What we have designed is a flow where if you hold GPI buttons 1 and 2 down, PC4 source will be routed to PC4
destination. And if PC 4 source is routed to PC4 destination then LCD button 1’s indicator will be turned on. If
anything else is routed to that destination then the Indicator will be off.
The system is intelligent enough to recognize when flows should be joined into a single logical entity.
Cut, Copy, and Paste
Cut, copy, and paste are standard tools, and require little explanation. You can select a flow by clicking in the
area surrounding a flow. At that point the cut and copy icons will be available. Cut will remove the flow from the
view and place it on the clipboard and copy will just make a copy of it on the clipboard. Once a flow exists on the
clipboard it can be pasted back into the view or into any other view.
The system does make some assumptions regarding pasting. If you copy a flow and paste it back into the same view,
the system assumes you are trying to duplicate the functionality with a new set of endpoints. So it will actually clear
the outer start and endpoints of the pasted flow so you can select new ones.
It is important to reiterate that none of the changes involved in a cut/copy/paste operation ever become a reality on
the system until you click the Apply button and that clicking the cancel button will return to the last known applied
state.
Flow Titling
Each flow can be assigned a title. If you double click in the whitespace surrounding a flow, the system will ask
you for a title for the flow. Then click apply to apply the title. Flows that have titles will display the titling text
underneath the flow.
Titling is a very important habit to form as it makes it much easier to glance at a Logic Flow view and understand
the states of the flows and which flows are performing which functions. Additionally, it is useful as an
organizational tool as flows with titles will be displayed alphabetically within the view. Otherwise the flow order
within the view is somewhat arbitrary.
