Field device integration - Part 7 : Communication devices 1 Scope This document specifies the elements implementing communication capabilities called Communication Devices. The overall FDI architecture is illustrated in Figure 1.The architectural components that are within the scope of this document have been highlighted in this illustration. The document scope with respect to FDI Packages is limited to Communication Devices. The Communication Server shown in Figure 1 is an example of a specific Communication Device. 2 Normative references The following referenced documents are indispensable for the application of this document.

HTTP: Hypertext Transfer Protocol IP: Internet Protocol PHY: Physical communication hardware SNMP: Simple Network Management Protocol TCP Transmission Control Protocol URI: Uniform Resource Identifier 3.3 Conventions 3.3.1 EDDL syntax This document specifies content for the EDD component that is part of FDI Communication Packages. The specification content using EDDL syntax uses the font Courier New. The EDDL syntax is used for method signature, variable, data structure and component declarations. 3.3.2 Capitalizations Capitalization of the first letter of words is used in the IEC 62769 series to emphasize an FDI defined term. 3.3.3 Graphical notation This document uses the graphical notation defined in IEC 62769-5. 4 Overview 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 EDD 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 as follows: 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.
