Modbus TCP/IP Client to/from RTU/ASCII Master 

In this mode of operation, the TCP/IP Client device and RTU/ASCII Master device essentially 
share the same data values. Up to 5 Modbus TCP/IP Clients can talk with the router at a given 
time. In this mode, the data table for the Input Coils and Coil Status are overlapping, just like 
the data table for the Input Registers and Holding Registers. This means that a read request 
(Function Code 0x02) of Input Status 10 will return the same value as a read request (Function 
Code 0x01) of Coil Status 10 would return.
