RECIP_GEN_LINK
Reciprocating-engine genset adapter: governor and AVR bias, lead-compensated synchro-close on positive slip, soft load ramp and reverse-power supervision.
When to use it
Use RECIP_GEN_LINK when a reciprocating genset has to be brought onto a live microgrid bus and then load-shared — the controller must match speed and voltage, close the breaker at the synchronism point, and ramp the set onto its kW share without reverse-powering it.

Supervised control write
RECIP_GEN_LINK 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.
