Order of operations for state transitions

[jsturdy]

Brief summary of issue (work in progress...)

Certain applications require a proper sequence of operations

1. GEM applications (GEMSupervisor/hardware managers/etc.)
2. TCDS applications (LPMController/ICIController/PIController)
3. uFEDKIT applications (EVM/BU/FerolController`)

Initialize

Only GEM applications are currently set up to expect this, and at the moment the order doesn't matter, though a future could be envisioned where

• GEMSupervisor is first
• AMC13Manager is next (or)
• in conjunction with the AMCManager
• OptoHybridManager is next

Halt/Stop/Pause

These all can share a similar ordering, as when running, we want to stop the thing furthest from our system first, e.g., TCDS, then move closer

• TCDS should be Halted when GEM applications are Initialized

Configure

Need to configure TCDS first, to ensure that clocks are coming

Start/Resume/Enable

Start applications closest to our system first, and then move away, e.g., TCDS should be last to start

• For uFEDKIT operations, the EVM must be enabled before the BU (but after an RU and TA, if present)

Reset

Probably quite similar to Halt would be sufficient
