How to configure the DIGI IA RealPort based on the below requirements?

Dear Support,

Please, be informed that we have some DIGI with P# 70001862.
Each one is connected to 8 slave devices (RS-485/422, 4 wire), and on the Ethernet port it’s connected to SCADA system by Modbus TCP/IT.

Could you please send me the required configuration to success this communication.

Appreciate your prompt reply whereas we are in the commissioning stage.

Regards,
