Make Sequence Menu
A sequence is a list of data pattern blocks and/or subsequence tasks. The
DG2020A executes sequences in the order listed. In the sequence table, repeat
count, trigger wait, event jump and calling subsequences are used, as well as
placing the blocked patterns in a order.
A patterned data or subsequence can be defined in each line in the sequence
table.
A line can be repeated on output from 1 to 65536 times or infinitely.
A line can wait trigger event for output.
A line can be jumped to a specified line by the trigger of event signal.
Figure 3-47 shows an example of a sequence. In this example, two subsequences
SUB1 waiting trigger event, a blocked pattern data BK1 to be infinitely repeated
and jumped to the line 3 on event signal, and blocked pattern data BK4 are
defined.

. Enhanced columns in Figure 3-47 does not become effective unless the
run mode is not set to Enhanced. For enhanced mode, refer to Run Mode Menu
on page 3-73.
As already stated, sequence can call subsequences. Each subsequence is
composed of blocked patterns with specified repeat count.
