CIP_FLOW_COVERAGE
CIP surface-coverage proof — pipe velocity computed from flow and bore, with a time-at-velocity record and a latched low-velocity event.
When to use it
Use CIP_FLOW_COVERAGE when a CIP circuit is cleaned by turbulent flow through pipework rather than by spray devices, and the cleaning acceptance requires evidence that the minimum surface velocity was achieved and sustained for the wash.

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 and the datasheet.
Every block in the catalogue is free to download, in every format it ships, 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.
