MESR321 Operational Connections
Using MESR321s 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
or the web interface).
3. Configure your software application with the appropriate IP address and port
number to communicate with the Modbus network(s).
