LIGHTING_CTRL
Lighting control with daylight harvesting, schedule, vacancy timeout and a rate-limited fade.
When to use it
Use LIGHTING_CTRL when a dimmable lighting zone is controlled from a schedule and an occupancy sensor, and a photosensor measures the daylight already arriving at the workplane so the electric light can be trimmed back against it.

Download LIGHTING_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.
