RE PEAT STEP
The Repeat Command is used to repeat Steps in a procedure a defined number of times. To use this
Command, you will tell the application what Steps you want to Repeat and how many times you want
them repeated. The Repeat Step command creates a “jump” back to a specific Step in a Method that
executes the defined Step plus all following Steps up to the Repeat command (i.e. it creates a Method
loop).
TO INSERT A STEP REPEAT SEQUENCE IN A METHOD:
1. From the Method Main screen, choose Step Definition to enter the Method Steps Summary screen.
2. Highlight (select once) the Method Step that you want the repeat step to follow.
3. Choose the Add Step button to access the Method Steps Menu screen.
4. Choose Advanced Options to enter the Set Advanced Options screen.
5. Choose Repeat to insert the Repeat Step function into the Method.
6. Select the Step(s) you would like to repeat from by selecting the Step button twice or selecting once
and then choosing Accept.
Figure 68: Advanced Options Repeat Step screen. Choosing Repeat brings you to a listing of the available steps
in the Method.
7. Enter the number of repeats using the keypad then choose the Accept button to save your change and
return to the Method Steps Summary screen.
This command creates a loopback to the designated Step in a Method, executing the selected Step,
plus all subsequent Steps up to the point of insertion of the Repeat command. For example, in Figure
72, if the Repeat command is set to repeat Step 2 one time, the system will loop back to Step 2 and
execute both Steps 2 and 3 one additional time.
