Do you know how to scale your Analog input? Or control your Analog output?
Many people Struggle with Analog signals in PlC programming. How to use an analog input or output in your control algorithm for PLC can be tricky. Most often while you are reading PLCs you will see digital example PLC programs where you have to work with only two condition ON and OFF. But when you will work with analog signals you will see that an analog signal can take any value between its low and high value. So while working with analog signals you have dealt with infinity states.
