Example 1:
If you want, from TCP network, write a data it the RTU
network on the device at:
Address 5;
Through Gateway WORD 100 (Address RTU);
Address TCP 1000.
In the above scenario:
Specify the type of data between:
Coil Status (bit in read write);
Input Status (bit in read);
Holding Register (word in read and write);
Input Register (word in read).
From the side of the MODBUS TCP:
Address of data to read.
From the side of the MODBUS RTU:
Address of the device to interrogate;
Address of data to read on device.
Note:
If the RTU slave responds with an exception, that exception code will be transmitted to the TCP Master. If the RTU slave does not
respond within the estimated time defined by the Timeout parameter, an exception response will be given on TCP side: error code $0B.
