Modbus : converting data from two registers into float

[bigmanvstrashman]

Hi,

Wish you happy new year to team and users !

I have some dificulties to convert the modbus data from a device (here a mass flow).

I retrieve the data, but i need to convert it.
Here the configuration :

• Reading holding register (3)
• quantity : 2 (u16)

I need a 32-bit float (SGL) after the conversion.
I tried different configuration but without success.
May be need some Swap before join ?

Thanks for your help

Emmanuel.

Hi Emmanuel,

thanks for your question. Can you share configuration of Modbus in your project (or preferably whole REXYGEN project if possible) so I can have a look at the settings you used?

There is possibility to Swap Bytes or Swap Words at each Modbus item - did you try that?

Regards, Tomas

PS : later, cause a collegue take my device...
