Therefore, we found that it is crucial to go through all logic gates and do simulations for them all in this tutorial. For example, using XOR logic is very common for comparing two inputs to decide if they are equal or different.
Using this variety of logic gates, enrich the logic and fluency of writing the logic in different situations. So, it is very beneficial to know shortcuts for writing ladder logic simpler, more readable, and easier for others to develop. Working in ladder logic programs is getting further complicated especially for large-scale projects. So why do we need to go learning other logic gates when we can implement them by using that three basic logic gates. On the other hand, someone may say, oh we can do XOR by using the basic three gates of “AND”, “OR”, and “NOT”. For example, we have shown in the logic gates article that, XOR can be used to compare two inputs and check if they are equal or not. However, because the logic of large-scale projects is getting more and more complicating, a lot of time we have to use the other functions to do tasks faster. We have started and gone through simulating the basic logic gates which are “AND”, “OR”, and “NOT” as they are the most important basic logic gates by which we can form other logic gates. Today we are going to resume the simulation of logic gates. In an earlier part, we already have gone through the very basic logic gates of “AND”. Hello friends! I hope you are all very well! I am so happy to meet you today to continue learning and practicing PLC ladder logic programming.
