[urn] Updated / revised request: URN Namespace Registration Request for "PNO"

["Steindl, Guenter" <[e-mail]>]

Dear IETF / IANA,

we would like to request the registration of a URN namespace with the following details:



Namespace Identifier:     pno

Version:                           1

Date:                                2024-05-14

Registrant:
The PROFIBUS Nutzerorganisation e.V. (PNO) [PNO] is an international association that promotes and supports the development of PROFIBUS and PROFINET, industrial communication protocols used in automation technology.
We provide standards, certification programs, and resources to ensure product interoperability and reliability, fostering collaboration among manufacturers, system integrators, and end-users.


  *   Organization: PROFIBUS Nutzerorganisation e.V. (PNO)
  *   Email: [e-mail]<mailto:[e-mail]>
  *   Phone: [phone]

Purpose:
These PNO specified URNs will be part of next editions of e.g., "PROFINET" as part of the IEC61158/IEC61784 at the IEC.
PROFINET is an industry technical standard for data communication over Ethernet, designed for collecting data from, and controlling, equipment in industrial systems, with a particular strength in delivering data under tight time constraints. It is managed by PNO and is used in automation applications, for manufacturing and process automation.
PROFINET is a communication protocol for automation over Ethernet, primarily used to network a variety of devices in a production environment. Here are the key types of resources that can be described and managed using PROFINET:

  *   Controllers: Often known as Programmable Logic Controllers (PLCs) or similar devices, PROFINET enables real-time communication between these controllers and connected devices.
  *   Field Devices: This includes sensors and actuators that provide data or perform physical actions in a production line. Sensors might measure parameters like temperature or pressure, while actuators could be motors, valves, or switches.
  *   Drive Systems: Components such as frequency converters and servo motors, controlled via PROFINET for precise movement in machines.
  *   Robot Control: PROFINET facilitates rapid and precise control of robots for assembly or packaging tasks.
  *   Human Machine Interfaces (HMI): Operator interfaces and visualization systems that allow monitoring and control of processes.
  *   Safety Devices: Safety-related devices and systems, such as emergency stop switches or safety light barriers, can also be integrated into PROFINET networks, often through specialized protocols like PROFIsafe.
  *   Network Components: Infrastructure components like switches and routers that manage data transmission over the industrial Ethernet network.

Syntax:
URNs within the "pno" namespace will follow the following structure:

  *   urn:pno:{PNOresource}:{ResourceSpecificString}

where "PNOresource" is a US-ASCII string that conforms to the URN syntax requirements [RFC8141] and defines a specific class of resource type. Each resource type has a specific labeling scheme that is covered by "ResourceSpecificString", which also conforms to the naming requirements [RFC8141].

Assignment:
PNO maintains a registration authority, the PNO Registration Authority (PNO CO), that will manage the assignment of "PNOresource", and the specific registration values assigned for each resource class.

Security and Privacy:
There are no additional security considerations other than those normally associated with the use and resolution of URNs in general, which are described in Functional Requirements for URNs [RFC1737], URN Syntax [RFC2141], and URN Namespace Definition Mechanisms [RFC3406].

Interoperability:
No known potential issues related to interoperability.

Resolution:
Resolution mechanisms are not intended or anticipated for URNs assigned within the URN namespace.

Documentation:
These PNO specified URNs will be part of next editions of e.g., "PROFINET" as part of the IEC61158/IEC61784 at the IEC.

Please let us know if any additional information or documentation is required for the registration process.

Thank you for your attention to this matter.
