SIP_7UM_GEN
SIPROTEC-shaped generator protection element set: reverse power (32R), loss of field (40), under/over frequency (81U/81O), under/over voltage (27/59), stator earth fault (64) and backup overcurrent (51), each with its own definite-time stage and a single reported trip cause.
When to use it
Use SIP_7UM_GEN when a synchronous generator's electrical protection has to be modelled or supervised from the PLC — a standby set, a CHP or embedded generator, a site's own generation — and the operator needs to know WHICH element operated, not just that the machine tripped.

Supervised control write
SIP_7UM_GEN commands a real actuator. It is written to sit underneath your own interlock, permissive and protection logic — not to replace it. Commission it as you would any control block you wrote yourself.

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.
