If CommandMask ReassignControlCmd is set, the EstablishConnections implementation shall call the ReassignControl Method on each element in ControlGroups for each element in ConnectionEndpointConfigurations. If ControlGroups is null or empty, ReassignControlResult shall be set to null or empty (see 10.15).

This command shall pass the string representation of the NodeId of the ConnectionEndpoint as LockContext Argument to ReassignControl.

The EstablishConnections implementation shall stop processing this command on the first error and shall abort processing as described in 6.2.4.3.11.

The possible StatusCodes for the ReassignControlResult are formally defined in Table 15. The possible StatusCodes for the FunctionalEntityNodeResult are formally defined in Table 11. The possible StatusCodes for the ConnectionEndpointResult are formally defined in Table 12.
