FLOW_TOTAL_DAY
Daily flow totalisation with day rollover, metering-gap validity, reverse-flow rejection and scan-overrun supervision.
When to use it
Use FLOW_TOTAL_DAY when a flow has to be reported as a daily volume — abstraction return, consented discharge, DMA import, works throughput — and yesterday's figure has to survive the day boundary intact for the regulatory record.

Download FLOW_TOTAL_DAY — free
Create a free Ri Tech account to download the block. You get the Structured Text body, the Rockwell Add-On Instruction (.L5X), the Schneider Control Expert DFB (.XDB), PLCopen XML, the IEC 61499 function block type (.fbt) and the datasheet.
Every block in the catalogue is free to download, in every format, with no purchase and no card. Browsing needs no account at all; downloading needs a signed-in one, so the block lands in your library and re-downloads whenever you need it.
Source is never published on this page. The implementation is released to a signed-in Ri Tech account — free of charge, but never anonymously.
