PID controllers
PID controllers are managed the same as the input function described in
Trend Logs
Trend logs may be viewed as either a table or graph.
Note
Viewing trend log graphs require the Sun Microsystems Java Virtual Machine
to be installed on your computer. Download the Virtual Machine at
java.sun.com/getjava/download.html
To view a trend log:
1. Choose
Trend Log
from the
Controller Data
list. A trend log list window
opens.
2. Choose a trend log from the list. A window opens and displays the trend
log in table format.
3. Click
Open Graph
. A new window opens in which the controller will graph
the data.
4. Passing the cursor over a point on the graph displays the data value and
the time it was collected in the
Pointer Coordinates
box.
To zoom in on a specific detail:
1. Left click and drag from left to right over the points you want to examine.
