3.5 LES431A Modbus Hardened Serial Server Operational Connections
LES431A Modbus Hardened Serial Servers can operate in Direct IP Mode.
Using LES431A Modbus Hardened Serial Servers in Direct IP Mode
A Direct IP connection allows applications using TCP/IP socket programs to communicate with the COM ports on the Modbus
Hardened Serial Server. In this type of application, the Modbus Hardened Serial Server is configured as a TCP server. The socket
program running on the PC establishes a communication connection with the Modbus Hardened Serial Server. 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 Hardened Serial Server to the network and a Modbus network as described in previous sections.
2. Configure the Modbus Hardened Serial Server with the appropriate network settings (using Modbus Hardened Serial Server
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).
