Controls

The control plane the beamline runs on, and the seam CORA's edge conducts over. Control plane: BLISS / Beacon / Tango / IcePAP.

ID28 runs on the ESRF BLISS / Beacon control stack over Tango and IcePAP, the same house-style as ID32. The device handles above are bound from the public BLISS Beacon device database (gitlab.esrf.fr/id28/beamline_configuration), carried confirm pending staff verification (CTRL-1); they are BLISS axis / controller names (PI_E518, F700, hfm_ctrl, tth_multilayer, a2_inca) and Tango device URLs, modelled as opaque edge handles over the ControlPort. The IXS acquisition (the meV incident-energy scan, set by the F700 crystal temperature against the fixed-angle multi-analyzer arm, the two-theta moves that set the momentum transfer, the per-analyzer counting on the P201 cards via the MUSST timing chain) runs through BLISS sequences; that orchestration is the seam CORA's edge replaces, conducting over Tango / IcePAP rather than replacing BLISS. The detector file-writing to the ESRF data store is plumbing CORA observes, not data it owns (see model.md).
