ABB CI854A PROFIBUS-DP/V1 Interface Module

CI854A Classic System 800xA Hardware Selector PROFIBUS DP is a high-speed multipurpose bus protocol (up to 12 Mbit/s) for interconnecting field devices, such as remote I/O, drives, low-voltage electrical equipment, and controllers. PROFIBUS DP can be connected to the AC 800M via the CI854A communication interface. The Classic CI854A includes two PROFIBUS ports to realize line redundancy and also supports PROFIBUS master redundancy. The CI854B is the new PROFIBUS-DP master that replaces CI854A in new installations. Master redundancy in PROFIBUS-DP communication is supported by using two CI854A communication interface modules. This master redundancy can be combined with CPU redundancy and CEXbus redundancy (BC810). The modules are mounted on a DIN rail and interface directly with the S800 I/O system, as well as other I/O systems, including all PROFIBUS DP/DP-V1 and FOUNDATION Fieldbus proficient systems. The PROFIBUS DP must be terminated at the two outermost nodes. This is usually don
