===== Discussion =====

An FX Control Command represents an intended operational action directed to an FX logical [[dido:99_annexes:annex-b-terms-and-definitions:f:financial_node|Node]] or FX logical [[dido:99_annexes:annex-b-terms-and-definitions:n:node_role|Node Role]].

The FX Control Command identifies command type, command identifier, target Node or role, issuing Node, requested action, timestamp, authorizing context, expected acknowledgement, and [[dido:99_annexes:annex-b-terms-and-definitions:p:provenance|Provenance]] or [[dido:99_annexes:annex-b-terms-and-definitions:e:evidence|Evidence]] reference.

FX Control Commands participate primarily in the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:c:control_plane|Control Plane]]. They also support the FX Logical [[dido:99_annexes:annex-b-terms-and-definitions:a:audit_and_provenance_plane|Audit and Provenance Plane]] when command issuance and command handling require review or evidence.

===== Note =====

An FX Control Command is not a shell command, orchestration command, [[dido:99_annexes:annex-b-terms-and-definitions:a:api|API]] call, DDS topic sample, [[dido:99_annexes:annex-b-terms-and-definitions:r:rest| REST]] request, [[dido:99_annexes:annex-b-terms-and-definitions:r:rpc]] method invocation, queue message, or deployment instruction.

===== Example =====

An FX Control Command requests that the FX Validation Node report status, retry processing, pause work, resume work, or initiate recovery.
