[?]: problem with DataLink in DeviceNet

[hoanglong777]

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?

Regards,

Hoang!

it’s 16Bits or 32Bits datalink?
in some cases you need to separate the 32bits word in 2x16Bits to read the correct values
and if this datalink is a floating point (real) value, you need to put this DINT (32) in a Real word

Thank you Vash! But 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?

Thank you so much!
