Introduction

The "PSI-Anlagen-Bezeichungssystem" (PAB) has been in use so far for the designation of objects/devices in the three domains, namely: the SLS accelerators, the SLS experiments and the infrastructure. These three domains are identified by the letters A, X, and I respectively, at position 6 in the naming designator.

In this document we define the general structure of the PAB, introduce new domains and give general rules for the definition of the designators. Domain-specific designation rules are defined in subordinate documents. The PAB was first introduced as the "SLS functional naming convention" in 1998 [1], and in 1999 it was extended to the present "PSI-Anlagen-Bezeichungssystem" [2]. The names of existing domains were not adapted, since that would have been much too complex. It was however planned that future domains also follow the PAB convention. In the course of the installation of new hardware for the control system at the proton accelerators, and the structure of new domains, this prescription is now deemed desirable.

This document defines the general structure of the PAB, introduces new domains and gives general rules for the definition of the designators. Domian-specific designation rules are defined in subordinate documents.

Syntax

The naming convention uses capital letter only. In its most general form, a designator follows the syntax:

(Here x means an indication, X a character string, [ ] an optional field.)
Explanation:

• aaaa is the building Prefix (4 positions/characters), e.g. WSLA.
• b is the domain, which it concerns. Each domain has a responsible person and guidelines for the designation of the fields cccc [- D [- E]] [: F]; these must be observed.
• cccc depends on the domain. It is different for a domain (domain A) or Facility (domain I) designated field. It, however, covers all domians accurately in 4 positions. Additional syntax is defined by the person responsible.
• D and E are additional fields, whose syntax is defined by the person responsible. The character string D-E may extend up to a maximum of 12 positions.
• F is a signal (channel) with max. 9 positions.
• G is a condition (status); the length is not defined.

Example

Domain A:

• Field cccc:domain, subdomain (always 2 letters). Fields D-E: arbitrary in the allocation, max. 12 positions, both together. F has max. 9 positions. Field, F, allows numbers and letters, including hypen (-).
• Example: [WSLA-]ARIMA-QLH-05:I-SET.HOPR
  [SLS building -] ring magnets - quadrupole long straight family 'H' - sector 5 : set current . high operating range

Domain I:

• Field cccc: System, group (always 2 letters)
• Field D: System number, group number (always 2 numbers)
• Field E: Block (1 letter), type of apparatus (1 letter), apparatus number (3 numbers)
• Field F: Signal type(2 positions), category (2 positions), system (1 letter), data point number (2 numbers)
• Field G: Status (max. 4 positions)
• Example: OKWA-IKUSK-0101-EY000:D0A1S01.HI
  Kraft/Wärmezentrale - Kühlsystem Sekundärkreis - Kühlsystem 01 Sekundärkreislauf 01 - Elektrotechnischer Apparat, Verstellantrieb Nr 000 - Digital Eingang 0, Alarm Kategorie 1, Siemens, Datenpunkt Nr 01 . hoch

Domain X:

• Field cccc: Sector (2 numbers), source type (1 letter), index (1 letter)
• Field D: Container (max. 4 positions)
• Field E: DEVICE (max. 7 positions)
• Field F: Attributes (max. 9 positions)
• Field G: Signal type, subsystem (max. 4 positions)
• Example: X07MA-OP-MOPG2:CURRENT.HVNC
  Sector 07, M straight, line A - optics - monochromator, getter pump 2 : current . high voltage, not connected

Procedure

• Responsibility: For each domain (or kingdom) the person responsile is listed in the table below.
• New domains and the person responsible are determined by unanimous consent by the authors of this procedure.
  
• The syntactic structure described in the relevant paragraphs should be adhered to.
  Exception: For newly defined domains (or kingdoms) where a naming convention already exists, it is not the intention to change it, but rather use the new names for ancilliary objects (e.g. crates). Changes otherwise are left to the discretion of the person responsible.
