c. Connect the RS232-to-USB adapter to the USB-A port on the
EMX.
Note: DO NOT connect the Modbus RTU device or Modbus bus to
the RS485 ports on the EMX, which is NOT supported.
2. On the EMX, enable and properly configure the Modbus Gateway
feature. See
Modbus Gateway Settings
(on page 125).
Communications between Modbus TCP and RTU devices:
The EMX acts only as a message gateway for the Modbus TCP
client.
Messages from the Modbus TCP client(s) are passed through the
EMX to the connected Modbus RTU devices or Modbus bus.
The Modbus RTU devices on the bus are identified with their
Modbus RTU addresses using the Modbus unit identifier addresses
in the Modbus TCP protocol.
If the Modbus TCP client does not support unit identifier addressing,
refer to
Modbus Gateway Settings
(on page 125).
The EMX supports communications to multiple Modbus RTU devices.
Note that the connected Modbus RTU devices are invisible to the
EMX.
Modbus Gateway Settings
1. Choose Device Settings > Network Services > Modbus Gateway.
2. Select the Enable Modbus Gateway checkbox.
