Instructions with a differen-
tiation option
Note (1) Block programs can be used in a step ladder program section.
(2) A block program can be used in an interlock section (between IL and ILC).
The block program section will not be executed when the interlock is ON.
(3) A block program section can be used between MULTIPLE JUMP (JMP0)
and MULTIPLE JUMP END (JME0).
(4) A JUMP instruction (JMP) and CONDITIONAL JUMP instruction
(CJP/CJPN) can be used in a block program section. JUMP (JMP) and
JUMP END (JME) instructions, as well as CONDITIONAL JUMP
(CJP/CJPN) and JUMP END (JME) instructions cannot be used in the
block program section unless they are used in pairs. The program will not
execute properly unless these instructions are paired.
CP-series programs can be checked at the following stages.
• Input check during CX-Programmer input and other operations
• Program check by CX-Programmer
• Instruction check during execution
• Fatal error check (program errors) during execution
The program will be automatically checked by the CX-Programmer at the fol-
lowing times.

During online editing
The results of checking are output to the text tab of the Output Window. Also,
the left bus bar of illegal program sections will be displayed in red in ladder
view.
