Information technology - Control network protocol - Part 3: Power line channel specification
ISO/IEC 14908-3:2011 specifies the control network Power Line (PL) channel and serves as a companion document to ISO/IEC 14908-1. It presents the information necessary for the development of a PL physical network and nodes to communicate and share information over that network.
ISO/IEC 14908-3:2011 covers the complete physical layer (OSI layer 1) including the interface to the Medium Access…
Information technology - Control network protocol - Part 4: IP communication
ISO/IEC 14908-4:2011 specifies the transporting of the Control Network Protocol (CNP) packets for commercial local area control networks over Internet Protocol (IP) networks using a tunnelling mechanism wherein the CNP packets are encapsulated within IP packets. It applies to both CNP nodes and CNP routers.
The purpose of ISO/IEC 14908-4:2011 is to ensure interoperability between various CNP…
Information technology — Control network protocol — Part 2: Twisted pair communication
ISO/IEC 14908-2:2011 specifies the control network protocol (CNP) free-topology twisted-pair channel for networked control systems in local area control networks and is used in conjunction with ISO/IEC 14908-1. The channel supports communication at 78,125 kbit/s between multiple nodes, each of which consists of a transceiver, a protocol processor, an application processor, a power supply and…

Industrial communication networks - High availability automation networks - Part 7: Ring-based Redun...
IEC 62439-7:2011 specifies a redundancy protocol that is based on a ring topology, in which the redundancy protocol is executed at the end nodes, as opposed to being built into the switches. Each node detects link failure and link establishment using media-sensing technologies, and shares the link information with the other nodes, to guarantee fast connectivity recovery times. The nodes have…
IEC 62541-8:2011 is part of the overall OPC Unified Architecture (OPC UA) standard series and defines the information model associated with Data Access (DA). It particularly includes additional VariableTypes and complemental descriptions of the NodeClasses and Attributes needed for Data Access, additional Properties and other information and behaviour.
OPC unified architecture - Part 5: Information Model
IEC 62541-5:2011 defines the Information Model of the OPC Unified Architecture (OPC UA). The Information Model describes standardised Nodes of a server's AddressSpace. These Nodes are standardised types as well as standardised instances used for diagnostics or as entry points to server specific Nodes. Thus, the Information Model defines the AddressSpace of an empty OPC UA server. However, it…
Information technology — Open systems interconnection — Part 1: Object identifier resolution system
ISO/IEC 29168-1:2011 specifies the object identifier (OID) resolution system (ORS), including the overall architecture and a DNS-based resolution mechanism.
It specifies the means for inserting any application-defined information associated with an OID node into the domain name system (DNS) and the means of retrieval of that information using the ORS.
It does not restrict the number of…
