32.4.1.2 Explanation of the NO Instruction
-
Use a NO instruction to determine the ON or OFF
state. The instruction can be used to determine the ON or OFF state
of an external input or an internal coil.
-
You cannot use a NO instruction without including
another instruction just to the left of the right power bar. The
other instruction can be an output instruction or any instruction
other than an input.

NO instruction closes the contact.

When the bit variable (Start) turns OFF, the
NO instruction opens the contact.
