VSpin and Access2 events

Each listed semantic operation emits started, completed, or failed lifecycle records. The modern Agilent frontends and the resource-aware legacy Centrifuge and Loader frontends use the same canonical operation names and payload semantics.

VSpin centrifuge

Operation	Primary fields
centrifuge.spin	device, loaded resources, bucket_resources, relative_centrifugal_force, duration, acceleration_fraction, deceleration_fraction

resources includes each plate currently loaded in a VSpin bucket when the spin starts. bucket_resources preserves which physical bucket holds each plate. The event reports the requested cycle parameters. relative_centrifugal_force is the dimensionless multiple of standard gravity conventionally written as x g, PLR’s default unit for relative centrifugal force. The event does not infer an actual measured force or completed duration outside the frontend call’s success or failure lifecycle.

Access2 loader

Operation	Primary fields
centrifuge_loader.load	device, moved resources, source, destination
centrifuge_loader.unload	device, moved resources, source, destination

centrifuge_loader.load moves a plate from the Access2 staging holder to the VSpin bucket at the load position. centrifuge_loader.unload moves a plate in the reverse direction. source and destination are the actual PLR holders involved in the transfer.
