7.4 Structure Creation Instructions
Processing details
• After the FOR to NEXT instruction loop is executed unconditionally (n) times, the step following the NEXT instruction is
executed.
• Specify a value 1 to 32767 for (n). If a value -32768 to 0 is specified, the processing is performed regarding (n) as 1.
• To not to execute the FOR to NEXT instruction loop, use the CJ or SCJ instruction to jump the instruction loop.
• Up to 16 FOR instructions can be nested.
Operation error
• To terminate the FOR to NEXT instruction loop being executed, use the BREAK instruction.
• To perform pulse operations of an index-modified program within the FOR to NEXT instruction loop, use the
EGP or EGF instruction. Note, however, that no rising edge or falling edge instruction can be used on the
operation output side.
• The JMP instruction cannot be used to branch into the FOR to NEXT instruction loop from the outside.
• To create an easy-to-understand program, use a pair of instructions, the FOR and NEXT instructions, within
a single program block.
Error code
(SD0)
Description
3340H

The STOP instruction is provided within the FOR to NEXT instruction loop.
3341H
The NEXT instruction is executed before the FOR instruction.
3361H
More than 16 FOR instructions are nested. (The 17th instruction is executed.)
