How to Scale Analog Sensors in TIA Portal | NORM_X & SCALE_X Tutorial
In this video, we dive deep into Analog Sensor Scaling using Siemens TIA Portal. If you are working with S7-1200 or S7-1500 PLCs, understanding how to convert raw counts into real-world units (like Temperature, Pressure, or Level) is essential.
We break down the two most important instructions:
➡️NORM_X: How to normalize the raw input signal (0-27648) into a linear value between 0.0 and 1.0.
➡️SCALE_X: How to take that normalized value and scale it to your specific sensor range (e.g., 0-100°C).
What you will learn:
➡️Understanding the Siemens raw data range (0 to 27648).
➡️Configuring Analog Input (AI) modules in Hardware Configuration.
➡️Step-by-step logic implementation using NORM_X and SCALE_X.
➡️Handling 4-20mA and 0-10V signals.
➡️Testing the logic using PLCSim.
