Guidance

The high priority external set-point controller does not communicate with the PVED-CL the same way as
other steering devices do. The set-point controller is expected to provide PVED-CL with ISOBUS curvature
commands. This approach needs a special group of messages described in
the state machine shown on the figure Guidance Engage and Disengage State Machine below. Please note
that the state machine is executed only when PVED-CL is in the operational mode, or reduced mode and
the high priority external set-point controller is mapped.
