Chapter 8

Defining Strings for Serial Ports and Viewports

8–42

Recall that we also need to create a second string which will have the effect

of erasing the PART REJECTED string when the inspection passes. One

way to do this is to use the Copy and Paste features to copy the PART

REJECTED string to another string. This way both the string text, and the

exact string position, are copied.

Once the PART REJECTED string is copied to another string, we change the

Event setting on this new string so that Master Range and Print on PASS

are selected. Next we change the color on the Color Selection menu to

Clear. This way, when the clear string is “displayed” (it will not actually

appear on the screen), it will have the effect of erasing the PART REJECTED

message.

Example 7 – Using Formulas and Plot Line Codes

Recall that it is possible to draw or plot lines, and/or position strings through

the use of draw line or plot line codes, and that it is possible to use the results

of formulas as draw/plot line parameters. The Tool viewport string in our

example display provides a case in which tool results are used to plot lines

and position strings within the display.

Tool Viewport String

This Tool viewport locates and points out the corner of the part shown in the

monitor image; it also displays the (x, y) coordinates of the corner.
