Screens common for both PLC OfTs and OISs shall first be developed for the CIS and then be modified, if required, for PLC OIT display in order to maintain a consistent look and resolutions. B. Display Screens Organization 1. Screen menu hierarchy shall be pyramid in nature from the perspective of the overall process. Starting at the top level screen, the operator may navigate to progressively more detailed and process specific screens. With each transition into a deeper level with the hierarchy, the display screen will become more focused on a specific process, portion of the process or piece of equipment. 2. Controls for vertical navigation shall be positioned at the top of each display screen. The controls shall depict a button rectangular in shape labeled with the intended destination screen. Vertical navigation may also be achieved by utilizing touch sensitive graphics which depict the equipment or process desired to be displayed. 3. The operator shall be able to navigate horizontally within the hierarchy to related display screens. Controls for horizontal navigation shall be positioned at the bottom of each display screen. Horizontal navigation may also be achieved by utilizing touch sensitive graphics which depict the equipment or process desired to be displayed. 4. Across the bottom of process display screens, readouts for time and date shall be provided. Also across the bottom, right side of the display, as applicable, buttons shall be provided to display the control strategy and to dismiss the window. 5. Within a screen, a combination of "hot spot" and "designation button" navigation methods shall be used to provide a quick jump to the desired screen. A dedicated "Back to Overview Screen" navigation button shall be provided for all level of screens for a quick return to the corresponding "home" position. C. Screen Types 1. Screens of various types shall be used consistent with the intended purpose of the screen. The functionality of each type of screen should remain consistent to minimize operator confusion. Functionality of the various types of screens shall not be mixed. 2. Overview and sub-overview screens typically occupy the entire viewable display area and represent the process in a graphical manner by visually resembling the equipment being monitored. Process flow shall be arranged top to bottom and left to right. Overview screens for each process area are used for conveying the status and process variables of the major process and equipment. Information on the overview screen shall be selective and sufficient to reflect the health of the entire process area being monitored. The overview screen shall have "hot spots" to Treatment Plant Upgrade & Expansion

5 navigate or jump to the sub-overview screens for more details on specific process area or system. Information on the sub-overview screens shall cover all process lines, equipment and instruments for a thorough representation of the specific system. From overview or sub-overview screens the operator typically must navigate to a lower level screen such as the faceplate screen to initiate control action. 3. Panel screens are graphical representations of traditional control panels depicting pilot lights, pushbuttons, meters, etc. Panel screens may vary in size depending on the requirements. Thus, they can be full size screens or pop-up screens which use only a portion of the viewable monitor area. The operator is able to initiate control action such as entering a setpoint, starting or stopping equipment, or changing control mode. 4. Faceplate screens are graphical representations of traditional panel instruments. They depict the faceplate of a single specific instrument or device. The operator is able to initiate control action such as entering a set-point, starting or stopping equipment, changing control mode or acknowledging the alarm associated with that instrument or device. Clicking on the selected instrument or device will popup or initiate the faceplate screen for that instrument. The faceplate templates shall be created for the standard device operations such as analog monitoring and controls, motor controls, valve controls, and discrete monitoring to provide a consistent interface for the operator. 5. Dialog boxes are used for a variety of applications which require the operator to confirm a requested operation. This is a means of safe-guarding against accidental control commands. The dialog box shall contain a text message indicating the action about to be taken and shall provide a means to cancel the operation if so desired. Dialog boxes are also used for specialized operations such as logging on to the system. 6. Alarm management screens are used to display process and control system alarms. The contents of the screen shall be arranged in a tabular fashion. Entries in the alarm table shall be color coded as defined in Color Conventions, above. The following information, as applicable, shall be conveyed in the alarm table: date and time of the alarm, database point designation, type of alarm, value, PLC number and alarm description. The alarm management screen shall provide a means for acknowledging alarms either individually or by page or globally. If audible alarms are enabled at the intended site, a means shall be provided for silencing audible alarms which is at all times accessible or visible to the operator. At physical locations where there is more than one OIS, the operator shall not be required to silence the alarm on more than one OIS. Alarms are categorized by four types listed in order of priority from highest to lowest. a. Major alarm is the highest priority. A major alarm is caused by an abnormal process or equipment condition. A condition which is potentially dangerous to personnel or equipment or violates public health regulatory limits is classified as a major alarm. A major alarm is usually characterized as being a High-High alarm, hardwired alarm, or remote safety shutdown alarm. b. Minor alarm is the next highest priority. A minor alarm is caused by an Treatment Plant Upgrade & Expansion

6 abnormal process or equipment condition. A condition which is not considered mission critical is classified as a minor alarm. A minor alarm may be a precursor to a major alarm. c. Event alarm is the next to lowest priority. An event alarm is generated by operator action such as changing the control mode. d. Informational alarm is the lowest priority. An informational alarm provides a means of conveying important process information to the operator. Informational alarms usually take the form of messages. 7. Report screens shall be used to display static, dynamic text or numerical values, and trending charts in free formatted form that are captured on a periodic basis for various process areas. The displayed report shall be printable. 8. Following are the approximate numbers of additional screens for estimating purpose. The actual number of screen required for the Expansion project may vary but in no way it relieves the Contractor's responsibilities for providing thorough and accurate graphic screens for safe and efficient control and monitoring of the plant operations.

Interface Elements. 1. Operator interaction with interface elements shall be consistent and predictable. Treatment Plant Upgrade & Expansion

7 It is desirable to minimize keyboard input. The following color conventions shall be sued. a. Valve error (blue) b. Valve in transit or changing state (magenta) c. Open, or run states (bright green) d. Close, Stop, Alarm, Fail or Shutdown states (red) e. Other (grey) 2. Text shall be normally colored black. Text may be color coded in accordance with Color Conventions above when used to convey status information. Character size shall be a minimum of 1/8 inch as displayed on the screen. The use of proportional fonts is preferable. The use of all uppercase letters should be avoided except for such uses as database point names, alarms, or process designation abbreviations. 3. Analog value displays may take the form of a digital readout or an analog meter. The color of the value digits shall be coded with the control mode status of the point. The color of the units of measurement shall be coded with the alarm status of the point. If a meter is used, a digital readout field shall supplement the display. 4. Analog value input controls shall have two methods of operation: slider and keyboard entry. Neither method shall allow an invalid entry. The slider entry shall be transmitted only once the operator accepts the entry. 5. Pop-up faceplate shall be provided for each instrument or device that requires control. - END OF SECTION Treatment Plant Upgrade & Expansion
