Program Example 3:
1. The status of each device when executing CJ instruction:
¾
The method of using this CJ instruction is similar to the method of using goto instruction of
C-language. When executing CJ instruction, the status of each device will not be changed.
¾
When the timers are driven and encounter the execution of CJ instruction, the timing will
resume. After the timing target is reached, the output contact of the timer will be On.
¾
The counter will stop counting (This is because the counter is activated to count via the
software).
¾
All the instructions which have encounterd the execution of CJ instruction will not be
activated.
2. Y1 is a dual output. When M0 = Off, Y1 is controlled by M1. When M0 = On, Y1 is controlled by
M12.
