Kepserver and Ac500 eco
Hey all
My plc is pm564- eth , i need to send all my analog input which already converted into real in my project to kepserver by modbus tcp , but it seem that kepserver dose not have the ( real type ) and my analog in real how can i send my data into real via modbus and what should my modbus address be ?
I mean if am using M area and i need to send Word it would be %RW0.0 = 40001
And if i convert my data to word i will lose the point Ex : 3.4
It would be 3
Any help ?

The answer by kstoilov for the question "Signal range of data type real" (https://forum-controlsystems.abb.com/10041303/Signal-range-of-data-type-real) is helpful here.
Modbus TCP can only pass over 16bit segments. So you would need to pass over the components of the analog input into split "words" or int data types then convert that back into the real value on Kepserver.
