ABB CI858 COMMUNICATIONS - AC 800M COMMUNICATION INTERFACES

The DriveBus protocol is used to communicate with ABB Drives and ABB Special I/O units.

DriveBus is connected to the controller via a CI858 communication interface unit.

The DriveBus interface is used for communication between ABB Drives and AC 800M controller.

The DriveBus communication is especially designed for sectional drive applications for

ABB rolling mill drive systems, and ABB paper machine control systems.

The CI858 is powered by the processor unit, via the CEX-Bus, and therefore does not

require any additional external power source. 

Features and benefits

DriveBus supports Hot Swap A maximum of 24 ABB drives can be connected

to one CI858 and a maximum of two CI858 can be connected to an AC 800M controller.

If more than one ABB drive is connected to the CI858, a branching unit NDBU is needed,

which enables the construction of a logical bus with physical star topology. 

The branching units can be chained.

APPLICATION

The REF543KM127AAAA is a feeder terminal produced by ABB that is used in a wide range of applications. 

Designed for protection, control, measurement and monitoring of medium voltage networks,

the device can be used with different types of switchgear, such as single bus, 

dual bus and dual machine systems, and supports a variety of network types, including isolated neutral networks,

resonant ground networks and partially grounded networks.

It is especially suitable for the protection and control of medium-sized three-phase asynchronous motors, 

as well as the protection and control of shunt capacitor banks for reactive power compensation.
