Ovation Controller Model OCR1100 Emerson

Real-Time Operating System Functions

The OCR1100 controller processes data for real-time control and communication functions using a commercially available, multi-tasking, real-time operating system. It executes and coordinates the control of multiple application areas by using multi tasking with preemptive priority scheduling. The real time operating system communicates with the Ovation network and other systems via the TCP/IP protocol,

provides some basic routing functions and offers general resource management within the controller.

Hardware

The Ovation OCR1100 controller is built to open industry standards using Intel processors and CompactPCI bus technology. Newer technologies can be easily incorporated while protecting the initial Ovation controller software investment. This foundation provides the portability such that Ovation controller software can be run on other available platforms and operating systems. The Ovation virtual controller used in Ovation simulator systems runs the standard Windows operating system on standard PC hardware and does not require actual I/O interfaces. The hardware platform and the operating systems for the Ovation controller, based on industry standards, offer the following advantages:  Minimal cost and complexity of hardware and software upgrades  Increased ability to track advances in technology

Specifications

The Ovation controller hardware platform has evolved over time beginning with the OCR161 model. Specifications for the OCR1100 model are detailed in the tables within this document. The OCR1100 controller model shares the same packaging concept as the preceding OCR400 model. Migration programs are available to update previous model control logic and databases to the latest model. OCR1100 platform provides backward hardware compatibility and can be used as an OCR400 while retaining the ability to provide full OCR1100 capabilities when installed in an Ovation system release which supports them (i.e. Ovation 3.5 and above).

I/O Capabilities

The Ovation controller supports the concurrent use of several I/O systems depending upon the model used. Like the controller, the I/O system continues to evolve, including support for increased channel capacity modules. Refer to the controller hardware manual and the I/O reference manual for additional details on the available models, capacities, module capabilities and termination types.

Ovation Controller Cabinets

Ovation controllers and I/O modules are all DIN rail mountable, providing the flexibility to match controller layouts with process requirements for various locations, environments and space availability. The normal configuration is to mount DIN rail items on plates which can then be installed in existing or new cabinet enclosures. Top and bottom entry for I/O cables is available to meet required specifications.   A variety of controller and I/O cabinet configurations are available. The basic controller cabinet houses a chassis for single or redundant controllers and two I/O branches on the front of the plate. Mounted on the rear of the plate is a redundant power supply, power distribution module and two additional I/O branches for a total of 32 I/O modules since each I/O branch can hold up to eight I/O modules. Expansion cabinets house up to an additional 32 I/O modules in four branches and a transition panel for connection to the controllers. It can also provide additional space for mounting redundant power supplies (when required), and a power distribution module.   Ovation’s standard cabinet structure is front and rear access, but can be provided with front access only. Other custom or OEM cabinet enclosures are optionally available to accommodate specific requirements for plate sizes, cabinet sizes, construction materials, environmental ratings, cabinet interior and exterior accessories, termination options and marshaling cabinets.  

IEC 61131-3 Compliant

The International Electrotechnical Committee of the ISO organization created a set of standards to achieve uniform mechanisms to configure and program control systems from different vendors. Part 3 of the IEC 61131 directly relates to the standard programming languages recommended to conform to this standard.

The IEC 61131 standard specifies the syntax and semantics of a unified suite of programming languages, including the software model and a structuring language. The standard can be summarized and described under two main categories: Common Elements and Programming Languages. Refer to the Ovation Compliance to IEC 61131-3 data sheet for detailed information Ovation’s adherence to this international standard.

Achilles Certified

Achilles Communications Certification provides an industry-leading benchmark for the secure development of the applications, devices and systems found in critical infrastructure. The certification process is designed to assess the network robustness of industrial devices and certify that they meet a comprehensive set of requirements. It provides device manufacturers with an independently verified result to communicate their product security to customers, while providing the operators of control systems with the most complete, accurate and trustworthy information possible about the network resilience of their deployed products. The Ovation OCR1100 controller complies with the requirements set forth by Achilles Level 1 certification.
