You can add a conditional terminal to configure a For Loop to stop when a condition occurs. A For Loop with a conditional terminal executes until the condition occurs or until all iterations complete, whichever happens first. For example, if you want a loop to execute a set number of times unless an error occurs, you can use a For Loop with a conditional terminal and wire an error cluster to the conditional terminal.
Complete the following steps to stop a For Loop when a condition occurs.
|Note If you wire the conditional terminal in a For Loop, you cannot predetermine the number of iterations the loop executes. You can determine the number of iterations the loop completes by auto-indexing an output array and checking the number of elements after the loop executes or by wiring an indicator to the loop iteration terminal and checking the count after the loop executes.|
The number wired to the count terminal or the number of elements in the auto-indexed input array acts as the maximum number of loop iterations that complete if the condition wired to the conditional terminal never occurs. If you want a loop to iterate until a condition occurs with no maximum number of iterations, use a While Loop instead.
