ABB MR Series Ability™ Symphony® Plus control system

ABB MR Series Ability™ Symphony® Plus control system

Scalable, highly available, easy to configure and efficient control system

Continuous productivity improvements and increased profitability are the driving  force behind today’s automation system. Furthermore, systems must support users  with the power to react quickly to ever rising demands from the markets they serve.

Traditionally, production facilities maintained  many controller subsystems, each of which  had to meet specific plant needs. However, as business goals have changed, using a scalable  controller platform that possesses multifunctional capabilities, adapts to changing  requirements, and maximizes openness and availability, is paramount to success.

ABB Ability Symphony Plus MR Series (Melody  Rack) controllers, communication interfaces  and I/O modules meet the most challenging  requirements in each of these areas.

Thanks to their modular design, MR Series  controllers can be adapted to a wide variety  of plant types and sizes. Supported by an  efficient engineering workbench, MR Series  control based solutions contribute to a higher  return on assets by improving overall production  control, maximizing process availability, and  minimizing maintenance.

Features and benefits

·Flexible, cost-effective assembl

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 plugand-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 communication network with inherent capability for  remote communication. The network is easy to expand without requiring routing  configuration.

Overview

The MR Series includes a series of compact DIN  rail mounted controllers, a wide range of I/O  modules and modern, standardized fieldbus  interfaces. These modules offer all the functions required for data acquisition and signal  conditioning, as well as powerful open loop  and closed loop control, sequence control and  monitoring. All process management tasks are executed on the basis of integrated  complex control strategies. Without the need  for configuration, The MR Series inherent  redundancy design – including integrated  redundancy concepts for power supply,  communication and I/O – provides the highest  level of availability.

Key features include:

• A wide range of I/O interfaces with optionally  integrated intrinsic safety (Ex i) design and  transmitter power supply. Features such as  time stamping with a 1 ms resolution, monitoring, filtering and HART communication  are implemented directly in the I/O modules 

• PROFIBUS interfaces provide connections to  ABB’s S800 and S900 remote I/O stations in  Ex and non-Ex versions, as well as other  PROFIBUS devices 

• IEC 61850 interface to intelligent electronic  devices (IEDs) for the integration of electrical  subsystems 

• Modbus RTU and TCP interfaces provide  connections to 3rd party devices

• The MR Series control network uses a  redundant, high-speed serial communication  network with inherent capability for remote  communication. The network is easy to handle,  without requiring routing configuration 

• Flexible mounting alternatives such as cabinet,  DIN rail or 19” rack mounting. All three can be  combined in one project. This allows optimal  adaptation to all plant structures and supports  flexible upgrades of existing installations 

• An unrivaled high packing density in the  system cabinets saves installation space 

• Controller time synchronization based on  a time precision of 0.5 msec
