PARTICLE_COUNT_MON
Non-viable particle monitoring against EU GMP grade / ISO 14644 limits with sample-flow proving.
When to use it
Use PARTICLE_COUNT_MON when a remote or portable non-viable particle counter reports ≥0.5 µm and ≥5 µm concentrations from a classified area, and those concentrations have to be compared continuously against the grade limits and recorded.

Download PARTICLE_COUNT_MON — 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.
