Hi,
agree with your suggestion!
Although we have to be careful to not mix it up with specific implementations
of datatypes in some drivers.

Hi all,
today I was at a customer’s site and used the Modbus driver to get data.
This generally worked fine.
The thing however I found a little complicated, was that the PLC seemed to
offer all values as 32Bit Floating point values.
So in order to correctly read them, I had to read an array of two
consecutive shorts and then manually convert them into a float.
I bet we can do this better.
So I thought … how about we use the same
https://en.wikipedia.org/wiki/IEC_61131-3 datatypes we are already using in
other drivers and for example if you write:
holding-register:1:REAL
it would automatically use modbus to read an array of two shorts and to
internally convert these to one REAL/float.
What do you think? I think we could probably do this in most drivers.
