Trend Display –
The trend module displays analog and discrete points on trend of any tagged system variable. The trend
display can contain up to six variables (plots) – continuously updated. Plot colors, scale (Min, Max),
Cursor Value and time span are selectable. Curve type can either be X/t or XY.
One can store the trend points in a history file for data collection and display. The historian module
includes a dead band (for data storage reduction) and incorporates save on Trigger or Tag Change
selection. The Trend History display also contains time and date selection.
Miscellaneous Displays -
Operation and Process Status Displays –
Operation indication is structured to quickly and accurately determine process status and to allow for
fast response.
Diagnostic Displays –
The unit maintenance functions can be supported by diagnostic displays which provide the user with a
flow-chart type view of the control loops.
Analog and Discrete I/O Displays –
The I/O displays provide a summary of the analog and discrete point values. Each rectangle includes
the abbreviated point name and the value.
Equipment Condition Displays –
Condition display(s) can be provided to illustrate status (Interlock, ESD status, etc.) and pertinent values
of the process equipment.
Detail Display(s)
Displays for calculation and fall-back value settings are typically included to provide an overview of
key parameters.
Reports and Recipes –
Reports can be created without needing any special programming tool (like VB, etc.). Using the report
workstheet and the scheduler, reports can be custom designed and scheduled for display and
transmission.
The recipes module (worksheet) is used to create, load and delete recipes. Recipes, in this case, means a
group of tags that have their values saved and retrieved like a database. The values can be retrieved
from the ASCII file in standard format or the XML format.
