Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards bodies
(ISO member bodies). The work of preparing International Standards is normally carried out through ISO
technical committees. Each member body interested in a subject for which a technical committee has been
established has the right to be represented on that committee. International organizations, governmental and
non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely with the
International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO 15745-5 was prepared by Technical Committee ISO/TC 184, Industrial automation systems and
integration, Subcommittee SC 5, Architecture, communications and integration frameworks.
ISO 15745 consists of the following parts under the title Industrial automation systems and integration — Open
systems application integration framework
⎯ Part 1: Generic reference description
⎯ Part 2: Reference description for ISO 11898-based control systems
⎯ Part 3: Reference description for IEC 61158-based control systems
⎯ Part 4: Reference description for Ethernet-based control systems
⎯ Part 5: Reference description for HDLC-based control systems

Introduction
The application integration framework (AIF) described in ISO 15745 defines elements and rules that facilitate:
⎯ the systematic organization and representation of the application integration requirements using
integration models;
⎯ the development of interface specifications in the form of application interoperability profiles (AIPs) that
enable both the selection of suitable resources and the documentation of the "as built" application.
ISO 15745-1 defines the generic elements and rules for describing integration models and AIPs, together
with their component profiles - process profiles, information exchange profiles, and resource profiles. The
context of ISO 15745 and a structural overview of the constituents of an AIP are given in Figure 1 of
ISO 15745-1:2003.
This part of ISO 15745 extends the generic AIF described in ISO 15745-1 by defining the technology specific
elements and rules for describing both communication network profiles and the communication related
1) 2)
aspects of device profiles specific to HDLC -based control systems (CC-Link ). CC-Link is based on HDLC
technology.
In particular, this part of ISO 15745 describes technology specific profile templates for the device profile and
the communication network profile. Within an AIP, a device profile instance or a communication network
profile instance is part of the resource profile defined in ISO 15745-1. The device profile and the
communication network profile XML instance files are included in a resource profile XML instance using the
ProfileHandle_DataType as specified in ISO 15745-1:2003, 7.2.5.
AIFs specified using the elements and rules of ISO 15745-1 can be easily integrated with the component
profiles defined using the elements and rules specified in this part of ISO 15745.

HDLC is used in this document as a synonym for ISO/IEC 13239.

CC-Link is the trade name of the CC-Link Partner Association (CLPA). This information is given for the convenience of
users of ISO 15745 and does not constitute an endorsement by ISO of the trade name holder or any of its products.
Compliance to this part of ISO 15745 does not require use of the trade name CC-Link. Use of the trade name CC-Link

requires permission of the CLPA.

description for HDLC-based control systems
1 Scope
This part of ISO 15745 defines the technology specific elements and rules for describing both communication
network profiles and the communication related aspects of device profiles specific to HDLC-based control
systems.
NOTE Generic elements and rules for describing integration models and application interoperability profiles, together
with their component profiles (process profiles, information exchange profiles, and resource profiles) are specified in ISO
15745-1.
This part of ISO 15745 is to be used in conjunction with ISO 15745-1 to describe an application integration
framework.

5 Technology specific elements and rules
5.1 Integration models and IAS interfaces
The AIP developer shall develop the integration model using the rules described in ISO 15745-1, and shall
ensure that the HDLC-based device and communication network profiles (whether representing the interface
requirements or those derived from existing devices/communication networks) include the necessary IAS
interfaces. The IAS interfaces included in the profile shall be identified in the header section (see ISO 15745-
1:2003, 7.2.2).
NOTE IAS interfaces are described in ISO 15745-1:2003, Annex B.
5.2 Profile templates
5.2.1 General
The HDLC-based technology specific profile templates are derived from the generic profile templates specified
in ISO 15745-1:2003, clause 7.

5.2.2 Contents and syntax
ISO 15745 specifies profile templates that are XML schemas (REC-xmlschema-1-20010502 and REC-
xmlschema-2-20010502) and use a common general structure. The device and communication network
profiles based on these templates typically contain:
⎯ information needed to identify the connected device,
⎯ a description of device data that can be accessed via the network,
⎯ a description of the communication capabilities supported by the device,
⎯ additional vendor-specific information.
However, CC-Link technology uses specific legacy ASCII syntax. Hence, for backward compatibility, template
definitions (see Annex A) include the following:
⎯ communication network and device profile templates, as defined in ISO 15745-1,
⎯ ISO 15745 template to encapsulate files with legacy ASCII syntax ("wrapper").
5.2.3 Header
The profile template header defined in ISO 15745-1:2003, 7.2.2, is used for HDLC-based technology specific
profile templates. Each technology uses one or more names to identify the technology or its particular
component(s) (see Table 1). The selected name shall be stored in the ProfileTechnology attribute in the
header section.

ProfileTechnology name Technology
CC-Link CC-Link
CSP CC-Link
5.3 Technology specific profiles
The technology specific communication network profile structure and communication related aspects of device
profile structure based on HDLC technology are described in clause 6. The technology included is CC-Link
(see 6.2).
The related profile template definitions are specified in Annex A.
