It all starts with naming
3
Gurds Complete HierarchicalDevice and Signal
Naming Convention
SystemDeviceSignal
Eg Linac_DiagnosticsBPM3XPosition
but what device is the signal named after?
4
Gurds Complete Acceleratorand Control System
Drawing
Controller ADC,DAC etc
there are (at least) 3 possibilities
Signal
Answer It should be named after the device it is
a property device
Transducer
Some accelerator device or component eg
Quadrupole, BPM, Vacuum Pump
5
Devices with no measurable properties (eg the
transducer and/or the ADC) can still be named
with the same convention

The Name makes one set of links The RDB makes
the rest

• Signals need to be linked to several devices
  (components)
• The device it is a property of (and is named
  after)
• The tranducer
• The device it plugs in to (Controller, ADC, etc)
• Devices/Components need to be linked to
• The device it passes signal information to
• The device it is housed in
• The device it draws power from
• Information about the equipment (hunk of
  steel) it was
