EtherNet/IP is an industrial networking standard that takes advantage of commercial off-the-shelf Ethernet communication chips and physical media. IP is short for 'Industrial Protocol'. Unlike the many options available in the NEW industrial Ethernets, EtherNet/IP uses an open protocol at the application layer.

The ControlNet network meets the demands of real-time, high- throughput applications, such as high-speed plant network communications. The ControlNet network combines the functionality of an I/O network and a peer-to-peer network while providing high-speed performance for both functions.

The DeviceNet Network is an open, global industry-standard communication network.

Allen-Bradley Remote I/O (RIO) interface is available for some of Hardy's weight controllers.

Modbus TCP/IP is a serial communications protocol published by Schneider Electric for use with its programmable logic controllers (PLCs).

The PROFIBUS Interface Option is available on several Hardy weighing instruments.

Hardy's Analog output option provides both 0-20mA to 4-20mA and 0-5V to 0-10V simultaneously with 16,000 counts of resolution.

A Serial interface comes standard on most of Hardy's weight controllers.  Hardy provides various versions of standard serial communications based on the product model purchased.
