Description
E16
Specify logic equations of the form En =
<Operand><Operator><Operand>using the
following:0123456789=Digit() = Parenthesis! = NOT operation.
= AND operation^ = EXCLUSIVE OR operationE(followed by a
digit) = Equation numberF (Followed by a digit) = Function Key
numberI(Followed by a digit) = Binary Input numberL(Followed
by a digit) = LED numberO(Followed by a digit) = output relay
numberV(Followed by a digit) =Virtual Input/Output
number.ExamplesMake a function key LED toggle when
function key is pressed (requires E1 to drive L11 in output
matrix)E1 = F3^L11
