A plan loses its context
A task can reach a machine without the surrounding assumptions that make it safe, relevant, and understandable for the operator.
ISO 11783 ROLE VIEW / SYSTEM FLOW
One field task.
Many owners.
A field operation is not one continuous protocol story. It is a sequence of handoffs between planning software, machine infrastructure, tractor services, implement functions, the operator, and the record that returns after work.
01 / Orientation
The system only works
at the handoffs.
This view is for people who need an orientation before choosing a role-specific path. It connects the visible stages of a field task without turning the page into a substitute for any individual ISO 11783 publication or product integration plan.
No single team owns the entire flow. Farm software shapes intent; machine services make participation possible; tractor and implement teams deliver physical work; terminal teams help an operator understand it; and records become useful only when their context survives the return journey.
02 / Your critical path
Plan, connect, act,
then learn from the field.
This is a deliberately compact field-task skeleton. Phase 3 will deepen the decisions, forks, and recovery paths; this view stays focused on the main handoffs.
PLAN / P10Farm software frames the taskA field job starts as operational intent that needs context before it can become machine work.JOIN / P05The machine becomes a systemNetwork participation gives the connected tractor, terminal, and implement a shared operating environment.CONTEXT / P09The tractor exposes its sideTractor services provide the machine-side context that an attachment may need during work.WORK / P07The implement delivers the functionThe attachment turns field intent and machine context into its own specialized operation.RECORD / P11Results retain their meaningShared data meaning helps turn observations and outcomes into records that can be interpreted later.RETURN / P10The task returns to managementThe completed operation can be reconciled with the original plan and the decisions made in the field.
03 / What you implement vs consume
The overview connects
what specialists own.
System stageA role team implementsThe stage consumes
PlanFarm context, task intent, review, and record expectationsThe machine's actual configuration and its ability to participate
ConnectPhysical and network participation conditionsA changing set of tractor, terminal, and implement functions
OperateTractor context, implement behavior, and operator interactionA meaningful plan plus safe, current field conditions
RecordObservations, outcomes, and the context needed to interpret themWhat the field operation actually did, including legitimate deviations
ImproveReconciliation, support evidence, and future planning insightClear ownership and trustworthy information from every preceding handoff
04 / Where it breaks
The weak point is often
between two good products.
The machine sees a different system
Attachment changes, startup order, configuration, and product support can change the operating environment before any field function begins.
Responsibility is blurred
A symptom at the operator display may originate in task preparation, tractor services, implement behavior, or the conditions of the field itself.
Work is interrupted mid-story
Pauses, reconnects, changes of operator, and degraded operation test whether each party can explain the current state without guessing.
The result is detached from reality
A returned value is not enough when its field context, operational status, or relationship to the original task has been lost.
05 / Boundaries
This is the map,
not the operating manual.
This is an orientation, not the standard.Use the licensed official ISO 11783 publications for requirements, interfaces, data definitions, version decisions, test criteria, and conformance work.
No protocol material is reproduced.FieldCircuit deliberately omits protected message definitions, identifiers, parameter values, data structures, dictionary entries, tables, figures, and normative procedures.
This does not automate a field task.The flow is a learning skeleton, not a control design, safety case, implementation sequence, or promise that any particular products will interoperate.
Phase 3 adds guided depth.Follow the linked part pages for current detail. The next tutorial phase will expand this overview with decisions and scenarios while keeping the same legal boundary.
