Function
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.

The operation of CJPN(511) is almost identical to
JMP(004).
When the execution condition for CJP(004) is OFF,
program execution jumps directly to the first
JME(005) in the program with the same jump
number. CJPN(511) and JME(005) are used in
pairs.

Indicates the destination of a jump instruction.
When the execution condition for JMP0(515) is OFF,
all instructions from JMP0(515) to the next
JME0(516) in the program are processed as
NOP(000). Use JMP0(515) and JME0(516) in pairs.
There is no limit on the number of pairs that can be
used in the program.
