System Displays
Pre-built System Template displays provide an “Out-of-the-Box” solution. Using WebAccess, you can download and start controlling without any display building. This reduces the work to build a functioning system and allows commissioning to begin before user-built displays are complete.
System Template Displays allow all Tags, Alarms, Trends, Reports and Operator Actions to be viewed immediately without building a single new graphic. WebAccess “fills in” the Tag Names and Block Names “on-the-fly” in VIEW allowing you to view and control without display building or “connecting” tags to display fields. The System Displays in WebAccess provides all the functionality found in DCS and DDC systems used in process control and facilities automation systems.
Template Displays
User can also modify or create new Template Displays to allow hundreds tags to be viewed using one of a few templates. Pre-built templates displays are supplied with all WebAccess systems for Alarm Summary, Real-Time Trends, Data Log Trends, Faceplate Groups, Alarm Groups, Overview of Faceplate Groups, Alarm Log, and Action Log.
The Block detail displays allow a single graphic display, including animation, to be used to view all blocks tags of the same block type. This dramatically reduces time to implement a system. Additional Block Tags that are added the system a viewed instantly without building or modifying a display. Many drivers come with default block displays for commonly used block types (e.g. PID controllers, Air Handlers and VAVs). The default Analog Point Display allows all analog tags to be viewed using this one display
The engineers and technicians using DRAW can edit template displays. Template displays include Analog Point Detail, Digital Point Detail, Text Point Detail, Parameter Detail, Block Detail, Data Log Trend, Real Time Trend, Alarm Log, Action Log and Faceplate Group and Overview displays.
Blocks
IO Blocks are a type of tag (our competitors call them super tags). Blocks allow multiple data values read or written from automation devices to be grouped into a single object. Blocks are most commonly used to represent PID controllers, VAVs and other multiple value "instruments" found in a control and automation systems. The typical elements of a PID block include Measurement, Setpoint and Output of the controller. For more information, see the chapter dedicated to blocks, Advanced Block, Parameter & Tag Configuration , Chapter 5.
Standard Popup Dialog Boxes
System development is made easier and faster by utilizing the standard Dialog Boxes for user interaction. These boxes are pre-built and popup when a user tries to change a tag (Change Dialog Boxes, one for Analog, Digital and Text tags) or request a display list (User Built Displays, Trend Displays, Data Log Trend Displays, Overview Displays, Faceplate Displays and Alarm Groups.
A partial list of Standard Popup Dialog Boxes are:
· Multi-STATE DISCRETE CHANGE DIALOG BOX
Users can create their own pop-up dialog boxes using:
· Display Groups in ViewDAQ and
· the GOTO URL keymacros and Action Command and bwViewpg.
Scheduled Reports and ODBC Logs
WebAccess also provides displays for VIEW and ViewDAQ that allow Power Users to view past , current and in-progress Reports, and create custom HTML reports based on Fill-in-the blank” from the System Log, Analog Tag Log, Discrete Tag Log, Alarm Log and Action Log. See Reports, chapter 21.
The Scheduler Reports
WebAccess also provides displays for VIEW and ViewDAQ that allow Power Users to view, modify and download Schedules See Scheduler, chapter 18.
