Floating-point Math Instructions
Inputting the Instructions
The input comparison instructions are treated just like the LD, AND, and OR
instructions to control the execution of subsequent instructions.
Input type
LD
The instruction can be connected directly to the left bus bar.
AND
The instruction cannot be connected directly to the left bus bar.
OR
The instruction can be connected directly to the left bus bar.
LD connection
<F
AND connection
OR connection
<F
Options
With the three input types and six symbols, there are 18 different possible
combinations.
Symbol
=
(Equal)
< >
(Not equal)
<
(Less than)
<=
(Less than or equal)
>
(Greater than)
>=
(Greater than or equal)
