Understanding the INIT and Time Zero Steps
The method timed events always start with two steps. The parameters in
these steps can be changed, but the steps cannot be deleted.
• The first step is the INIT (initial conditions) step. The initial conditions
are executed immediately after the method setup.
• The second step is the time zero step, which is executed after the INIT
step. When the time zero step is executed, the timed events clock
begins counting up from zero and any additional timed events run at
their specified times.
NOTE When a cycle time is specified, the AS delays
executing the time zero step until the specified
time has elapsed since the previous injection
(see Section 2.7.5
for details).
Adding Timed Events Steps
1. Use one of the following methods to add a step:
• Move the cursor to the empty TIME field below the last step. Enter
the elapsed time at which to start the new step and press
Enter or
a cursor arrow button.
• Move the cursor to any TIME field and press Insert. This adds a
new step before the cursor position. Enter the elapsed time at
which to start the new step and press
Enter or a cursor arrow
button.
After you add a step, the steps are reorganized in chronological order.
2. Enter the remaining parameters for the new step (see the following
sections).
To retain a value set in the previous step, leave the field blank. A
blank field means there is no change from the previous step.
Deleting Timed Events Steps
To delete a step, move the cursor to the step's TIME field and press Delete
twice.
