ABB Ability™ Symphony® Plus MR Series (Melody Rack) Features and benefits

Features and benefits

Flexible, cost-effective assembly

Decentralized, DIN rail-mounted controller assembly can be combined with local or remote I/Os.

Comprehensive I/O system

A wide range of local and remote I/O is available with integrated intrinsic safety design and

transmitter power supply options. Features such as sequence of events (SOE) time stamping

(1 ms resolution), monitoring, filtering, as well as HART, PROFIBUS, Modbus RTU and TCP

communication are supported with a wide range of I/Os such as Melody Rack local I/O, ABB’s S800

and S900. and other remote PROFIBUS I/Os.

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.
