BASELOAD_CTRL
Fixed-kW baseload control of a mains-paralleled set, with setpoint limiting and bumpless transfer.
When to use it
Use BASELOAD_CTRL when a generator set runs in parallel with the utility and must hold a constant real-power output — a fixed export, a fuel-contract baseload, or a CHP set following its heat load — while the utility takes the swing.
Interface

Download BASELOAD_CTRL — 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, 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.
