Behavior#
When activated, this task sends the recipe list back to the request that the Recipe List Request task is waiting on, which unblocks the MES. The recipeList input is expected to carry an array with the names of the recipes available at the equipment.
This task must run in the same workflow branch (zone) as the request it answers. If there is no pending request to answer, the task emits Error instead.
Inputs#
| Name | Data Type | Description |

Remarks#
This task pairs with the Recipe List Request task, which listens for the request that this task replies to. It must be executed within the zone created by that task.
MES reads each item of the list as a recipe name, or as an object with a non-empty Name, and fails the request for an item without a name. Link an array: a text is sent as one item without a name. See Connect IoT - MES Interoperability Scenarios Tutorial.
This task uses a specific structure of context-based data called zone. More information on this topic can be read in the Zones page.
