This docum

4、ent has been prepared as part of the service of ISA toward a goal of uniformity in the field of instrumentation. To be of real value, this document should not be static but should be subject to periodic review. Toward this end, the Society welcomes all comments and criticisms and asks that they be a

5、ddressed to the Secretary, Standards and Practices Board; ISA; 67 Alexander Drive; P. O. Box 12277; Research Triangle Park, NC 27709; Telephone (919) 549-8411; Fax (919) 549-8288; E-mail: standardsisa.org. The ISA Standards and Practices Department is aware of the growing need for attention to the m

6、etric system of units in general, and the International System of Units (SI) in particular, in the preparation of instrumentation standards. The Department is further aware of the benefits to USA users of ISA standards of incorporating suitable references to the SI (and the metric system) in their b

7、usiness and professional dealings with other countries. Toward this end, this Department will endeavor to introduce SI-acceptable metric units in all new and revised standards, recommended practices, and technical reports to the greatest extent possible. Standard for Use of the International System

8、of Units (SI): The Modern Metric System, published by the American Society for Testing Technology and life cycle for wireless equipment and systems; and The application of wireless technology. The Committees focus is to improve the confidence in, integrity of, and availability of components or syste

9、ms used for manufacturing or control, and to provide criteria for procuring and implementing wireless technology in the control system environment. Compliance with the Committees guidance will improve manufacturing and control system deployment and will help identify vulnerabilities and address them

10、, thereby reducing the risk of compromising or causing manufacturing control systems degradation or failure. This ISA standard is intended to provide reliable and secure wireless operation for non-critical monitoring, alerting, supervisory control, open loop control, and closed loop control applicat

11、ions. This standard defines the protocol suite, system management, gateway, and security specifications for low-data-rate wireless connectivity with fixed, portable, and moving devices supporting very limited power consumption requirements. The application focus is to address the performance needs o

12、f applications such as monitoring and process control where latencies on the order of 100 ms can be tolerated, with optional behavior for shorter latency. To meet the needs of industrial wireless users and operators, this standard provides robustness in the presence of interference found in harsh in

13、dustrial environments and with legacy non-ISA100 compliant wireless systems. As described in Clause 4, this standard addresses coexistence with other wireless devices anticipated in the industrial workspace, such as cell phones and devices based on IEEE 802.11x, IEEE 802.15x, IEEE 802.16x, and other

14、 relevant standards. Furthermore, this standard allows for interoperability of ISA100 devices, as described in Clause 5. This standard does not define or specify plant infrastructure or its security or performance characteristics. However, it is important that the security of the plant infrastructur

15、e be assured by the end user. 0.2 Document structure This standard is organized into clauses focused on unique network functions and protocol suite layers. The clauses describe system, system management, security management, physical layer, data link layer, network layer, transport layer, applicatio

16、n layer, gateway, and provisioning. Each clause describes a functionality or protocol layer and dictates the behavior required for proper operation. When a clause describes behaviors related to another function or layer, a reference to the appropriate clause will be supplied for further information.

17、 The following terms will be used in this document to describe device behavior: Mandatory: behavior or a protocol that is required for a device to state compliance with the standard (e.g., symmetrical keys). Optional: behavior or protocol defined in the standard that is not required for compliance t

18、o the standard but, if implemented, shall be compliant with the standard (e.g., asymmetrical keys). Configuration: setting of a parameter that will alter behavior and can be set by the system manager (e.g., network layer hop limit). Configurations where defaults are appropriate will state those defa

19、ults (e.g., network layer hop limit = 64). Capability: ability of device to perform to a specified level (e.g., number of children a router can support). Profiles will specify a minimum capability. Feature: notable characteristic of a device (e.g., battery powered). ISA-100.11a-2011 - 29 - 4 May 201

20、1 Mandatory behavior (also referred to as normative behavior) is denoted by the use of the term “shall”. Non-mandatory behavior (also referred to as informative behavior) is denoted by the use of the terms “may” or “recommended”. The mandatory and optional communication protocols defined by this sta

21、ndard are referred to as native protocols, while those protocols used by other networks such as legacy fieldbus or HART communication protocols are referred to as foreign protocols. 0.2 Disclaimers ISA does not take any position with respect to the existence or validity of any patent rights asserted

22、 in connection with this document, and ISA disclaims liability for the infringement of any patent resulting from the use of this document. Users are advised that determination of the validity of any patent rights, and the risk of infringement of such rights, is entirely their own responsibility. Pur

23、suant to ISAs Patent Policy, one or more patent holders or patent applicants may have disclosed patents that could be infringed by use of this document and executed a Letter of Assurance committing to the granting of a license on a worldwide, non-discriminatory basis, with a fair and reasonable roya

24、lty rate and fair and reasonable terms and conditions. For more information on such disclosures and Letters of Assurance, contact ISA or visit www.isa.org/StandardsPatents. Other patents or patent claims may exist for which a disclosure or Letter of Assurance has not been received. ISA is not respon

25、sible for identifying patents or patent applications for which a license may be required, for conducting inquiries into the legal validity or scope of patents, or determining whether any licensing terms or conditions provided in connection with submission of a Letter of Assurance, if any, or in any

26、licensing agreements are reasonable or non-discriminatory. ISA requests that anyone reviewing this Document who is aware of any patents that may impact implementation of the Document notify the ISA Standards and Practices Department of the patent and its owner. Additionally, the use of this standard

27、 may involve hazardous materials, operations or equipment. The standard cannot anticipate all possible applications or address all possible safety issues associated with use in hazardous conditions. The user of this standard must exercise sound professional judgment concerning its use and applicabil

28、ity under the users particular circumstances. The user must also consider the applicability of any governmental regulatory limitations and established safety and health practices before implementing this standard.
