ABB CI855 COMMUNICATIONS - AC 800M COMMUNICATION INTERFACES

The MasterBus 300 (MB300) communication protocol used in communication between controllers,

and operator stations in installations based on Advant OCS with Master software is also

implemented in the System 800xA controller AC 800M. MB 300 communication is realized in AC 800M

by communication interface , which is connected to the CEX-Bus through a baseplate.

The baseplate, TP853, houses RJ45 connectors for two Ethernet ports,

for network redundancy and provides a simple DIN-rail mounting.

A key benefit of the CI855 interface is the possibility of having peer-to-peer communication

between new plant sections with System 800xA using the AC 800M controller and existing sections

with MB 300-based controllers like Advant Controller 410, Advant Controller 450, and MasterPiece 200/1.

The outstanding I/O capability in REC670 enables control of several bays with complete measurement with only one IED. 

For instance, one REC670 IED is capable of handling control of all apparatuses 

in one entire diameter in 1 ½ breaker arrangement including breaker failure protection for all breakers.

The REF 543 feeder terminal is designed for protection, control, 

measurement and supervision in medium voltage networks.

The REF 543 feeder terminal can be used with different kinds of switchgear, 

including single busbar, double busbar and duplex systems.

The protection functions also support different types of networks, such as, isolated neutral networks, 

resonant-earthed networks and partially earthed networks. 

REC670 IEDs (Intelligent Electronic Device) provide control solutions for any type of switchgear and different switchgear configurations. 

The customized REC670 gives you the freedom to select the functionality entirely according to your needs. 

The pre-configured REC670 variants simplify handling since the basic functionality is included and pre-configured. 

If needed, you can add optional functions to easily increase the functionality of 

the REC670 IEDs to meet the specific requirements of your switchyard.

REC670 integrates advanced voltage control for transformers in a substation in a single IED. 

The IEDs feature a large HMI for local control and instant access to important data, 

such as settings, events and disturbance information.
