Function
•
If the startup condition of JMP n switches on, the control jumps the program from this instruction to the LBL n of the same
code number. Always use JMP n and LBL n in pairs.
•
If the startup condition is not established, the next instruction will be executed.
•
To set this instruction in conjunction with other instructions in the same arithmetic-operation box, insert this instruction at
the end of the box.
•
The JMP n instruction is valid only within the same scan program. (A jump to a subroutine or interrupt scan cannot be
performed from a normal scan, nor vice versa.)
•
Nesting of JMP n instructions is possible, but note so that an overload error does not occur.
Notes
•
This instruction is checked prior to the execution, and if there is an error, the following error codes are set in the special
internal outputs R7F3 and WRF015. In this case, jump is not performed and the next instruction will be executed.

There is no LBL n.
H0040
A jump is attempted to a different program area.

Program
•
When the startup condition turns on, it jumps to LBL n.
•
If there is a timer within the program it jumped to, the progress value is updated,
but since instructions are not executed, output will not be turned on even if the
ON conditions are met.
