4.7 Advanced Math Parameters Set Up Group
Introduction
This data deals with various Logic Gates that are available for use in the
controller. It also lists what each of the two inputs and the output can
represent. Up to five different gates can be configured.

LOGIC GATE FUNCTION -
DISABLE - disable the logic gate function.
ENABLE - allows the Logic Gate function and the
prompts for this option to be shown.
For each gate used, make a selection for:
Gate Type GATEnTYPE
Input A Source GATEn INA
Input B Source GATEn INB
Output Use GATEn OUT
(n) = 1,2,3,4,or 5
GATE(n) TYPE
(n = 1, 2, 3, 4, or 5)
GATE TYPE - In digital logic, there are only two
states that can be present:
"0" - OFF, or "1" - ON
Listed are definitions of the gates available and their
truth table which indicate what happens to the
Output with regard to the state of the Inputs.
NOT USED
NOT USED - No Selection
OR
OR - With this gate, if Input A OR Input B are ON,
then the Output will be ON. Also, if both Inputs are
ON, the Output will also be ON because it takes any
one Input being ON
to make the Output

NOR
NOR - The NOR gate is similar to the OR gate,
except that the Output is inverted. It is exactly
opposite of the OR gate and is referred to as NOT
OR or NOR.
If Input A or Input B are ON
, the Output is OFF.
