BATT_BMS_MON
Battery string supervision: time-qualified under/over-voltage, cell spread, thermal runaway and a fitness verdict for the autonomy.
When to use it
Use BATT_BMS_MON when a UPS battery string is instrumented for string voltage, per-cell or per-block voltages, temperature and state of charge and health, and the site needs to know not just that the string is alarming but whether it can still be counted on for its rated autonomy.

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.
