The ReleaseProductionOrder Method is used to make a production order available to a machine module for orchestrated execution in a production line (Process Cell according to ANSI/ISA-88.00.01-2010 Physical Model).

When the method is executed successfully, a new ProductionOrderExecutionStateMachine is instantiated for the released production order when not already existing.

When the ProductionOrderExecutionStateMachine is in state Unreleased, the successful execution of the method causes the state transition to Releasing.

The signature of this Method is specified below.
