PanelView Component Design Considerations
Contents
1. 6 Minutes Upon screen change the PanelView Component will request from the controller updated values for all tags on the screen being displayed Once the objects on the screen are loaded the terminal will only update each object according to its tag update rate While the update rate will determine how often the PanelView Component should ask the controller for data it is possible for the terminal to request the data more frequently than the configured update rate This will occur if all the tags on one screen are requested as part of the same packet If this is the case the terminal will request data from the controller at the fastest rate configured For example one screen has 10 numeric displays with each tag at a different update rate Because all of these tags are optimized into the same packet the PVc will request data for all 10 objects at the fastest rate on the screen Note that packet creation can be further impacted depending upon the application s alarm tags or global connection tags Because alarm tags and global connection tags are constantly being scanned it is possible that the object tags on the screen could be broken up into separate packets Designing Screens Screens can be designed with a myriad of objects to display data or give operators a way of changing values in a controller or a device The recommended limit of 30 objects defines objects as push buttons and numeric displays other objects such as rectangles t2. a user login when opening the editing software Note that secured application will be indicated by a lock icon in the application list of the PanelView Component Startup page e Screen Security used to restrict access to an entire screen Up to 16 users can be created for use with screen and application level security Application and Screen level security is stored within the application itself Terminal security is terminal based and is therefore stored on the terminal It is important to remember that usernames are not case sensitive but that passwords are It is possible to create usernames and passwords that are either numeric or alphanumeric More information about each Application and screen security can be found in the help files of the PanelView Component Terminal Level Security Terminal security is configured through the Startup page The username and password can be configured as well as a timeout period which will automatically log out the user after a period of inactivity Once these items are configured and applied the terminal will reboot requiring the user to login through the web browser PanelView Component Design Considerations v1 05 Rev 1 0 Page 11 of 13 If Terminal Security is enabled and the username and password are lost it is not possible to gain access to the terminal through a web browser The terminal must be reformatted in order to recover the ability to connect to the terminal Application Level Se

5. Each time the PanelView Component switches screens the terminal will request data for the tags on the next screen from the controller Once the data has been acquired from the controller or device the terminal will draw the objects on the screen then populate each object with the appropriate data Due to this process some considerations must be taken into account when designing application screens e Avoid using the wedge arc circle and ellipse shapes and circular scales to improve application loading e Minimize the use of transparency as a background fill color e Avoid overlapping visible objects invisible objects overlapping visible objects are acceptable e Avoid using bar graphs and trend displays with rapidly changing data values see AID 53351 for details Creating Alarms and Alarm Objects Alarm triggers are used to give a visual representation of an alarm state in the controller Each trigger is connected to a separate tag These triggers can be configured as either bit alarms or numeric alarms When an alarm is triggered a message will appear in the alarm banner Alarm tags are scanned constantly while the application is running according to each tag s configured update rate Because alarm tags are constantly on scan be cognizant of the alarm tag update rates such that the system is not overburdened Trending and Data Logging Trending can be used to track data over a period of time while Data Logging can be co
