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
