- Synoptic diagrams.
The directory service provides information via the following subclasses of
DirectoryItem:
- ControlDevice:
input/output properties and constant attributes of accelerator control devices.
- ControlDeviceClass:
meta properties and other attributes of control device classes.
- MetaProperty:
annotated input/output property for acomplishing a task in a generic program.
- DeviceProperty:
input/output property attributes for a device.
- WorkSet:
annotated ordered collection of DeviceGroup objects.
- DeviceGroup:
ordered collection of ControlDevice objects.
- BitPatternDefinition:
the meaning of bitpatterns in status words.
- DeviceMessage:
messages corresponding to bitpatterns or IO errors.
- Accelerator:
attributes of accelerators of the CERN complex (planned).
- AcceleratorSegment:
attributes of segments of accelerators (planned).
- AcceleratorComponent:
attributes of hardware components mounted near the beam (planned).
