UPS_MONITOR
UPS module status, load, battery and autonomy monitoring with a redundancy-aware load limit.
When to use it
Use UPS_MONITOR when a static UPS module (or module bus) reports mode, input/output power, battery state of charge and predicted runtime over SNMP or Modbus, and the site needs those raw values turned into a mode, a load figure it can plan redundancy on, and alarms it can act on.
Interface

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.
