How to transfer data between PLC and LabVIEW correctly?

Dear All,

I am new to LabVIEW and PLC, so don't judge too harshly.

I use Modbus/TCP server Data communication between Productivity 1000 PLC and PC.

Now, I can control the PCL through LabVIEW.

There is a small issue: How to transfer data between PLC and LabVIEW correctly?

I am using a holding register to store an analog input data (32 bit, float), it shows the correct number in the Productivity Suit software.

But when I read the holding register from LabVIEW, the number is not the actual number.

So I think this must be the data converting between the Productivity 1000 PLC and LabVIEW.

Anybody can help me out? Thanks a lot,
