Sequence Control Instructions
Section 3-5
and CJPN(511) jumps to the first JME(005) when the execution condition is
OFF.
Because the jumped instructions are not executed, the cycle time is reduced
by the total execution time of the jumped instructions.
Operation of CJP(510)
When the execution condition for CJP(510) is OFF, no jump is made and the
program is executed consecutively as written.
When the execution condition for CJP(510) is ON, program execution jumps
directly to the first JME(005) in the program with the same jump number.
Operation of CJPN(511)
When the execution condition for CJPN(511) is ON, no jump is made and the
program is executed consecutively as written.
When the execution condition for CJPN(511) is OFF, program execution
jumps directly to the first JME(005) in the program with the same jump num-
ber.
Flags
The following table shows the flags affected by CJP(510) and CJPN(511).
Note
For CJ1M-CPU11 and CJ1M-CPU21 CPU Units, the jump number must be
between the range 0 to 255 (0000 to 00FF hex).
Precautions
All of the outputs (bits and words) in jumped instructions retain their previous
status. Operating timers (TIM,
TIMX(550), TIMH(015), TIMHX(551),
TMHH(540), and TMHHX(552)) continue timing be-cause the PVs are
updated even when the timer instruction is not being executed.
Instructions in this section are not
executed and output status is
maintained. The instruction execution
time for these instructions is eliminated.

ON if there is not a JME(005) with the same jump number
as CJP(510) or CJPN(511). (See note.)
ON if N is not within the specified range of 0000 to 03FF.
ON if there is a CJP(510) or CJPN(511) instruction in a
task without a JME(005) with the same jump number.
OFF in all other cases.
