Distributed capability

ABB’s S800 and S900 remote I/O and Melody Rack local I/O are connected via high-speed serial

communication buses. Local I/O offers a high packing density to reduce mounting space to

a minimum, whereas remote I/O fully supports distributed system configurations.

Efficient field device integration

Standardized field device tool/device type manager (FDT/DTM) interfaces enable plug-

and-play integration of field devices.

Easy to configure

Module configuration and service is executed using S+ Engineering for Melody and its unrivaled

library of fully tested and field-proven powerful function blocks.

Inherent redundancy design

System-integrated redundancy options for power supply, hardware and communication networks

provide the highest level of availability.

High performance modular network

Symphony Plus MR Series based control systems uses a redundant, high-speed serial communi

cation network with inherent capability for remote communication. 

The network is easy to expand without requiring routing configuration.
