4、millisecond resolution.Ovation ControllerEmerson Process Managements Ovation expert control system incorporates a powerful controller for secure, mission-critical operations such as those of power and water plants. The Ovation Controller executes simple or complex modulating and sequential control s

5、trategies, performs data acquisition functions, and interfaces to the Ovation Network and various I/O sub-systems. It has the capability to originate up to 16,000 points.Process ApplicationsThe Ovation Controller is designed to meet the demanding requirements of a wide range of process applications.

6、 It performs numerous functions, including: Continuous (PID) control Boolean logic Advanced Control Special logic and timing functions Data acquisition Sequence of events processing Cold junction compensation Process point sensor/limit checking Process point alarm processing Process point conversion

7、 to engineering units Process point database storage Local and remote I/O interface Process point tagoutStandard Controller FunctionsControl ExecutionThe Ovation Controller, with its Intel processor,is capable of simultaneously executing as many as five process control tasks at loop speeds ranging f

8、rom 10 milliseconds to 30 seconds.Each control task is comprised of I/O processpoint input scan, the control scheme execution followed by an output scan. Two of the control tasks loop speeds are predefined at one-second and 100 milliseconds. The other three control tasks can have user-selectable loo

9、p speeds.Individual control sheets are user-assigned to one of these tasks, allowing control execution loop times to be appropriate to the functions being controlled.Control SchemeThe control scheme executed by the Ovation Controller is defined by building control sheets with an extensive set of alg

10、orithms. A control sheet is the control that is executed, the documentation of the control, and the online monitoring diagram that is used to run and diagnose the process. The controller can provide for the execution of up to 6,000 control sheets.Sequence of EventsIntegral sequence of events (SOE) p

11、rocessing capability is provided via the Ovation and Q-Line I/O subsystems and standard controller software. With a resolution of one millisecond, the SOE subsystem records the sequence in which a user-defined set of digital input conditions occurred. In addition to the higher resolution time tag, t

12、he SOE points are usable in control schemes like any other I/O point including limit checking and alarming.Alarm ProcessingBased on each process point database definition, the Ovation Controller performs all of the limit and alarm processing functions typically associated with a data acquisition sys

13、tem (DAS). During the input scan associated with the control execution or the default one-second DAS scan. The status (including alarm status) of all points in the controller are updated and broadcast onto the Ovation Network.Extensive information is included within the status information broadcast.

14、 For example, the status may indicate a point has either: Exceeded the range of the sensor Exceeded the user-defined limits Changed state Passed an incremental limitIf desired, the alarm reporting can be delayed on a per-point basis by a user-specified time period.When coupled with a workstation, th

15、e Ovation Controller has the capability to report six independent alarm thresholds, defined as: Four high limits User-defined high limit Highest plus incremental limits Four low limits User-defined low limit Lowest plus incremental limitsThe workstation has the capability to sort alarms based on a u

16、ser-selected alarm significance level. Alarms specified will be denoted as either alert or information when displayed on the alarm screen.Operator Interface ProcessingThe Ovation Controller performs the entire limit and alarm processing based on the database configuration for each point. However, th

17、e controllers operator interface capability allows these functions to be suspended as necessary by the process state or operator action which is also logged. These include scan remove, alarm cutout, enter valve, alarm and limit checking suspension and similar functions, which are also under the Ovat

18、ion security functionality.Controller TypesThe Ovation Controller can provide additionalcapabilities with add-on software licenses for SIM Controller, Advanced Controller, or both.Another licensed controller type is an Ovation Virtual Controller used primarily in Ovation Simulator systems.The SIM Co

19、ntroller is a standard controller that has the ability to be directed to use simulated I/O instead of the actual hardware I/O system.This capability allows the control schemes to be interfaced with a process model or simulation. A basic factory acceptance test process model allows the controller to

20、be tested by simulating the basic I/O functions such as value and direction. The SIM Controller capability can also be used with other fidelity models, such as a High Fidelity process plant model supplied in an Ovation Simulator System. An Advanced Controller is an additional licensed software capab

21、ility that provides the ability to run advanced functionality algorithms. These licensed algorithms include sootblowing, neural networking, fuzzy logic, MPC, DMX, and other advanced algorithms which can use the redundant reliable execution environment provided by the Ovation Controller.The Ovation V

22、irtual Controller is a software licensed capability which recreates the Ovation hardware controller with RTOS on a Windows PC platform. It is used primarily in Ovation Simulator Systems which use non-redundant virtual controllers to decrease the hardware footprint. The Virtual controller has most of

23、 the interface attributes of a standard, SIM or advanced controller except for hardware I/O support.RedundancyThe Ovation Controller is designed to accommodate multiple levels of redundancy for key components, including: Ovation Network interface Functional processor, memory, and network controller

24、Processor power supply I/O interfaces Input power feed I/O power supply Auxiliary power supply Remote I/O communications mediaThe standard hardware configuration for controller redundancy is a passive backplane base on which both a primary and a backup controller are installed. Redundant 24V power i

25、s connected to the unit which is individually distributed to the controllers. Each controller consists of two modules, one providing the processor, memory, Ovation networking, and additional networking connections. The other module provides the interface to both local and remote Ovation and Q Line I

26、/O, plus internal powering.Fully redundant pairs of controllers are equipped with: Dual Intel functional processors Dual network interfaces Dual processor power supplies Dual I/O power supplies Dual auxiliary power supplies Dual input power feeds Dual I/O interfacesEach functional processor in the r

27、edundant pair executes the same application program, although only one accesses the I/O and runs in the control mode at a time. The partner processor runs in the backup, configure, or offline modes with differences between them alarmed.Control ModeIn the control mode, the primary processor functions

28、 as it would in a non-redundant controller. It has direct access to the I/O to read,write, and execute both data acquisition and control functions. In addition, the primary processor monitors the status and health of its backup partners processor and network.Backup ModeIn the backup mode, the backup

29、 processor performs diagnostics and monitors the status and health of the primary processor. The backup processor maintains up-to-date data by polling the control processors database memory and receiving all of the information that the control processor sends over the Ovation Network, including: pro

30、cess point values, algorithm tuning constants, and variable point attributes.Automatic Failover ControlThe redundancy function of the Ovation Controller is equipped with automatic failover control; if the processor in control mode fails, watchdog detection circuitry disables the I/O interface of the

31、 primary processor and informs the backup processor of the failure. The backup processor then takes control of the I/O bus and begins to execute the process controlapplication program and broadcast information over the Ovation Network.Ovation Controllers use a continual process of control memory upd

32、ating to keep both the control and backup processors synchronized.This process uses either the Ovation Network or a private network connection. The employed method is user selectable depending upon control task requirements or available network port usage. This allows the algorithms to track the out

33、put values, pass the information upstream, and apply the data during the first pass of execution. The result is a bumpless failover, even in the case of a malfunction. A full range of events can trigger automatic failover, including: Control processor failure Network controller failure I/O interface

34、 failure Removal of power from the control processor Control processor resetOnce the control is passed to the backup processor, the failed processor may be powered down, repaired, and powered back up with no harmful effects on the executing control strategy.On restart, the repaired processor will de

35、tect that its partner is in control and assume the backup role. The processor in control will detect the presence of the backup processor and adjust for redundant operation.Open ArchitectureThe open architecture of the Ovation Controller uses a powerful real-time operating system running on PCI bus
