Ovation Certification the OV400 Processor Line What are Possible Quality Reasons? - ✔✔ Latched Quality Tagged Out Hardware Error Oscillating Point Sensor Calibrate Scan Removed Data Link Failure Substituted Entered Value Algorithm Application Test Mode User Definable Engineering Limit Reasonability Limit What are the types of Quality and what is displayed for each next to the point? - ✔✔ Good = none Fair = F Poor = P Bad = B Timed Out = T (not formally defined as a Quality type) For what reasons will a point display Fair Quality? - ✔✔An Operator entered value. The result of a quality checking algorithm in the application (loop propagation). For what reasons will a point display Poor Quality? - ✔✔Generated from certain algorithms if some inputs were bad and some were good. For what reasons will a point display Bad Quality? - ✔✔Faulty input hardware. Input out of specified sensor range (analog). The removal of a point from scan. The result of a quality checking algorithm (loop propagation). Why would a point indicate Timed Out? - ✔✔The point is not being updated. The drop that broadcasts the point is probably off the network. Define the AMS Suite - ✔✔AMS™ Suite (Asset Management System), is a comprehensive and integrated family of applications from Emerson developed for: - predictive maintenance - performance monitoring - and economic optimization. What applications are provided with the AMS Suite? - ✔✔Asset Portal Intelligent Device Manager Machinery Health Manager Equipment Performance Monitor What is the purpose of the Asset Portal? - ✔✔Decision support, reporting and analysis on the health and performance of your production assets. What is the purpose of the Intelligent Device Manager? - ✔✔Predictive and proactive maintenance of instruments and valves. What is the purpose of the Machinery Health Manager? - ✔✔Predictive and proactive maintenance of mechanical equipment. What is the purpose of the Equipment Performance Monitor? - ✔✔Predictive and proactive maintenance of process and mechanical equipment. For which type of devices does AMS work with? - ✔✔- HART field devices - Foundation field bus devices List the types of Analog Input Modules. - ✔✔Analog Input (13 bits) Analog Input (14 bits) Analog High Speed Input (14 bits) HART Analog Input HART High Performance Analog Input RTD 4-Input RTD 8-Input List the types of Analog Output Modules. - ✔✔Analog Output HART Analog Output HART High Performance Analog Output Ovation control systems consist of three elements, what are they? - ✔✔Input consists of analog or digital signals collected from field devices. These devices control some physical operation in the field. Control logic is created in the Control Builder and processes the input information and determines which output functions should be activated. Output consists of analog or digital signals defined by the control logic and sent out to activate the appropriate field devices. What are the the major types of controls schemes? - ✔✔- Sequential Control (digital) - Continuous Modulating Control (analog) - Advanced Control Define Sequential Control Logic control scheme. - ✔✔Sequential control is "instantaneous" in response time if the proper conditions exist (that is, when the input occurs, usually the output follows immediately). For example, when an operator presses the button to start a pump, the pump either starts or it does not. What are the various types of Sequential Control Logic? - ✔✔Boolean - AND, OR, NOR logic. Output = on or off; 1 or 0; yes or no. Ladder logic - Similar to Boolean. Simulates electrical relay system. Define Continuous Modulating Control (analog) logic sheme. - ✔✔Modulating control is not "instantaneous" in response time. It occurs over a given time period. Typically, an operator defines a desired value for a process and the control system works to attain that value. For example, when the desired level or "set point" for a tank is set by the operator, the system cannot obtain that level instantaneously. It takes time to either raise or lower the level until it matches the set point. List the various types of Continuous Modulating Control (analog). - ✔✔PID Control - Proportional, integral, and derivative. Output = results of PID equation. Lead/Lag functions - Nonlinear lead/lag control. Output = function of old output, old input, new input, gain, and lead/lag time constants. Hi/Low/Medium select - Measures and compares inputs. Rate of change limit - Rate of change in input. Output = rate sampled every second. Total, average, weighted averages - Measures and calculates inputs. Output = sum or average of inputs. Sample and hold - Mathematical calculations of sample inputs. Mathematical functions - Sine, Cosine, Sum, Divide, Log, and so forth. Operator Station functions - Keyboard, MA Station Adaptive and auto tuning control - Dynamic functions. Define the Advanced Control scheme. - ✔✔Advanced control uses sophisticated algorithms that can "adapt" control strategies to meet the control process requirements. List the types of Advanced Control scheme. - ✔✔Equipment startup Demineralization Optimal valve settings Plant performance, Opacity, and Low NOx optimization Advanced sootblowing What is the Ovation Control Builder? - ✔✔The Ovation Control Builder is a graphical editor that creates the control logic that runs in the Ovation Controller. This logic consists of algorithms that are placed on functional drawings (also known as control sheets) and direct the control strategy for the Ovation system. Typically, there are many different control sheets linked together to form the complete control structure for an Ovation system. The Control Builder application consists of three main areas or windows, what are they? - ✔✔Main window with the drawing canvas Object Browser Property Editor What is the role of the Control Builder in Ovation? - ✔✔The Control Builder creates the control logic that runs in the Ovation Controller. In addition to editing the control sheets containing the logic, the Control Builder facilitates the integration of the logic into the Controller. Where is the actual editing of the Control Builder accomplished? - ✔✔The actual editing by the Control Builder is done at an Ovation Engineering Station. Here, control sheets, which are SAMA drawings, are created and edited by a control design engineer. Define Algorithm - ✔✔Set of rules, procedures, and mathematical formulas that define a control strategy. Define an Aperiodic Point - ✔✔These are points whose values are scanned "as needed" or "as requested." What is a Control Function? - ✔✔Drawing that contains a graphical representation of a control scheme. Same as a control sheet. What is a Control Task? - ✔✔Refers to a specific Controller area where all the control sheets in that area are scanned at the same frequency. Up to five control tasks can be defined. What are the two system defined control tasks? - ✔✔Control Task 1 area are scanned every 0.1 second or 100 milliseconds (also known as fast time). Control Task 2 area are scanned every 1 second or 1000 milliseconds (also known as slow time). Define Cycle - ✔✔Time interval during which the scanning of inputs, execution of algorithms, and the transmission of output values to devices occur. Define Deadband - ✔✔The range of values through which an input signal may vary without initiating an action of causing an observable change in the output signal.
