Problem accessing float data through MODBUS

[Nishant]

Dear All,

                 I am taking the data through the MODBUS in LabVIEW, but this time the data are floating point containing four bytes and having the decimal values, but the problem is values after decimal are truncated and it indicator doesn't shows it? so what could be the problem? is it  a problem of MODBUS with float data or it is a problem of LabVIEW indicators? what changes are required by me to show  the correct data?

Hope for the positive reply.

Thanks in advance,

Nishant

hi there

please post some code

Modbus only lets you read/write 16 bit register values. It is up to the labview program to convert the values into flating point. see this thread.

Hi there,

If you are reading floating type data, the appropriate conversion is required to get single value from four bytes.

Hope this would help.
