Is it possible to configure a Digi One IA to convert modbus TCP(Slave) to modbus RTU(Master)? I have successfully configure the One IA to convert modbus RTU(Slave) to modbus TCP(Master) but not the other way around. Any help would be greatly appreciated.

I want to do the same configuration, but it does not work.  
Can you explain me how do you configure Digi one IA ?
