Description of Line Graph Settings
■ Function
Select Data Log to display a graph created by sampling PLC data (1 or 2
words). Select Broken-line Graph to display a graph of the stored data that is
read from the PLC.
■ Reference
Sampling is specified for each group number using the method set in the NV
Configuration. For the Number of Lines, set the number of lines to be dis-
played. Up to 8 lines can be displayed.
■ Graph Type
Select the method used to plot the graph. Either Pen Move or Sheet Move
can be selected. If Pen Move is set, the graph will be drawn simulating the
movement of a pen. If Sheet Move is set, the graph will be drawn as if the pen
were fixed while the sheet is moved.
■ Direction
Set the direction in which either the pen or the sheet is moved, depending on
the graph type.
Note The display method depends on the graph type and direction set-
tings, so confirm the operation on the PT.
■ Stop Updating
The specified bit can be used to stop updating the display. Updating the dis-
play will be stopped while the specified bit is ON. Sampling will continue.
■ Display Points
Set the number of points that are displayed when plotting the graph. If 100 is
set for Display Point, then the number of records that is set in the PT Configu-
ration must be greater than 100.
