Ethernet UDP Parameters
Ethernet UDP enables the HI 6600 series instrument to send messages, datagrams, to other hosts on the IP network.
Hardy Port
The Hardy Port provides the service port which is combined with the IP address to provide a unique application socket.
The Hardy Port value can be any 16-bit value between 0 and 65,535.
On the HI 6600 HGM Web page: select the communication menu and the Ethernet TCP/IP submenu, and left click
inside the Hardy Port text field and enter the Hardy Port value.
On the HI 6110 optional display: select the communication menu and use the UP or DOWN button to select the
Ethernet UDP submenu, then select the Hardy Port menu item. The current Hardy Port value will be displayed,
press the ENTER or the RIGHT button if the value needs to be modified.
Modbus TCP
MODBUS is an application layer messaging protocol used to support client / server communications between devices
connected on different types of buses or networks. All the HI 6600 series units have Modbus TCP built-in.There is no
setup in the HI 6600 unit to configure the Modbus TCP.
Refer to the I/O tables in Appendix A for an understanding of the data and format for the Modbus TCP communications.
If you do not have a Modbus PLC available to test the Modbus communications, then you can download the Hardy
Modbus Link test software from the Hardy Web site at http://www.hardysolutions.com. This program can be found
currently on the HI 4050 products page under the Docs & Program.
Modbus TCP Commands and Parameters
The HI 6600 HGM will automatically detect and connect to any available Modbus TCP connection. The system will
show either connected or not connected to display the availability of a Modbus TCP connection.
