ABB Ability™ Symphony® Plus MR Series

ABB Ability™ Symphony® Plus MR Series

Comprehensive I/O system 

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.

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
