Creating an Event Table 183
2. Before you program the event table (see Section 10.2.2, Programming the Event
Table), develop the table by writing each change as an individual line on the
Analysis Plan and File Sheet.
On each line of the Analysis Plan and File Sheet, write:
• Time of event
• Event type
• Event action or setting
The number of events needed to execute the gradient determines the total number of
lines in the table. The event table can contain up to 15 lines (14 plus initial
conditions). Multiple events can start at the same time.
Note: If Event 8 or 9 is not specified, the last condition established remains in effect
when the run time expires.
3. When the table entries are complete, keep the Analysis Plan and File Sheet as a
permanent record of your event table.
Event Types
There are 10 types of events that you can select, as described in Table 10-2.
Once set, each event remains in its set state until you change it.
