Program FOR(512) and NEXT(513) in the same task. Execution will not be
repeated if these instructions are not in the same task.
A jump instruction such as JMP(004) may be executed within a FOR-NEXT
loop, but do not jump beyond the FOR-NEXT loop.
The following instructions cannot be used within FOR-NEXT loops:
• Block programming instructions
• MULTIPLE JUMP and JUMP END: JMP(515) and JME(516)
• STEP DEFINE and STEP START: STEP(008)/SNXT(009)
Note If a loop repeats in one cycle and a differentiated bit is used in the FOR-NEXT
loop, that bit will be always ON or always OFF within that loop.
In the following example, the looped program section transfers the content of
D00100 to the address indicated in D00200 and then increments the content
of D00200 by 1.
Repeated 3 times.
&3
Programmed in a FOR-NEXT loop to cancel the execution of the loop for a
given execution condition. The remaining instructions in the loop are pro-
cessed as NOP(000) instructions.
