The Emerson PACSystems PAC8000 Network Interface Modules include PROFINET Bus Interface Modules and traditional bus interface modules. The PROFINET Bus Interface Modules allow connection of PAC8000 I/O to remote hosts via PROFINET. When used as remote I/O, PAC8000 nodes use a Bus Interface Module (BIM) to communicate with the host controller via a local area network (LAN). Different BIMs can be chosen to operate with specific LAN protocols. BIMs are supplied in a number of different package styles according to their function, and each mounts on a dedicated BIM Carrier.
