RECONNECT_SUPERVISOR
IEEE 1547 return-to-service supervision: withholds the reconnect permissive until voltage and frequency have held the window for the full stabilization period.
When to use it
Use RECONNECT_SUPERVISOR when a DER or microgrid has ceased to energize and must not return until the area EPS has been demonstrably stable for the period in its interconnection agreement — typically five minutes.

Download RECONNECT_SUPERVISOR — 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 and the datasheet.
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.
