Function

• Subtracts 1 from the number of times repeated (s) for the FORn (s) instruction of the same code number, then jumps to FORn (s).

Notes

• This instruction is checked prior to execution, and when there is an error, the following error code is set in the special internal output WRF001. Also, the CPU error code '34' is set to special internal output WRF000.

CPU error code	Special internal output	Error code	Error description
34	WRF001	H0003	Duplicate definition of NEXT

• If an error is generated during the execution of the instruction, an error code will be set in the special internal outputs R7F3 and WRF015, and the following program will be executed.

Special internal output		Error code	Error description
R7F3=1	WRF015	H0016	FOR undefined

		H0046	FOR nesting overflow

•When R000 is turned on, the progress value (TC n) of the timer or counter is cleared with 0 for 512 points.

•Once the FOR to NEXT starts, the instruction keeps executing until (s) is “0.”

•FOR0 (WR0000) performs instructions after TC0 (WR0001) = 0 while WR0000>0, subtracts “1” from WR0000 at NEXT0, then jumps to FOR0 (WR0000).

•FOR0 (WR0000) jumps to the next instruction within the current box upon WR0000 = 0.
