High−level Instructions
Description
The F19 (SJP) instruction skips the program between the F19 (SJP) and the LBL with the number specified
by S when the trigger turns on.
Program execution continues from the next instruction after the jump destination label.
Up to 256 jump destinations can be specified (the range of values in which S can be stored is from K0 to
K255).
LBL instructions are specified as destinations of JP, LOOP and F19 (SJP) instructions. Any instruction may
be used as the starting point for the jump destination.
Two or more LBL instructions with the same number cannot be used in the same program.
If there is no label with the same number as the value of S, or if the value stored is outside of the range, the F19
(SJP) instruction will not be executed.
Flag conditions
・Error flag (R9007):
・Error flag (R9008):
Precautions during programming
If the label is written to an address prior to the F19 (SJP) instruction, be aware that there is a possibility that the
scan cannot be completed, and an operation bottleneck error will occur.
The F19 (SJP) instruction cannot be used in a stepladder area (the range from SSTP to CSTP), in a
subroutine, or in an interrupt program.
A jump cannot be made from a main program to a sub−program (subroutines or interrupt programs written
subsequent to the ED instruction).
Using differential type instructions between F19 (SJP) and LBL instructions
This is the same as when programming is done between the JP and LBL instructions. Refer to the
explanation of the JP and LBL instructions.
You must be careful when using one of the instructions below, which are executed by detecting the leading
edge of execution condition (trigger) such as the differential instruction.
DF (leading edge differential)
Count input of CT (counter)
Count input of F118 (up/down counter)
Shift input of SR (shift register)
Shift input of F119 (left/right shift register)
NSTP (next step)
Differential execution type high−level instruction (this instruction is specified by P and a number)

Turns on and stays on when:
Turns on for an instant when:
− The content of S is smaller than K0.
− The content of S is larger than K255.
