56 Module Data, Status, and Configuration
Each output's delay time is configured using one word in the configuration
data file. For OUT0, output delay is configured using bits 0-9 of word 13.
Configure the output delay for OUT1 with word 21; for OUT2 use word 29;
and, for OUT3 use word 37. The following table shows the bits patterns to use
to configure output delay time.

The default delay time is 0 milliseconds.
Refer to Output Delay and Duration Operation on page 18, for additional
information on the module's delay time operation.
Output Duration
When operating in Boolean Control mode, the module's outputs are directed
ON when the Boolean expression for each output is TRUE. The duration
(length of time) the output remains ON can be controlled regardless of how
long the Boolean expression remains TRUE. The ON duration time for an
output starts when that output's delay time has expired. An output's duration
time can be set in 1 millisecond increments between 1 millisecond and
1000 milliseconds (1 second), or, a duration value of 0 can be used to indicate
that the output's ON state should match the duration of the Boolean
equation's TRUE state.
