ISOBUS: Bringing Greater
Flexibility to Precision Farming

ISOBUS  Class 1 : Implement provides feedback via in-cab display.

 

Example: Track individual bale data from Case IH RB5 series round balers.

ISOBUS Class 2:  Basic controls from tractor or display to the implement.

In this setup, the tractor communicates with the baler through the ISOBUS system. The information from sensors on the baler travels to the monitor in the tractor cab, where the operator can view data such as size, shape, and density of the bales. The operator can adjust settings on the monitor, which sends commands to the baler to make changes in production.

It's a one-way communication or control system where the tractor controls the baler based on the operator's inputs via the monitor.

ISOBUS Class 3 takes the communication and control capabilities a step further. With Class 3, not only does the tractor communicate with the implement, but the implement can also send information back to the tractor. This bidirectional communication allows for more advanced features like implement automation and control over certain tractor functions.

For example, with Case IH large square balers implementing Feedrate Control, the baler can now adjust the tractor's ground speed directly. This level of integration enables more efficient and precise operation, as the implement can respond dynamically to changing conditions in the field.

A modern ISOBUS system consists of tractor, terminal and implement. ISOBUS improves performance through standard functionalities as defined by the AEF.

An ISOBUS functionality is like a separate module on the ISOBUS. One or more functionalities can be bundled together and then interconnect with other products that contain additional functionalities. Only functionalities supported by all components involved are available for a true plug-and-play experience.

Functionality examples include:

• Universal (virtual) Terminal – The capability of operating an implement with any terminal and/or using one terminal for operating different implements
• Auxiliary Control The equipment allows for additional control elements, such as a joystick
• Task Controller – Allows for GPS based control of implements

Equipment requirements — Functionality depends on tractor-implement combination

• Implement and tractor must meet configuration requirements
• Implements must be fitted with ISOBUS electronics and software
• Tractors require specific transmission types, depending on model and desired level of ISOBUS functionality
• Choose the appropriate display for your desired ISOBUS functionality
• Unlock codes — available from the Case IH Partstore — allow ISOBUS Class 3 automation

ISOBUS technology standardizes the user interface across displays — even those from different manufacturers. Each display is consistent in how the operator enters numbers, keys in text, selects from lists and interacts with the system.

This has the added benefit of reducing training. You can train on one piece of equipment and trust  that you will encounter the same interface, whether planting, spraying or harvesting.

The implement loads the graphic user interface, also referred to as virtual implement (VI), into the VT. Once the VI has been loaded into the display, it is saved in the display’s internal memory. When the display detects the same implement again — after shutdown or disconnection, for example — the display automatically loads the VI out of internal memory and displays it.

That means there’s now one place for the user to make settings, get diagnostic information, set controls, etc.

The VT also helps put new technology, components and features into producers’ hands quicker — there’s no need to develop a separate device for each implement.

Consistency, compatibility, standardization. These are among the greatest benefits ISOBUS technology can bring to your farming operation. The powerful AFS Pro 700 display brings together all the controls and data features in a single virtual terminal (VT) display. This display complies with the ISO 11783 specification, allowing it to display data to the user and receive input from the user, regardless of equipment manufacturer.
