    ESS Naming Convention The ESS Naming Convention apply to all devices and signals in technical systems and conventional facilities.

    • operator screens • inventory system • drawings • design schematics • computer software • project databases • equipment name tags • test procedures • other sources of technical

    information at ESS.

  • History

    ESS Naming Convention is based on a standard developed for the Super Superconducting Collider (SSC) and later adopted to other large research facilities: • Spallation Neutron Source (SNS) • Facility for Rare Isotope Beams (FRIB) • International Thermonuclear

    Experimental Reactor (ITER) • Continuous Electron Beam Accelerator

    Facility (CEBAF)

  • Syntax

    SSSS System Convention Name BBBB Subsystem Convention Name DDDD Device Identifier III Device Quantifier TTT Signal type III Signal instance XXX Signal Suffix

    SSSS-BBBB:DDDD-III:TTTIIIXXX Device Name Signal Name

  • Motivation Millions of signals to control and thousands of devices to operate:

    • Short, meaningful and structured names needed for communication and configuration.

    • Can’t rely on high level industrial HMI (barcodes, touch screens, etc.) to operate the facility.

    • Industry standards for naming not applicable - Not human readable. - One of the kind facility.

    A uniform naming convention for ESS will help enforce system integration activities across all divisions.

  • Act Proactively ✓ Establish a naming convention at an early stage of the

    project. ✓ Assign a Naming Czar

    - Assure consistency - Coordinate - Update the naming convention document on implementation details.

    ๏ Communicate, communicate and communicate... - Accelerator, - Target, - Neutron instruments, - Conventional Facilities, - etc.

    ๏ Develop a naming tool - Collect requirements from stakeholders - Name support - Enforce syntax - Assure unique names

  • Guidelines

    • Names shall be short, yet meaningful and organised consistently.

    • Name structure does not need to follow WBS or other project management structures. - These are for optimising design and construction. - Device names can however be used to name

    equipment in these structures. • Databases integration is vital.

  • Devices

  • Definition

    From the ICS point of view, all equipment is modeled as devices. • Device is an abstraction that can represent

    either single pieces of equipment (low level code for interfacing with the hardware) ...

    • ...or higher-level entities of the ICS ( e.g., device models, subsystems, instruments...)

    • Device is the basic unit of granularity of the ICS the smallest that can still be standalone and loosely coupled to other components.

  • … and this is also a device

    This is a device...

    • Devices are not organised hierarchically through the naming convention.

    • Example: There are four cavities inside a cryomodule. Both cryomodule and cavities are devices under the same system and subsystem

    • The hierarchical structure are found in other systems where the names are used.

  • Inventory A device name SSSS-BBBB:DDDD-III depends on where the device it is installed and its function. As such it is not an inventory ID. When a device is replaced, the new device inherits the name. Nevertheless, given the name of a device it shall be possible to look it up in the inventory. The other way around, given the inventory ID it shall be possible to look up the device name.

  • Analysis of SNS Signal List

  • SNS Signal List NS_Signallist.xlsx with 405647 signals names (SSSS_BBBB:DDDDIII:TTTIIIXXX) • 120 System names (SSSS) • 97 Subsystem names (BBBB) • 19350 Device identifiers & qualifiers

    (DDDDIII) SNS Checklist.pdf • 40 System names • 135 Subsystem names • 634 Device identifiers

  • Analysis of SNS Signal List System (SSSS) approximately shows the part of the facility that the device provide services to. • HEBT (High Energy Beam Transport) • SCL (Super Conducting Linac) • Tgt (Target)

    SubSystem (BBBB) approximately shows in what context (or discipline) the device is used • Diag (Beam Diagnostics) • Vac (Vaccum) • LLRF (Low Level RF)

  • How to organise devices?

  • Device Category Structure Expect hundred thousands different devices. In the naming tool the devices types shall be sorted under

    • Level 1: Discipline - RF - Vacuum - Water cooling

    • Level 2: Generic Device Type - Two devices of the same generic type provide the same

    function - Example: RF cavities accelerates the beam.

    • Level 3: Specific Device Type - Two devices of the same specific type are identical from a

    controls perspective and have the same set of control signals.

    - Example: Elliptical cavities.

    In Device Naming Tool Select device type:

    Discipline

    Generic Type

    Device Identifier

    Convention Name

  • Device Identifier DDDD

    Both accelerator and target groups prefer to use generic device identifier DDDD in the names. • Device names shall be constructed

    using the generic device identifier (Level 2).

    • However: Users are responsible for selecting the right specific device type. (Level 3).

  • Area Breakdown Structure System SSSS in the ESS naming convention indicates which part of the facility that the device provide services to. • Name and label ESS zones/sections

    after the systems. Do not use the term System in the Device Naming Tool. Rather, • Ask explicitly: Which part of the facility

    does the device provide services to? - Do NOT ask: Where is the device located?

    • The answer shall be selected from a list.

  • Target

  • • Target has few devices compared to accelerator, however many things are unique.

    • Target already has a PBS organised in two levels. - Referred to as System-Subsystem by the target

    devision. • Devices like pumps, valves etc., appear

    in many subsystems. • There is no desire to use discipline in

    the name.

  • Accelerator

    There are many devices of the same kind in the accelerator in a repetitive pattern. • The accelerator is divided into sections

    - Example High beta (HB) • Sections are in turn is divided into
