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. Chris
