4.2 | Understanding COMMAND Status

The COMMAND Status area is shown at the bottom-right of the Apply View and provides a quick indication of the current operating state of the COMMAND ECU.

Operators should check COMMAND Status before attempting to engage Automatic Control. The status message indicates whether the system is ready to engage, currently engaged, waiting for an operator action, or unable to operate due to a warning, fault or incomplete setup condition.

Status Colours

The coloured frame around the COMMAND Status area provides a quick visual indication of the current system state:

• Green indicates that Automatic Control is currently engaged.
• Yellow indicates that all requirements have been satisfied and the system is ready for Automatic Control engagement.
• Red indicates that operator action, further setup or fault correction is required before Automatic Control can operate normally.

Typical Workflow

Before engaging Automatic Control:

1. Confirm GNSS has achieved RTK fix.
2. Confirm the correct project or design surface is loaded.
3. Check COMMAND Status.
4. Resolve any warnings or required actions.
5. Engage Automatic Control only when COMMAND Status shows Ready to Engage.

Ready to Continue

Once COMMAND Status shows Ready to Engage, the system is ready for Automatic Control engagement.
