Implementing Logic Functions Using Only NAND or NOR Gates ... Why use only NAND gates or only NOR gates? So, why would a lecturer request that his students implement a logic function using only NAND gates or only NOR gates (note that I specifically didn’t say "only NAND or NOR gates," because this could be construed to mean that you can use both NANDs and NORs, but not ANDs and ORs etc.) The Decision Makers: AND, OR and NOT | PLCdev The ladder logic equivalent for an AND function looks like two normal contacts side by side. The OR function. Last but not least the OR gate is associated with the following symbol that also can have any number of inputs but only one output.

Circuit Diagrams versus Logic Diagrams | Physics Forums You can study the electronics involved in a logic diagram but generally it is not of any interest, else you would have started with a circuit diagram. Generally, when you draw a logic diagram with things like NAND gates you really don't care what the implementation methodology is, you just care about the logic. Ladder Logic Tutorial Part 2: Building Logic PLC Academy NOT Logic Gate with Ladder Logic. There is still one logic relationship left between the conditions above. For the motor to be active the stop button has to not be pressed. For this we will use the NOT logic. NOT logic or negation can be implemented with a negated contact either in the ladder logic or as a negated physical contact.
