When the execution condition for the first IL(02) is OFF, TIM 511 will be reset to
1.5 s, CNT 001 will not be changed, and 00502 will be turned OFF. When the
execution condition for the first IL(02) is ON and the execution condition for the
second IL(02) is OFF, TIM 511 will be executed according to the status of 00001,
CNT 001 will not be changed, and 00502 will be turned OFF. When the execution
conditions for both the IL(02) are ON, the program will execute as written.

Limitations Jump numbers 01 through 99 may be used only once in JMP(04) and once in
JME(05), i.e., each can be used to define one jump only. Jump number 00 can be
used as many times as desired.
Description JMP(04) is always used in conjunction with JME(05) to create jumps, i.e., to skip
from one point in a ladder diagram to another point. JMP(04) defines the point
from which the jump will be made; JME(05) defines the destination of the jump.
When the execution condition for JMP(04) in ON, no jump is made and the pro-
gram is executed consecutively as written. When the execution condition for
JMP(04) is OFF, a jump is made to the JME(05) with the same jump number and
the instruction following JME(05) is executed next.
If the jump number for JMP(04) is between 01 and 99, jumps, when made, will go
immediately to JME(05) with the same jump number without executing any
instructions in between. The status of timers, counters, bits used in OUT, bits
used in OUT NOT, and all other status bits controlled by the instructions between
JMP(04) and JMP(05) will not be changed. Each of these jump numbers can be
used to define only one jump. Because all of instructions between JMP(04) and
JME(05) are skipped, jump numbers 01 through 99 can be used to reduce cycle
time.
