI snapshot for reference. Try wiring by yourself for other cases in case structures.
Let me know whether it solves your issue.
Problem 2-
What issue are you facing with this requirement? Refer to 'analog input continuous samples ' example in Labview Help Find Example to find a sample VI for this application. You can log the data acquired in a text file using I/O VI & determine flow/day.
Thanks & Regards,
