JMPI
[Function] This command is used to instruct a program to jump to a step with a specified
tag number when the input conditions of a general purpose input signal meet
the set conditions in the program.
[Explanation]

The jump is executed only when the input of ports set by this command
satisfy the ON/OFF conditions of general input port; if they do not, the
program proceeds to the next step.

If the JMPI command is set as shown below, when the general-purpose
input port 1 No. 1 (general-purpose input port 1-1) and No. 7
(general-purpose input port 1-7) are ON and the general-purpose input port
1 No. 4 (general-purpose input port 1-4) and No. 5 (general-purpose input
port 1-5) are OFF for the unit of which the station No. is set to "0", the
program will jump to the designated step. The general-purpose input signal
at the "•" display section will not judge the conditions.
(Example)
[Key operation]
STEP 1
Press
JMP
5
twice.
NOP changes to JMPI.
Press
ENT
.
STEP 2
Use the numeric keypad to enter the tag No. the
program jumps to, then press
NEXT
.
(Input range: 1 to 999.)
STEP 3
Use the numeric keypad to enter a station No.,
and press
ENT
.
STEP 4
Use the numeric keypad to enter a port No.,
and press
ENT
.
NOTE

The tag No. for STEP 2 can be set to "0" as a temporary value. However, if the
command is executed with that value, the "NO TAG FOUND" error will occur.

When using multitasking, a tag No. in another task cannot be jumped to.
