Applied Instructions
First execute the instructions between FOR~NEXT instructions for several times
(the loop time is assigned by the source data), then execute the steps after NEXT.

z FOR、NEXT instructions must be programmed as a pair. Nesting is allowed, and the
nesting level is 8.
z Between FOR/NEXT, LDP、LDF instructions are effective for one time. Every time when
M0 turns from OFF to ON, and M1 turns from OFF to ON, [A] loop is executed 6 times.
z Every time if M0 turns from OFF to ON and M3 is ON, [B] loop is executed 5×7=35
times.
z If there are many loop times, the scan cycle will be prolonged. Monitor timer error may
occur, please note this.
z If NEXT is before FOR, or no NEXT, or NEXT is behind FENG，END, or FOR and
NEXT number is not equal, an error will occur.
z Between FOR~NEXT, CJ nesting is not allowed, also in one STL, FOR~NEXT must be
programmed as a pair.
