THERMAL_STORAGE_CTRL
Chilled-water or ice thermal-storage charge/discharge mode selection with state-of-charge guardrails and rate tapering.
When to use it
Use THERMAL_STORAGE_CTRL when a chilled-water or ice storage tank is used to shift cooling load off the electrical peak, and something has to decide each interval whether to charge it, draw from it, or leave it alone.

Download THERMAL_STORAGE_CTRL — 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.
