LOAD_SHARE_KW
Isochronous kW load sharing over a share network — equal per-unit loading by governor trim.
When to use it
Use LOAD_SHARE_KW when two or more generator sets run in parallel on an isolated bus with an analogue or digital load-share line, and each set's governor must be trimmed so all sets carry the same PERCENTAGE of their own rating rather than the same kW.

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.
