Connectivity Options

Hardy Process Solutions has established itself as an industry leader in the industrial weighing automation world by providing high accuracy and precision measurements. By supporting Industrial Communications Protocols such as EtherNet/IP and PROFINET, Hardy weighing instruments can provide data to other devices on the network.


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.

PROFINET is a standard for industrial networking in automation. It connects devices, systems, and cells, facilitating faster, safer, less costly, and higher quality manufacturing. It easily integrates existing systems and equipment while bringing the richness of Ethernet down to the factory floor.

The ControlNet network is a state-of-the-art control network that 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.

Remote I/O

Under license from the Allen-Bradley, Hardy has developed a Remote I/O Interface for some of its Weight and Rate Controllers. The interface is fast, field proven, requires minimal wiring, and requires no special software drivers.

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

Learn More About Profibus


Ethernet TCP/IP connectivity is available on many Hardy weighing instruments through a standard RJ-45 port. Features such as Embedded Web Server can be accessed via this Ethernet TCP/IP port.

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.

Each weight controller handles analog signals a little differently.

Modbus RTU

Modbus RTU is an open, serial (RS-232 or RS-485) protocol derived from the Controller/Device architecture. It is a widely accepted protocol due to its ease of use and reliability. Modbus RTU is widely used within Industrial Automation Systems (IAS). This wide acceptance is due in large part to MODBUS RTU’s ease of use.
