Emerson Ovation controller model OCR1100

Features Safe and reliable mission-critical control provides "interference-free" automatic failover between redundant controllers. One-step data acquisition function of fast processor to improve productivity, defined by I/O database, has small floor space, low power consumption, and no fan to operate with Ovation and WDPF I/O interfaces, and an integrated virtual I/O function Ethernet protocol system for third-party OEMs through Ovation and digital bus integrated interface I/O modules locally and remotely. Non-volatile storage of application software, integration of point database, configuration information and operation tuning constant, event sequence ability and 1 millisecond resolution meet IEC 61131-3 standard Achilles level 1 certification. Emerson's Ovation distributed control system is famous for providing accurate control. This accuracy begins with the safety of Ovation controller and key tasks such as power generation, water supply and wastewater treatment plants. OCR1100 model of Ovation controller series implements simple or complex modulation and sequence control strategy, data acquisition function of Ovation, interface network and various I/O subsystems. It can generate as many as 32,000 points. The process application Ovation OCR1100 controller is designed to meet all kinds of demanding requirements to process applications. The function controllers executed by include: continuous (PID) control Boolean logic advanced control special logic and timing function data acquisition event processing sequence cold junction compensation.

Process point sensor/limit inspection process point alarm processing process point is converted into engineering unit process point database to store local and remote input/output interface process point listing standard function control execution Ovation OCR1100 controller, using Intel-based processor, can simultaneously execute up to five process control tasks at cycle speed ranging from 10 milliseconds to 300 seconds. Each control task consists of I/O process point input scanning, control scheme execution and output scanning. For Ovation 3.6 and earlier, two control tasks use predefined cycle speeds of one second and 100 milliseconds. The other three control tasks can have a user-selectable cycle speed. Ovation 3.7 software version has a user-selectable loop speed ranging from 10 milliseconds to 300 seconds for all five control tasks. Control scheme OCR1100 functions are defined by the control table from a large number of standard and advanced Ovation algorithms designed for the power, water and wastewater treatment industries. The control table provides the basis for execution, recording and automatically creating the tuning diagram used during control debugging, and when adjusting the control scheme. On average, OCC100 controller can execute more than 1,000 control tables. The complete event sequence processing ability is to use Ovation I/O and standard controller to provide software. The resolution is 1 millisecond, and the event sequence subsystem records the sequence, in which a set of user-defined digital inputs indicate the change of state, providing valuable troubleshooting and diagnostic tools for high-speed electrical systems. In addition to the higher resolution time stamp, the event sequence point can be used to control the same scheme as any other I/O point, including limit check and alarm. The alarm processing OCR1100 processes the limit value and the database definition of each process point of alarm based on the following factors. Whether scanning the points input into the control loop or separating the data acquisition from the control function. The alarm status of each point in the controller is updated every scan. This state may indicate whether the point value has: out of sensor range exceeds user-defined limit; state change exceeds incremental limit; alarm report may be delayed on a per-point basis for a user-specified period of time. When used in combination with workstations, Ovation OCR1100 controller can report six independent alarm thresholds, which are defined as: four upper limits, user-defined upper limits, maximum plus incremental limits, and four lower limits, user-defined lower limits, minimum plus incremental limits. Workstations can classify alarms according to the following contents and display alarm importance levels selected by users. Operator interface processing Ovation controller performs all restrictions and alarms based on database configuration. However, Ovation HMI provides the following functions to suspend the flow status or operator operation of these functions as required.

Controller Type Ovation The function of the controller can be extended to additional software licenses for simulation and virtual control or advanced control. Simulator controller is a standard controller, which uses analog I/O instead of actual hardware I/O system to model or simulate the control scheme and process. The simulator controller can be a basic factory acceptance test flow model or a high fidelity factory model. The algorithm licensed by the advanced controller has advanced functions such as automatic regression, dynamic matrix, equipment, soot blowing, fuzzy logic, time sequence control, programmable module and temperature profile. Virtual controller is a software licensed function, which uses a real-time operating system platform based on Windows. It is mainly used for Ovation simulation, and the solution with non-redundant virtual controller can reduce the hardware space. Virtual controller has most standard interface properties, and it is supported by analog or advanced controller input and output except hardware. The OCR1100 controller is designed to adapt to the multi-level redundancy of key components, including: Ovation network interface function processor, memory and network controller processor power I/O interface input feed input/output power auxiliary power remote input/output communication media controller's standard hardware configuration redundancy is a passive backplane, and both of them are based on it to install the main controller and the standby controller. Redundant 24V power supply is connected to the device and distributed to the controller respectively. Each controller consists of two modules. A module provides the processor, memory, Ovation network and additional network connections. Other modules provide local and remote interfaces Ovation and Q Line I/O, plus internal power supply. Each functional processor in a redundant pair executes the same application program, although it is only an access I/O and runs in control mode for a period of time. Partner processors are running in backup, configuration or offline mode, the difference is that they are alert. Control Mode In the control mode, the main processor has the functions of direct input and output access, reading, writing, data acquisition and control. In addition, the primary processor monitors the status and health of its backups, partners' processors and networks. Backup mode In backup mode, the backup processor performs diagnosis and monitors the status and health of the primary processor. The backup processor maintains the latest data database memory of the control processor by polling and receives all the information sent by the control processor, including process point values, algorithm adjustment constants and variable point attributes. Automatic failover control The redundant function controller of Ovation OCR1100 is equipped with automatic failover control. If the processor in control mode fails, the watchdog detection circuit disables the I/O interface processor of the master device and will fail. The backup processor immediately starts to execute the process control application and broadcasts information through Ovation network. Ovation controller uses continuous control process memory update to keep the control and backup processors synchronized. This allows the algorithm to track output values, pass information upstream and apply data during the first execution.

The result is undisturbed failover, even in the event of a failure. A series of events may trigger automatic failover, including: control processor failure, network controller failure, I/O interface failure, power cut-off of the control processor, and power control processor reset. Once the control is handed over to the backup processor, the failed processor can be powered off, repaired and re-powered, and the control strategy will not be implemented. After restarting, the repaired processor will detect that its partner is in control and assume the backup role. The processor in control will detect the existence of the backup processor and adjust the redundant operation. Data transfer OCR1100 controller can transfer the information of intelligent field devices to any workstation on Ovation network. Users can use asset management solutions, such as Emerson's AMS suite, to remotely manage equipment in smart sites. The open architecture of Ovation OCR1100 controller in open building uses powerful real-time operating system, and runs CompactPCI i-bus PC to design this configuration, which makes the rapidly developing technology easy to integrate into the control system, while protecting software investment. Real-time operating system function OCR1100 controller real-time data processing control and communication function commercial, multi-tasking, real-time operating system. It executes and coordinates the control of multiple application fields by using multi-tasks with preemptive priority scheduling. Real-time operating system, Ovation communication network and other systems provide some basic routing functions and general resource management in the controller through TCP/IP protocol. Hardware Ovation OCR1100 controller is designed to use Intel processor and industry standard CompactPCI bus technology. The updated technology can be easily merged while protecting the initial Ovation controller software investment. This foundation provides portability, and Ovation controller software can be used in other available platforms and operating systems. The application system of Ovation Virtual Controller in Ovation Simulator runs standard Windows operating system on standard PC hardware, and no actual input/output interface is needed. Hardware platform and operating system Ovation controller are based on industry standards, which provide the following advantages: the hardware cost and complexity are the lowest, the software upgrade improves the ability to track the progress of technology, and the Ovation controller hardware platform has been developed over time, starting with OCR161 model. See the table in this document for the specifications of OCR1100 model. The OCR1100 controller model shares the same packaging concept as the previous OCR400 model. Migrator can be used to update the previous model control logic and upgrade the database to the latest model. The OCR1100 platform provides backward hardware compatibility, which can be used as OCR400, while retaining the following functions. When installed in, OCR1100 platform provides complete OCR1100 functions to support their Ovation system versions (i.e. Ovation 3.5 and above). I/O capability Ovation controller supports concurrent use of several I/O systems depending on the model used. Like controllers, I/O systems are constantly developing, including modules that support increasing channel capacity.
