If there are two or more JME(005) instructions in a program for the same jump
number, the one at the lower address is valid and the ones at higher addresses
are ignored.
(221)
When the execution condition (CIO 000000) is ON, the program
CJP #0100
up to the JME(005) instruction with jump number 0100 is ignored.
(005)
JME #0100
(222)
When the execution condition (CIO 000001) is OFF, the program
CJPN #0101
up to the JME(005) instruction with jump number 0101 is ignored.
(005)
JME #0101
The jump number (N) must be BCD between 0000 and 0999.
ER (A50003):
Ladder Symbol
END(001) is required as the last instruction in any program. No instruction writ-
ten after END(001) will be executed. The END(001) instruction indicates the end
of the entire ladder program for that cycle.
If there is no END(001) in the program, no instructions will be executed and the
error message "NO END INST" will appear.
END(001) turns OFF the ER, CY, GR, EQ, LE, and N Flags.

NOP
NOP(000) is not generally required in programming. When NOP(000) is found in
a program, nothing is executed and the program execution moves to the next
instruction. When memory is cleared prior to programming, NOP(000) is written
at all addresses.
NOP(000) can only be used with mnemonic display, and not with ladder pro-
grams.
NOP(000) can be inserted in a program at the position where an instruction is to
be inserted later. Then when the instruction is inserted there will be no gap in the
addresses.
There are no flags affected by NOP(000).
Content of *DM word is not BCD when set for BCD.
Jump number is not BCD or not between 0000 and 0999.
CJP(221) or CJPN(222) in program without a corresponding
JME(005). Also turns ON the Jump Error Flag A40213.
