NOT
NOT(010) reverses the execution condition.
NOT(010) is an intermediate instruction that inverts the execution condition that
precedes it. As an intermediate instruction, it cannot be placed at the end of an
instruction line, only between conditions or between a condition and a right-hand
instruction.
NOT(010) cannot be used as right-hand instructions, i.e., another instruction
must appear between them and the right bus bar.
There are no flags affected by NOT(010).
The following example and bit status table show the operation of NOT(010).

When instructions are combined into blocks that cannot be logically combined
using only OR and AND operations, AND LD and OR LD are used. Whereas
AND and OR operations logically combine a bit status and an execution condi-
tion, AND LD and OR LD logically combine two execution conditions, the current
one and the last unused one.
AND LD and OR LD are not necessary when drawing ladder diagrams or when
inputting ladder diagrams using ladder diagram programming. They are re-
quired, however, to convert the program to and input it in mnemonic form.
In order to reduce the number of programming instructions required, a basic un-
derstanding of logic block instructions is required. For an introduction to logic
blocks, refer to 4-4-1 Logic Block Instructions.
There are no flags affected by these instructions.
