Double-click
on the tag row and select the "Data" tab to view the Process Tag's
data in real-time. The grid data is updated immediately when the
source tag fires an event. This is in contrast to the other grid
displays that are updated on a screen refresh timer. The default
buffer size is one.
Name
- Use this to assign a meaningful name to the tag. The name is used
to identify tags in the data grid displays.
Description - Addition information can be stored with the tags
using the Description field.
BufferSize - Sets the buffer size in memory for storing and viewing data
samples. The range is limited to 1-1000 samples.
Clear
Buffer - Clears the buffer.
Array
Data Tooltip - Array values are separated by commas in the
grid's value column. Click on the buffer index (row) to view the
real-time data for that buffer position in the tooltip. You can navigate
the window to other positions in the buffer and still view your
selection in the tooltip.
Buffer
Bar - The buffer bar is a visual indicator of the current buffer use
and view window position. The
full length of the bar represents the capacity of the buffer. The
blue filled in area represents the amount of the buffer that has been
used and the smaller green box represents the position and size of the view
window in the buffer.
VCR
Controls - The VCR type controls at the bottom of the form allow you to
navigate the view window through the buffer.
