Open your Modbus Poll, go to Display > Key , and start mapping one critical register today. Once you see your live data labeled correctly, you will never work "raw" again. Do you have a specific Modbus Poll version or a tricky 32-bit register? Leave your questions below!

0, System_Voltage, U16, 0.01, VDC 2, Motor_Current, S16, 0.1, Amps 10, Power_Factor, Float, 0.001, Ratio One of the most powerful features is decoding status words. If register 100 contains alarm bits, you can split it:

If you have ever scrolled through hundreds of raw register values looking for a specific temperature or pressure reading, you know the pain. The Register Key is your solution. In simple terms, a Register Key (often found under Display > Communication... or as a .key file) is a translation table. It converts raw, anonymous register numbers into human-readable engineering values with proper labels, scales, and units.

In the world of industrial automation, Modbus Poll is a legendary tool. It is the "Swiss Army knife" for engineers testing and troubleshooting Modbus RTU or TCP networks. While the software interface appears simple—a grid of addresses and values—the true power of efficient data analysis lies in one often-overlooked feature: The Register Key .
