Hi all,

I am having some issues with modbus values.

I am using a Floboss 107 as a Modbus Master, polling data from a SLC 5/04 that has prosoft 3150-MCM module (slave).

We can get the writes to work, however the is a block that the FB107 needs to read back from the prosoft. We get data, but it is not coming in right.

The Prosoft card is in integer format, and the FB107 wants the data converted to floating point format.

We are trying every possible conversion code for the FB107, still no luck.

Is there a little known secret for interfacing these two together? I have done many FB107's in modbus environments, interfacing to different PLC's, RTU's and HMI's with little to no issue.

Any help is appreciated.

Thanks,
K
