hi everyone!
I have a problem when I use RSLogix5000 to read value from PowerFlex 700s by datalink.

The returned value is not same with the value on PowerFlex 700s.

Any ideas to solve it?
I can't understand this returned value. For example when I read "Speed ref 1" = 17, the returned value is 67633152, sometime the returned value is the internal value of PowerFlex 700s, I can't understand this value too.
Can you explain this value? And how to get true value?

when I enter the speed from the drive down software Rslogix5000 powerflex700s: I enter 100rpm to control the motor speed feedback value from encoder0 do not understand me, with value = 101.6268, internal value = 1033015891
please explain to me these values ​​and how to calculate these values​​.
thanks you so much!
