Function
•
If the scan end condition (s) is on, the execution of this instruction returns to the head of the scan program and executes the
program.
•
If (s) is off, the next instruction is executed.
•
This instruction can only be used in normal scan programs, and can be used as many times as desired.
•
This instruction can specify a startup condition. In this case, if the startup condition and (s) are both on, this instruction is
executed.
