MILH
517
CS/CJ
-series CPU
Unit Ver. 2.0 or later
and CJ2 CPU Units
only
When the execution condition for MILH(517) is OFF, the outputs for all
instructions between that MILH(517) instruction and the next
MILC(519) instruction are interlocked. MILH(517) and MILC(519) are
used as a pair.
MILH(517)/MILC(519) interlocks can be nested (e.g., MILH(517)—
MILH(517)—MILC(519)—MILC(519)).
If there is a differentiated instruction (DIFU, DIFD, or instruction with a
@ or% prefix) between MILH(517) and the corresponding MILC(519),
that instruction will be executed after the interlock is cleared if the dif-
ferentiation condition of the instruction was established while it was
interlocked.

CS/CJ
-series CPU
Unit Ver. 2.0 or later
and CJ2 CPU Units
only
When the execution condition for MILR(518) is OFF, the outputs for all
instructions between that MILR(518) instruction and the next
MILC(519) instruction are interlocked. MILR(518) and MILC(519) are
used as a pair.
MILR(518)/MILC(519) interlocks can be nested (e.g., MILR(518)—
MILR(518)—MILC(519)—MILC(519)).
If there is a differentiated instruction (DIFU, DIFD, or instruction with a
@ or % prefix) between MILR(518) and the corresponding MILC(519),
that instruction will not be executed after the interlock is cleared even if
the differentiation condition of the instruction was established.

MILC
519
CS/CJ
-series CPU
Unit Ver. 2.0 or later
and CJ2 CPU Units
only
Clears an interlock started by an MILH(517) or MILR(518) with the
same interlock number.
All outputs between MILH(517)/MILR(518) and the corresponding
MILC(519) with the same interlock number are interlocked when the
execution condition for MILH(517)/MILR(518) is OFF.

N: Jump number
When the execution condition for JMP(004) is OFF, program
execution jumps directly to the first JME(005) in the program with
the same jump number. JMP(004) and JME(005) are used in pairs.

N: Jump number
The operation of CJP(510) is the basically the opposite of JMP(004).
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. CJP(510) and JME(005) are used in pairs.
