A Sub-Module is a self-contained unit of logic that performs a specific task. It can be used to:
- Create common, repeatable calculations that can be shared between processes.
- Simplify the appearance of a process in the Logic Editor.
To add a sub-module:
1. Open or create a new user process.
2. In the Logic Editor, right-click and select Sub-Module from the shortcut menu.
The sub-module component is added.
3. Double-click the sub-module component to open it.
When you open a sub-module, the validation toolbar displays a breadcrumb trail with the name of the Sub-Module, and the Back button is activated.
The Logic Editor also changes to display three components that are required by sub-modules:
Flow In: The data flow entry point into this sub-module. This is optional and depends on the external logic. For example, if you want the main process to start at the sub-module, you would attach the Start component to the sub-module's Flow In component.
In: The input value that is to be compared against the Flow In data stream.
Out: The value that the sub-module will output.
4. Add and link components to create the sub-module, as you would do for any other process.
The only requirement is that a sub-module must have inputs and outputs.
You can add further inputs and outputs, and also include other sub-modules, by right-clicking on the background and selecting from the shortcut menu.
In: Add another input value.
Out: Add another output value.
Sub-Module: Create a new sub-module within this sub-module.
Load: Import an existing sub-module (saved as a .sensm file on a computer to which you have access) into this sub-module.
5. Ensure all your In and Out components have a name assigned to them in the Properties panel.
These names will appear as the input and output pins in the sub-module component on the main screen.
6. When you have finished adding and linking components, return to the main process by clicking the Back 
button on the validation toolbar.
7. To save the sub-module component to your computer, click it once to highlight it, and then right-click and select Sub-Module > Save.
You should save the file to a location on your computer, or a computer to which you have network access. The file type must be .sensm.
