Chapter 8
Defining Strings for Serial Ports and Viewports
8–39
Example 5 – Using Data Codes and # (Index) Character
The second and third columns in the viewport display (the mean and
standard deviation values, respectively, for gages 1–5) were created using a
single viewport string, along with the
Repeat String feature.
Example 5
Here is the string text used to create the displayed strings:
Here are the elements of the string text used:
•
Data codes are used to display the mean (data code Sn.3 , where n is the
tool type and tool number indicator – see Table 8.A Data Codes in this
chapter) and the standard deviation (data code
Sn.4 ) in the string. In
both cases, we use the # character in place of the n; thus when the string is
repeatedly displayed, the current index number is inserted, designating the
specific tool type and number.
•
Format codes are added to each data code. The format code (7.3) is
added to the data code S#.3 (the mean), setting the width of the
displayed data field to seven places, and limiting the decimal portion of
the field to three places. The format code
(7.4) is added to the data
code S#.4 (the standard deviation), setting the field width to seven
places, and limiting the decimal portion of the field to four places.
