Value does not match between Mag6000 and PLC.

On your screenshots, is this a Modbus simulator?

Which PLC are you using?

 Yes! Modbus scanner.

M241 Schneider PLC.

I'm sorry, I don't know Schneider PLC.

I don't how the Schneider PLC make the addressing. You must read it in your PLC as a double float.

And this is a forum for Siemens, not for Schneider.

Have seen the data types of the registers?

There are float (4 Bytes) and double (8 Bytes).

Adressing of the registers have 2 Bytes. The addressing is wordwise, not bytewise as in Step 7.

You can not look at the regiters individually.
Example Register 3015, Totalizer 1 (m3).
The value Totalizer 1 (m3) is a double type, 8 bytes.
You must consider registers 3015, 3016, 3017, and 3018 as one value, not the individual registers.
This is also the reason why the next value (8 Totalizer 2 / Batch (m3)) starts in register 3019.

 Registers 3015, 3016, 3017, and 3018 as one value.

I know .

Can you tell me about Combine to get the correct value. 64bit

 Sorry! MAG6000 is Siemens?

Thank.

MAG600 is Siemens, that's right.

But not Schneider PLC is not Siemens PLC.

What you have to make to read a 8 byte value as one value in the Schneider PLC, that's for Schneider Forum.

I can make to read a 8 byte value as one value in the Schneider PLC!

but the value different. 

Therefore I want to know the pattern modbus for mag6000 only.

 thank you.

What data type ist the 8 Byte value? LINT?

that's no the same as double float.

 LREAL!

That's sounds good.

Have you try read as address 3014? In your screenshot we can see, Modbus address is Modbusregister minus 1 (3015 - 1 = 3014).
