Trend group displays
Description
Trend graph displays provide traditional value versus time plots in horizontal or vertical orientation. Up to
six Analog or Digital signal tags can be included on each trend display. This selection lets you configure 4
groups of Trend Displays. Each group may contain a mix of analog signal tags and digital signal tags.
ATTENTION
Displaying Trend Points Logarithmically
If you want trends displayed logarithmically, make sure that the first signal tag selected has
the decimal place setting of 127 (Exponential notation – See “How to Enter Signal Tags” –
page 93). The Trend display will then display all the trends logarithmically.
After you have completed all the group configurations you can select the groups and formats to be
displayed and assign them to a specific operator panel display button. [Refer to O/I Display Buttons (1-8)
Configuration (page 126).]
