Hi, i am attaching my spatial logic.vi.In this i have one main pump which runs five smaller pump(SP1 to SP 5) and once the tanks reach 75%,the pumps stop and the recirculating pumps open for 5 sec(SP 6).After that the volume is drained off(SV1) to Interim Storage. The recirculating pumps work fine in the first cycle of loop,but the second time they open for a second even though i have given a time delay of 5 secs.Plz Help. Also i am attaching my second Vi-ARC-Project Vi.As u can see both the VI's have common Interim Storage.As i am new to labview i broke the project in two VI.How do i add the volume collected from VI no 1 and VI no 2 together. Thanks in advance..
