ABB INNPM12 NETWORK PROCESS MODULE

Description:

• Cnet is a unidirectional, high speed serial data network that operates at a 10-megahertz or two-megahertz communication rate. It supports a central network with up to 250 system node connections. Multiple satellite Cnets can link to the central network. Each satellite network supports up to 250 system node connections. Interfacing a maximum number of satellite networks gives a system capacity of over 62,000 nodes. On the central network, a node can be a bridge to a satellite network, a human system interface, a Harmony control unit (HCU), or a computer connected through a Cnet communication interface. On a satellite network, a node can be a bridge to a central network, a human system interface, a HCU cabinet, or a computer. A human system interface is a workstation that runs Conductor software. A Harmony control unit is comprised of a controller and its I/O devices. A computer can run Composer™ tools, Performer applications, and third-party semAPI applications.
