Emerson Ovation ™ Controller Model OCR1100

Emerson Ovation ™  Controller Model OCR1100 

Product Overview

Ovation ™  The Controller Model OCR1100 is a controller in Emerson's Ovation distributed control system, known for its precise control and excellent performance, suitable for critical task operations such as power generation and water supply and drainage. It can execute simple or complex adjustment and sequential control strategies, complete data acquisition functions, and interface with Ovation network and various I/O subsystems, generating up to 32000 points.

Main characteristics

Reliability and safety: It has the ability to control critical tasks safely and reliably, and can achieve disturbance free automatic fault transfer between redundant controllers; Obtained Achilles Level 1 certification, compliant with IEC 61131-3 standard.

Efficiency: Using Intel processors, it can simultaneously execute up to 5 process control tasks with a wide range of loop speeds (10 milliseconds to 300 seconds), and different software versions have different settings for task loop speeds.

Interface and compatibility: Can interface with local and remote Ovation and WDPF I/O interfaces; Integrate interface with digital bus through Ovation I/O module; Capable of integrating virtual I/O and connecting to third-party OEM systems via Ethernet protocol; Supports multiple smart device protocols, such as Foundation ™  Fieldbus, PROFIBUS, DeviceNet, etc.

Storage and functionality: non-volatile storage applications, point databases, configuration information, and operational adjustment constants; The event sequence function with a resolution of 1 millisecond can record the sequence of digital input state changes and can also be used for control schemes; Sensors/limit checks, alarm processing, engineering unit conversion, database storage, etc. that can handle process points.

Structural features: small size, low power consumption, fanless operation; Adopting an open architecture based on CompactPCI ®  Bus design and real-time operating system facilitate the integration of new technologies and protect software investments; The hardware is based on industry standards and uses Intel processors and CompactPCI bus technology, making it easy to upgrade and port.

Controller type

Simulator controller: using simulated I/O instead of actual hardware I/O system, integrating control scheme with process model or simulation interface, can be used for factory acceptance testing, etc.

Advanced controller: executes authorization algorithms with advanced functions, such as autoregression, dynamic matrix, fuzzy logic, etc.

Virtual Controller: Reproduces Ovation hardware controllers using real-time operating systems on Windows based platforms, mainly used for Ovation simulation solutions, without hardware I/O support.

Redundant functions

Redundant configuration: Key components (such as network interfaces, processors, power supplies, etc.) have multi-level redundancy, and the standard hardware configuration is a passive backplane, with a main controller and a backup controller installed.

Working mode: The main controller directly accesses I/O in control mode, performs data acquisition and control functions, and monitors the backup controller; The backup controller performs diagnostics in backup mode, monitors the main controller, and keeps data updated by polling the main controller database.

Automatic fault transfer: When the main controller fails, the backup controller immediately executes the control application program to achieve disturbance free switching. Multiple events can trigger fault transfer, and the fault processor can restore the backup role after repair.

Technical specifications

Basic parameters: The bus structure is based on the CompactPCI standard; Processor reference frequency 1.1 GHz; 1 GB of flash memory and 256 Mb of RAM; Four 10/100 Mb Ethernet NIC ports with two options; The working environment temperature and humidity have corresponding ranges; The size is 20 "w x 8" h x 7 "d; The power supply is 24 VDC 40W.

I/O capability: Supports multiple I/O systems, with up to 16 independent branches for local Ovation I/O, totaling 128 modules; 48 cards per local Q-Line I/O node, and expanding Q-Line I/O can add 1 node; Remote node interfaces also have corresponding support capabilities; Capable of virtual I/O through Ethernet TCP/IP and standard protocols.

Cabinet specifications: The standard controller cabinet and expansion cabinet have the same size (79x24x24 inches), but there are differences in weight, capacity, etc; There are also regulations on the temperature and humidity range for work and storage.

Other information

The controller and I/O modules are both installed on DIN rails, and the cabinet configuration is flexible with multiple options. Customized cabinets can also be provided.

The hardware platform is constantly evolving and compatible with previous models, providing migration programs to update old model control logic and databases.
