TOTALIZER
Scan-rate-independent flow or energy totaliser with a declared rate time base, low-flow cutoff and reverse-flow handling.
When to use it
Use TOTALIZER when a rate has to become a quantity — flow into volume, power into energy, current into amp-hours — for billing, for a water or energy balance, for a batch, or for a cycles-of-concentration calculation.
Interface

Download TOTALIZER — 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.
