Chapter 8

Defining Strings for Serial Ports and Viewports

8–26

The Repeat String feature enables the CVIM module to repeat a particular

string multiple times for the same event (see “Defining the Event” in this

chapter). This is accomplished through the use of an “index” number, which

is incremented through a range of values – you define this range using the

Repeat String menu.

In configuring the repeat range for a string, you set the Start, the End, and

the Increment values:

Start value

End value

Increment value

During operation in the run mode, when the event conditions are satisfied for

sending the string, the index is set to the Start value, then:

(1) If the End value is greater than or equal to the Start value, the string

is sent.

(2) The index is incremented (according to the Increment value).

The string is sent for each index value, until the index value exceeds the

End value.

For example, to repeat a string 5 times, you can set the Start value to 1, the

End value to 5, and the Increment to 1. The index will increment through

values 1 to 5. Or, you can set the Start value to 6, the End value to 10, and

set the Increment to 1, so the index will increment from 6–10, and so forth.
