In some applications you may need to use assorted math instructions in your PLC program. In the programming environment, in the "basic instructions" section, there is a folder named "math functions". If you open this folder, you'll see a full list of math functions there. In this and the next lessons, I'm going to briefly introduce you to these instructions and then you're going to learn how to use them in PLC programs using some practical programming examples.
In this new video you are going to learn how the "negative" and the "absolute value" instructions work.
I have 3 other useful instructions or Functions in the math functions folder named MIN, MAX and LIMIT. The names should be self explanatory. The appearance of these functions is different from the other instructions in this folder because they're considered as FCs, and you may be familiar with th...
