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…
Interconnection of information technology equipment — Control Network Protocol — Part 2: Twisted-pai...
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…
