Workflow	Data flow
`IsProtocol` flag

Inputs#

Name	Data Type	Description
activate	`Boolean`	Activates the configured action. type
isReady	`Boolean`	The readiness answer to send back. Connect this to the output of your logic. If left unconnected or undefined, `defaultReply` is used instead.

Outputs#

Name	Data Type	Description
success	`Boolean`	`true` value emitted when the action is successfully performed.
error	`Error`	Error emitted if processing fails or a timeout occurs while waiting for a `SendRequest` reply.

Name	Data Type	Default	Description
Default Reply	`Boolean`	`false`	The value to send as the reply if `isReady` is not set when the task activates.

Behavior#

This task sits at the end of the workflow connected to Ready State Requested. When activated, it:

Reads the isReady input value.
Sends that value back as the reply to the pending request.
Cancels the timeout that Ready State Requested started.

If isReady is not set when the task activates, it falls back to the configured defaultReply value of false.

Remarks#

These tasks only make sense when the Automation Scheduled Action is configured to use the DefinedInWorkflow detector. That Detector is for situations where the MES cannot determine readiness from its own data alone, the controller's own workflow logic needs to determine readiness. Ready State Requested and Ready State Reply are the mechanism that the workflow uses. See Detectors for more information on how the DefinedInWorkflow detector works.

To configure this workflow, you must use this task and Ready State Requested, as seen below.

This task uses a context-based data structure called a zone. For more information, see Zones page.
