HELLO
so i have dvp201lc-sl
i wanna read the value using advancedHMI
there is a software named LCsoft for it
and it can read it online
as in the attachments
i wanna read the ( CH1 Weight Value )
but i can`t get the address for it to use with modbus ascii
can some one help me ?
with thanks

I looked through the manuals, but did not see anything about the Modbus addresses. I would start with the most common 40001
You could also use a serial port sniffer software to capture the data from LCSoft to see if it is using Modbus.

Try this:
- Add a ListBox to the form
- Add a button to the form
- Double click the button
- Add this code
Dim v() As String = ModbusASCIICom1.Read("40001", 50)
For i = 0 To v.Length - 1
ListBox1.Items.Add(i & " : " & v(i))
Next
- Run the app and click the button
See if any of those values are what you need.

so i found the register
but for some reason there is a bit of diffrence in the value
you can see in the video
https://drive.google.com/file/d/17kS12IumcwqEjkdUTpbioauRn_LOVvhm/view?usp=sharing
it looks like nothing
but in this case the value will be much higher
so the diffrence will grow bigger
any idea why?
or how i can fix it ?
but i wanna try the code you sent too
i will tell you the results

the code didn`t work

Is the value really different? Because of it fluctuating, it is hard to tell.
In your BasicLabel, set ValueScaleFactor to 0.01

Reduce the value of 50 to 10. Maybe there are not 50 registers in the device

All Delta related products Holding register address starts at 4096 .
If master is 1 based , it would be 4097 .
In modscan its first Modbus address is seen as 44097 or 404097 , if in six digits format.
Good Luck.
