CHAPTER 4: INTERFACES
Place an OR gate in the Logic Designer diagram. Only one action needs to occur. Any function input on the left side
satisfies the condition.
The number of inputs is configurable from two to 16.
Place an AND gate in the Logic Designer diagram. Multiple actions need to occur. All functions input on the left side are
required to satisfy the condition.
The number of inputs is configurable from two to 16.
Place a NOR gate in the Logic Designer diagram. Gives the value of one when all input operands have a value of zero
and otherwise gives a value of zero. It gives an output signal when there are no input signals. An inverter that reverses
the logic state.
The number of inputs is configurable from two to 16.
Place a NAND gate in the Logic Designer diagram. Gives the value of zero when all input operands have a value of one
and otherwise gives a value of one. It gives an output signal until all signals are present on its inputs. An inverter that
reverses the logic state.
The number of inputs is configurable from two to 16.
Place a XOR gate in the Logic Designer diagram, which is two exclusive OR gates. Only one action needs to occur. If
there are two inputs or there is no input, there is no output.
Place a NOT gate in the Logic Designer diagram. Gives the value of one when the input operand has a value of zero and
otherwise gives a value of zero. It gives an output signal when there is no input signal. An inverter that reverses the
logic state.
Place a latch in the Logic Designer diagram. A latch has two inputs and one output. One input is the Set input, and
other input is the Reset input.
Place a positive one shot symbol that responds to a positive going edge in the Logic Designer diagram. A "one shot" is a
single input gate that generates a pulse ins response to an edge on the input.
Place a negative one shot symbol that responds to a negative going edge in the Logic Designer diagram
Place a positive one shot and a negative one shot symbol in the Logic Designer diagram
Place a timer in the Logic Designer diagram
Elements
These blocks configure properties of the element or use element operands as input to FlexLogic equations.
