Is there Ethernet IP interface sample code for my HI 3000 or 4000 series units?

We do not have any sample code as there really is no code necessary. The HI 3000 units, which include the HI 3030, HI 3010, and the HI 4000 units, which include the HI 4050, and HI 4060, when set up in the PLC configuration will have input and output data locations for it. This will be basically discrete data. This will be where the input and output data for the unit is written/read.

The unit itself would be set up in its "Mapping" to designate what data will be sent out and what it will do with any data received through this table. The user needs to go online with the unit over the TCP/IP Ethernet connection (not the Ethernet I/P) to set up the mapping. This is explained in the manual, which can be downloaded from the Hardy Process solutions Online Support webpage.
