8.10 FNC 09 – NEXT / End a FOR/NEXT Loop
Program example
1. Program with three FOR-NEXT loops
The loop [3] is repeated 4 times.
When the data value (current value) of D0Z
(D4 when Z is "4") is "6", the loop [2] is
repeated 6 times.
When X010 is OFF
When K1X000 is "7", the loop [1] is repeated
7 times.
When X010 is ON
The program execution jumps to the pointer P22,
and the loop [1] is skipped.
Number of times of repeating the loops [1],
[2] and [3]
X010 = ONX010 = OFF
7 × 6 × 4 =168 times
6 × 4 = 24 times
