5.7 Common Items in Sequence Control Instructions
This paragraph describes basic instructions (such as LD and AND) and application instructions
in sequence control.
These instructions are used together with positioning control instructions, and control auxiliary
units accompanied by positioning.
5.7.1 Difference in operation by PLC
The difference from arithmetic operation in the PLC is that sequence con-
trol instructions are step type, so do not perform cyclic arithmetic opera-
tion.
For example, in the program shown on the right, if X00 is OFF when the
line N100 is executed, Y00 is not output.
When cyclic arithmetic operation is required, use jump instructions
described later. (Refer to Paragraph 5.10.)
Contact instructions have nothing to do with positioning control instruc-
tions (cod instructions). In the program shown on the right, cod00 in the
line N201 is executed without regard to the ON/OFF status of X00 in the line N200.
