STRANDED_CAP_CALC
Stranded capacity — the free power that cannot be sold because cooling or space binds first, with the binding resource named.
When to use it
Use STRANDED_CAP_CALC when power, cooling and white space are tracked as three separate capacity pools and the site needs to know how much of its free power is unsellable, and which resource to invest in to release it.

Download STRANDED_CAP_CALC — 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.
