An Intermediate Signal Catch Event object pauses a Request until that object receives a specific broadcasting Signal designed in Signal Manager from a broadcasting object in any other Request. These paused Requests may be for many different Process models. The object that broadcasts the Signal does not need to be in the same Process model as the Intermediate Signal Catch Event object to receive the broadcast. Pool objects within the same Process model that contain Intermediate Signal Catch Event objects also trigger.
The Intermediate Signal Catch Event object receives any Request data in the broadcasting Signal's payload. Request data in the Signal's payload may be referenced when resuming its Request.
The broadcasting Signal may originate from any of the following:
Intermediate Signal Throw Event object: An Intermediate Signal Throw Event object broadcasts a specified Signal containing none, part, or all of its Request data to all Intermediate Signal Catch Event objects in paused Requests while the Intermediate Signal Catch Event object(s) in those Requests listens for that Signal. In the Signal's payload, the Intermediate Signal Throw Event object may broadcast the entirety of the current Request data to that point in the Request's workflow, the current value of a Request variable, or specific Request data based on an expression. The Intermediate Signal Catch Event object references the Signal's payload when resuming its Request. Use this functionality to resume workflow for potentially multiple paused Requests as soon as the Intermediate Signal Throw Event broadcasts the Signal.
Signal End Event object: A Signal End Event object broadcasts a specified Signal containing none, part, or all of its Request data to all Intermediate Signal Catch Event objects in paused Requests while the Intermediate Signal Catch Event object(s) in those Requests listens for that Signal. In the Signal's payload, the Signal End Event object may broadcast the entirety of the Request data, the current value of a Request variable, or specific Request data based on an expression. The Intermediate Signal Catch Event object references the Signal's payload when resuming its Request. Use this functionality to resume workflow for potentially multiple paused Requests as soon as the Signal End Event object completes its Request.
Each Intermediate Signal Catch Event object functions as follows during its Request:
Workflow in each Request using an Intermediate Signal Catch Event object pauses when it reaches this event. Each Intermediate Signal Catch Event object waits for a specified broadcasting Signal.
The Intermediate Signal Throw Event object or Signal End Event object triggers from a separate Request not necessarily represented in the same Process model as any Intermediate Signal Catch Event object.
That triggering object broadcasts its Signal containing Request data.
Each Intermediate Signal Catch Event object in each paused Request that matches the broadcasting Signal triggers, thereby resuming workflow simultaneously in those Requests. Otherwise, that broadcasting Signal is ignored for those Intermediate Signal Catch Event objects not listening for that Signal and those Requests remain paused.

Select the Signal to Trigger the Object
An Intermediate Signal Catch Event object pauses a Request until that object receives a specific broadcast from a broadcasting object in any other Request in that ProcessMaker Platform instance. The object that broadcasts the Signal does not need to be in the same Process model as the Intermediate Signal Catch Event object that receives the broadcast. Select the Signal that triggers this object.
Follow these steps to select the Signal that triggers the Intermediate Signal Catch Event object:
Select the Intermediate Signal Catch Event object from the Process model in which to select the Signal that triggers it.

Enter the Request Variable to Store the Broadcasting Signal's Payload
When the Intermediate Signal Catch Event object receives a broadcasting Signal for which it is listening, enter the Request variable that stores the Request data in the broadcasting Signal's payload. The Request data within the broadcasting Signal may then be used in the paused Request when the Intermediate Signal Catch Event object resumes that Request.
Follow these steps to enter the Request variable to store the broadcasting Signal's payload:
Select the Intermediate Signal Catch Event object from the Process model in which to enter the Request variable.
