A sub-process can hold a sequence of tasks..

Pulse provides the capability to group tasks into a sub-process. Process variables created in the sub-process level will only belong to that sub-process. Shown below are a split process and a sub-process. Sub-processes can be created and edited in author and orchestrator mode.

To communicate with upper levels, i.e., sub-process input and output ports, one must create process variables on the sub-process level to monitor process output and provide process inputs. In this example, the input process variable will create an input port on the sub-process and the .h3d process variable will create an output port on the sub-process.
