Explanations:
1. FOR and NEXT instructions are used when loops are needed. No contact to drive the
instruction is required.
2. “N” (number of times loop is repeated) may be within the range of K1 to K32767. If the range
N≦K1, N is regarded as K1.
3. An error will occur in the following conditions:
• NEXT instruction is before FOR instruction.
• FOR instruction exists but NEXT instruction does not exist..
• There is a NEXT instruction after the FEND or END instruction.
• Number of FOR instructions differs from that of NEXT instructinos.
4. FOR~NEXT loops can be nested for maximum five levels. Be careful that if there are too many
loops, the increased PLC scan time may cause timeout of watchdog timer and error. Users
can use WDT instruction to modify this problem.
