The MODBUS plug-ins already support 16 bit integer values. The width
of them depends - conform to the MODBUS specification - on the chosen
IO mode. This mode influences if the data are 8 bit int, 16 bit int or
32 bit float.
In case you need something additional that is outside of the scope of
the MODBUS specification you can add this easily, the sources are open
and available at
Alternatively you can let us do this modification as soon as we have
some time for it. In this case we'd need detailed information which IO
mode you're using, how many bytes have to be concatenated and which
byte order they have.

I have a low cost modbus controller connected to my Windows 7 PC via serial
USB. Most software platforms that support modbus allow some modification of
the type of data that is expected back from the modbus device: floating
point vs 16 bit integer at a minimum. My device only supports 16 bit
integer as many low cost modbus devices do.
Is there a way to specify or adjust for this with the Modbus control?
Thanks in advance.
