MESR424 Modbus Gateway Operational Connections
MESR424 Modbus Gateways can operate in Direct IP Mode.
Using MESR424 Modbus Gateways in Direct IP Mode
A Direct IP connection allows applications using TCP/IP socket programs to
communicate with the COM ports on the Modbus gateway. In this type of application the
Modbus gateway is configured as a TCP server. The socket program running on the PC
establishes a communication connection with the Modbus gateway. The data is sent
directly to and from the serial port on the server.
To set up a Direct IP Mode connection:
1.
Connect the Modbus gateway to the network and a Modbus network as described in
previous sections.
2.
Configure the Modbus gateway with the appropriate network settings (using Vlinx
Vlinx Modbus Manager or the web interface).
3.
Configure your software application with the appropriate IP address and port number
to communicate with the Modbus network(s).
