d <br /> 44 <br /> 11 <br /> CONCENTRIC <br /> INTEGRATION <br /> 7, The following System will NOT be migrated under this contract. <br /> a. Filter system. <br /> b. Nitrate removal system. <br /> c. SCC11 - Raw water pump station <br /> d. SCC10—Dam <br /> e. Bulk storage <br /> f. Power monitoring& efficiency <br /> 8. Redevelop SCADA datapoints (tags) and screens for up to 75% of the City's existing iFix SCADA system <br /> using the style guide developed in section 1a above. Concentric recommends developing the SCADA <br /> Graphics using High Performance HMI Guidelines: <br /> a. Analog values, such as flow rates, pressures, tank levels, etc., will be visualized graphically and <br /> numerically.Graphical depictions of analog process values allow users to glance at SCADA and visually <br /> see whether the value falls within an acceptable range. It also provides benefit to see when a value is <br /> about to go into a warning or alarm condition, enabling users to change the process before an alarm <br /> condition occurs. <br /> b. When values do fall outside the acceptable range,the graphics will alert users three ways: change of <br /> color,text stating the condition,and a visible warning or alarm symbol. <br /> c. High performance graphics omit using unnecessary animated graphics, pictures as backgrounds, and <br /> inconsistent color-coding that can distract users. <br /> d. The color scheme within the graphics will limit the use of color. Color will be specifically used and be <br /> consistent in definition.The colors selected will also consider colorblindness. <br /> e. Graphic displays will typically follow a four-tier hierarchy: <br /> 1. Level 1: Overview of the entire system with only critical KPI's shown <br /> 2. Level 2: Process specific overview with trends show past process behavior. <br /> 3. Level 3:Specific sub-process or site data displayed. <br /> 4. Level 4: Pop-window with capabilities to control the sub-process of site. <br /> 9. A desktop and mobile version of the SCADA graphics will be developed in Ignition: <br /> a. The desktop version will be accessible via web browser. Graphics will scale accordingly to fit various <br /> screen sizes. <br /> b. The mobile version will be accessed via the Ignition Perspective mobile application and optimized for <br /> user on smaller devices. <br /> Project$t 0230159.00 Page No.8 <br />
