112 Creating PowerLine Methods
Note: When creating gradient, event, and detector tables, be sure that you design the
time-related parameters specified in each table to work effectively with the time-related
parameters in the other two tables of the same set.
6.2.1 Documenting the Event Table
Define the information you want in an event table before you actually program the event
table. This will minimize the need for you to reprogram the table later.
Using the Analysis Plan and File Sheet
Appendix C, Analysis Plan, contains an Analysis Plan and File Sheet to assist you in
defining and documenting event table information.
1. Make a photocopy of the Analysis Plan and File Sheet.
2. 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 method determines the total number of
lines. The event table can contain up to 15 lines (14 plus initial conditions). Multiple
events can start at the same time.
Note: If you do not specify Event 8 or 9, 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 the table.
Event Types
There are 10 types of events that you can select, as described in Table 6-2.
Table 6-2 Event Types
Event type Function
1 through 4 Contact closure switches on the rear panel for timed output to
external devices.
5 Internal alarm (reminder to user).
6 Sparge rate for any reservoir enabled on the Pump Setup screen.
7 Column temperature.
8 Go to initial conditions of specified Table #.
