How to write data to floboss 407

Hello everybody. This forum helped me many times, is the first time I make a post here. My problem:

I have a floboss 407 (Link to download backup file at the end), I need to read and write ( change) the value of the "Orifice Diameter" for meter #4: 17-31, using modbus (RS-485).
I have a PLC "ControlLogix: 1756-L55 revision: 11.25" with: MVI56-MCM Prosoft communicating to FloBoss 407. Communication is OK.

Rocklink file:
In function 3A line 5: Configuration to read: "Orifice Diameter" working OK

I know that to write data I have to configure function 16A, but I do not understand how.

Here is a link to a Roclink 800 file I did in the past and the 407 Hardware Manual.
Have a look at the Modbus function Com 1 Function 16A

Or the Comm 2 Function 16a

And you'll need this link to the Protocol manual

Hope this helps.

This is a link to the Modbus map for that project.
This may help make sense.

what I recall is that this site had the Roc connected to a GE Fanuc PLC. The PLC was a modbus slave only.(Couldn't Master)

The Roc acts as a gateway for the Scada Systen to read and write the PLC (Very few writes if i recall)

Good Luck
