ModBus Float inverse format

Hello IPS freinds,

Does anyone knows how to convert the „float inverse“ to something readable for IPS.

My modbus transmitter provides the Float but the modbus instance in IPS does not support this format.

Anyone?

Try turning on the „Flip MSW/LSW“ option in the ModBus Gateway. That should help.

Thx Paresy,

I already tried that and it is necessary to flip it. but witch format do i have to choose in IPS.

Modbus delivers Float inverse --> we flip LSW and MSW so we have a normal Float.

But due to PHP 5.3 we only have 31 bits to evaluate, and there i am lost

Maybe the anhange make somethings clear !!

Real -> That is a 4 Byte floating value.

Hello,

I have switched off the wordswap and selected readonly! and now it is working fine, the question is why?

Is there a way to see the code in the modbus instance
