Interconnection of information technology equipment — Control Network Protocol — Part 1: Protocol St...
ISO 14908-1:2011 applies to a communication protocol for local area control networks. The protocol provides peer-to-peer communication for networked control and is suitable for implementing both peer-to-peer and master-slave control strategies. This specification describes services in layers 2 to 7. In the layer 2 (data link layer) specification, it also describes the MAC sub-layer interface to…

ISO 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 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 application…
Interconnection of information technology equipment — Control Network Protocol — Part 3: Power line ...
ISO 14908-3:2011 specifies all the information necessary to facilitate the exchange of data and control information over the power line medium for networked control systems used in conjunction with ISO 14908-1.
ISO 14908-3:2011 establishes a minimal set of rules for compliance. It does not rule out extended services to be provided, given that the rules are adhered to within the system. It is the…
Interconnection of information technology equipment — Control Network Protocol — Part 4: IP communic...
ISO 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 14908-4:2011 is to ensure interoperability between various CNP devices that…
