Alvaro del Castillo commented on PLC4X-45:
------------------------------------------
[~niclas] I totally agree with you that we must identify the different formats
that vendors have introduced for floating points in their products and add
support for them. But probably we should do it after the modbus driver
refactoring to adopt [MSpec
approach|https://plc4x.apache.org/developers/code-gen/protocol/mspec.html].
[~cdutz] is discussing the float modelling in the [mailing
list|https://mail-archives.apache.org/mod_mbox/plc4x-dev/201912.mbox/browser].
IMHO I would continue this discussion in the mailing list trying to find the
most important floating points formats used in the industry in order to support
them.
As a reference, in
[libmodbus|https://github.com/stephane/libmodbus/blob/master/src/modbus-data.c#L121]
they have added some of this formats already and we can follow them.
> [Modbus] Make the modbus driver support reading and writing of all or at

> Currently it seems as if the Modbus driver only supports reading BOOLEAN,
