You became familiar with integer and double integer data types in the previous lesson. In this lesson you're going to become familiar with the rest of data types in comparator operations including real, byte, word, double word and time.
Before starting with practical PLC programming examples for comparator operations, I'd like to discuss a few practical points on how to use these instructions in your PLC program.
In the previous lessons, in the section about counters, I wrote a PLC program to run a conveyor belt and count the number of products entering the factory warehouse. In this lesson, I'm going to develop that PLC program using the comparator operations in a way such that when the number of product...
In some cases, although you select the correct data type for the comparator operations, you'll see that there are still errors in the software.
when you enter a variable for comparator instructions and you see that, despite considering all the parameters you'll constantly get an error, you nee...
