An Example of how to interpret the Representation of Large Numbers in Modbus

Modbus inherently does cannot represent numbers larger than 65535. So over the years vendors had to create ways around this through the use of multiple memory locations. In this video, I show you one such example and how to interpret the data.

Great video, helped me understand why I was seeing weird numbers on my client end!

[@EmileAckbarali]

Really glad to hear it helped!

This video helped me to accomplish my first modbus project of reading energy meter data. I have also purchased your udemy course. Thank you.

[@EmileAckbarali]

Wow, that's so great to hear Rahul. Congratulations on successfully completing your first Modbus project!

Great Explanation.Keep it going...Thumbs Up

[@EmileAckbarali]

Thanks very much!

In a RedLion HMI using Crimson 3.1 software we would use the R64 function to do this extended math on a 64bit floating point number. Great Video!

Thanks for the info!

Hi sir, Im trying to read some energy parameters from schneider EM6400NG+ meter through KepserverEx6. And its also showing some exponential value in quick client view. The quality is showing good for all parameters. Tag address corresponding to particular padam ethra given as per data sheet provided by schneider. When I tried with modscan, the meter gives the exact data when we changed the data type to swapped float. But in data sheet the address is provided for float-32. How can we resolve it sir.

[@thetenderloins6564]

what would be a solution incase I had to write a 32 bit data?

Hello I have read data from circutor CvmC4 meter (which data types is float) but can read data which data type is long and int
I'm using modscan

[@EmileAckbarali]

Floating point is represented in a completely different way than integers in Modbus.

[@travellers9170]

how can i read int and log data type of modbus?

Why u didn't multiply the "LSW" with 65536?

[@nayrbsworld3048]

Sir is this in rs485 in dojo? and floating numbers also?

[@EmileAckbarali]

Sorry no, this was done separately based on additional student questions.

[@miguelnajera3979]

Hello, how will you read this register? Register 39681?? does it contairs

[@EmileAckbarali]

I am not sure I understand the question. Could you give more detail please.
