Part 7: FDI Communication Devices

FOREWORD
1) The International Electrotechnical Commission (IEC) is a worldwide organization for standardization comprising
all national electrotechnical committees (IEC National Committees). The object of IEC is to promote
international co-operation on all questions concerning standardization in the electrical and electronic fields. To
this end and in addition to other activities, IEC publishes International Standards, Technical Specifications,
Technical Reports, Publicly Available Specifications (PAS) and Guides (hereafter referred to as “IEC
Publication(s)”). Their preparation is entrusted to technical committees; any IEC National Committee interested
in the subject dealt with may participate in this preparatory work. International, governmental and non-
governmental organizations liaising with the IEC also participate in this preparation. IEC collaborates closely
with the International Organization for Standardization (ISO) in accordance with conditions determined by
agreement between the two organizations.
2) The formal decisions or agreements of IEC on technical matters express, as nearly as possible, an international
consensus of opinion on the relevant subjects since each technical committee has representation from all
interested IEC National Committees.
3) IEC Publications have the form of recommendations for international use and are accepted by IEC National
Committees in that sense. While all reasonable efforts are made to ensure that the technical content of IEC
Publications is accurate, IEC cannot be held responsible for the way in which they are used or for any
misinterpretation by any end user.
4) In order to promote international uniformity, IEC National Committees undertake to apply IEC Publications
transparently to the maximum extent possible in their national and regional publications. Any divergence
between any IEC Publication and the corresponding national or regional publication shall be clearly indicated in
the latter.
5) IEC itself does not provide any attestation of conformity. Independent certification bodies provide conformity
assessment services and, in some areas, access to IEC marks of conformity. IEC is not responsible for any
services carried out by independent certification bodies.
6) All users should ensure that they have the latest edition of this publication.
7) No liability shall attach to IEC or its directors, employees, servants or agents including individual experts and
members of its technical committees and IEC National Committees for any personal injury, property damage or
other damage of any nature whatsoever, whether direct or indirect, or for costs (including legal fees) and
expenses arising out of the publication, use of, or reliance upon, this IEC Publication or any other IEC
Publications.
8) Attention is drawn to the Normative references cited in this publication. Use of the referenced publications is
indispensable for the correct application of this publication.

4 General
The abstract term FDI Communication Device represents an entity implementing
communication functions over a network using a specific protocol. The group of FDI
Communication Devices splits into two main groups.
a) The FDI Communication Server is a dedicated OPC UA Server providing access to one or
more field device networks. The FDI Communication Server is specified in Clause 7.
b) The FDI Communication Gateway enables to bridge between different physical networks
or different protocols. The bridging business logic is implemented in the EED component
that is provided with an FDI Communication Package. The FDI Communication Gateway is
specified in Clause 8.
NOTE The main differences between a Gateway and a Communication Server are:in terms of FDI the FDI
Communication Server is a dedicated OPC UA Server providing access to one or more field device networks. A
Gateway is a communication device that enables to bridge between different physical networks or different
protocols. The logical representation of a Gateway device within the FDI Server hosted Information Model enables
the FDI Server to process communication in heterogeneous network topologies.

Figure 2 – FDI communication infrastructure architecture
The FDI Server hosted Information Model contains a representation of the network topology.
(see also IEC 62769-5). The Information Model shown in Figure 2 is an example excerpt to
illustrate how the Information Model used elements reflect the actual network topology.
a) The instance of CommunicationServerType (named CommunicationServerName)
represents the FDI Communication Server. The FDI Communication Server implements
physical communication network access (Communication hardware). Clause 7 describes
related Information Model specifics, required FDI Communication Package content and
handling of elements therein. (For subdevices see IEC 62769-5).
b) The instance of ServerCommunicationDeviceType and ServerCommunication-ServiceType
(named Network_B_Channel) maps to the FDI Communication Server implemented
communication services. The ServerCommunicationDeviceType is specified in 7.3.3. The
ServerCommunicationServiceType is specified in 7.3.4.
c) The instance of CommunicationGatewayType (named Gateway_B1) represents the
physical Gateway. Clause 8 describes the related Information Model specifics, the
required FDI Package content and the handling of elements therein.

Module 2
Module n
IEC 62769-7:2015 © IEC 2015 – 13 –
d) The instance of GatewayCommunicationDeviceType (named Module 1) maps to a physical
or logical module enabling communication to the network to which this module is
connected. The GatewayCommunicationDeviceType is specified in 8.3.2.3. The related
Gateway specifics are described in Clause 8.
e) The instance of GatewayCommunicationServiceType (named
CommunicationServiceProvider_G) represents the Gateways’ ability to process
communication services. The Gateway specific implementation of
GatewayCommunicationServiceType is based on Business Logic that enables to run
communication services in heterogeneous communication networks.
f) A communication relation (more details are described in Clause 6) between a physical
device and the device representation managed by the FDI Server is always associated to
communication service objects that are instances of a
GatewayCommunicationServiceType or ServerCommunicationServiceType. The ability of
instantiating multiple communication service objects supports protocols enables to operate
multiple logical connections between a bus master and a device.
g) The Information Model represents the connections between the physical devices shown on
the left side of Figure 2 based on instances of ConnectionPointType NetworkType and the
depicted relations. ConnectionPointType and NetworkType are specified in IEC 62769-5.

Annex F.
c) Communication devices modularity: The modularity information shall be based on using
the EDDL constructs COMPONENT (see IEC 61804-3).
FDI envisions communication device modularity to cope with communication hardware
providing multiple physical or logical communication channels to access multiple logical or
physical communication networks. Each module element of the whole communication
device shall be described by a separate EDD element.
d) The COMPONENT definition shall be used to support the system implemented topology
configuration. Protocol specific definitions are found in IEC 62769-4:2015, Annex F. The
related COMPONENT definitions are described in 5.2.2, 5.2.3, 5.2.4, and 5.2.7.
e) The Business Logic shall contain a method enabled to validate the network (see 5.2.8).
The validation function considers the elements only directly connected to the network. The
validation function shall be referred by the EDDL specified CHECK_CONFIGURATION
attribute.
f) The Business Logic can contain a method enabled to validate the module configuration
(see 5.2.9) or the network configuration (see 5.2.8). The validation function considers the
elements only directly connected to the related parent element in the topology. The

– 14 – IEC 62769-7:2015 © IEC 2015
validation function shall be referred by the EDDL specified CHECK_CONFIGURATION
attribute.
g) Connection Point data: The Connection Point (see 5.2.4 and 5.2.6) shall be described
through EDDL constructs COMPONENT, COLLECTION and VARIABLE. The
COMPONENT definition associates the Connection Point element to the Communication
Device. The VARIABLE definitions represent the properties of a specific Connection Point.
The COLLECTION represents the Connection Point structure as such. Protocol specific
definitions are found in IEC 62769-4:2015, Annex F.
h) MENU:
The Menu structure shall follow the Menu conventions for PC based applications
according to IEC 61804-4 enabling access to
1) FDI Communication Device Type (Bus) parameters: These parameters shall be made
accessible by means of “offline_root_menu”.
2) Topology Configuration Dialogs shall be made available by means of the menu entry
point “topology_configuration”. Protocol specific definitions are found in IEC 62769-
4:2015, Annex F.
5.2.2 Device component
Each FDI Communication Package shall contain an EDD element describing the device.
