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 these types of programming blocks. In this lesson you're going to learn how these functions work and what you should watch for when using them in your PLC program.
There are some other instructions in the math functions folder which you can use for specific mathematical operations like square SQR or square root SQRT. Let's find out how these actually work.
There are different applications across various industries where you need to measure and control the temperature of different factory sections. In this and then next lessons, you're going to learn how to write a PLC program using the math functions to measure a gas turbine gear box temperature an...
In the previous lesson, you learned that how the small portion of the alarm system for a gas turbine works. As I indicated, in this lesson I'm going to start writing a PLC program that will activate the alarms whenever the temperature measured by each sensor is out of range.
