RTU 5/03 from Allen B.

Hello everyone. I was going through an old project, that needs comissioning soon, and I stumbled upon its PLC model. It's an AB SLC RTU 5/03 with modbus slave model. I had fiddled with the prosoft modbus model and know how to write that logic out. So I was wondering if the way of writing a Send and Receive logic the same as the prosoft model.
If i have to read an address #300101.0 to #300101.15 to the RTU 5/03, do I move it to N7 or N10?

Can anyone direct me?
Thanks a lot!

regards

Well, I had forgotten about the attachment of the ladder logic I did for the prosoft model. But I was wondering if the same can be applied to the SLC 5/03 with modbus slave.
So is there anyone who can help me?
