Recorded workflow
An operator-triggered pattern can be captured as a coordinated sequence of supported machine actions.
ISO 11783 MACHINE SERVICES / PART 14
Sequence
control
Part 14 defines a sequence-control system that can record and replay coordinated operator-triggered tractor and implement functions, such as work patterns used repeatedly in field operations.
01 / Identity & role
Repeat coordinated work
with deliberate control.
ISO 11783-14:2013 is titled Sequence control. The referenced publication is the first edition, issued in 2013.
Its role is to define a system that records multiple sequences of operator-activated tractor or other connected control-function actions and replays them when the operator commands it.
02 / The problem it solves
Repeated field patterns
span more than one machine function.
Field operations often involve recurring transitions where tractor and implement actions must happen in an understood order. Repeating them manually increases workload and can make outcomes inconsistent when conditions allow the same pattern to be used again.
Part 14 provides a common conceptual framework for recording and replaying coordinated sequences across connected functions. It addresses repeatable operator workflow, not unrestricted machine autonomy.
03 / Position in the stack
Part 14 coordinates actions
at the operator-workflow layer.
It is an application-level coordination service. It depends on reachable tractor and implement functions and requires product-specific safety and operating constraints around every action it may involve.

04 / Key concepts
Record, replay, supervise,
and respect operating context.
Commanded replay
The operator initiates replay; the system is not a substitute for continuous supervision or field judgement.
Cross-function coordination
The value comes from linking supported tractor and implement functions into one repeatable workflow.
Operating context
A sequence appropriate in one location, crop stage, implement setup, speed, or terrain condition can be inappropriate in another.
Safety boundary
Sequence control must coexist with product safety concepts, interlocks, operator authority, and machine-specific limits.
05 / Who implements it
Coordinated replay requires
shared responsibility across products.
RoleDirect responsibilitySafety and usability question
Tractor OEMExpose supported tractor functions within the product safety conceptWhich actions can participate, and under what machine conditions must they be refused or interrupted?
Implement makerExpose only supported implement behaviorHow does the implement communicate readiness, refusal, state change, and fault conditions?
Terminal developerMake recording, selection, confirmation, state, and interruption clear to the operatorCan the operator understand what will happen, what is happening, and how to stop it?
FMIS developerUsually does not execute in-cab sequencesWhich operational records or setup context may be relevant without assuming the sequence is an agronomic recommendation?
06 / Interactions
Part 14 joins repeated field
work into one supervised sequence.
This is an original teaching flow; it contains no sequence definitions, action lists, state diagrams, or product control procedures.

07 / Boundaries
Sequence control is not
unattended autonomy.
This page is not ISO 11783-14.Use the licensed official publication for sequence definitions, function behavior, eligibility, state handling, safety requirements, and conformance work.
No sequence content is reproduced.FieldCircuit omits action definitions, states, triggers, timing, data fields, commands, tables, examples, figures, and normative procedures.
Replay is context-dependent.A stored pattern must not be assumed safe or appropriate after changes to machine configuration, implement, field conditions, crop, terrain, speed, or operator intent.
The operator remains responsible.Follow product manuals, safety procedures, local rules, and active supervision; stop or avoid a sequence whenever the operating context is not suitable.
