Process Tag Data
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.
