A standard Output Pulse, to move onto the next Node along the Logic Branch, once this Node has finished its execution.

Example

To visualize how the Node works a bit better, refer to the images below. The first is an example DBC file, which would have been added in the CAN Project Settings. There are two Messages and two Signals, each of which correspond to one of the Messages.

When the connection has been added in Project Settings and those changes are saved, the user can select the desired Message Name -- here Message1 -- which will make an output appear called Signal1. If a Message has multiple Signals -- for example if Message1 had two Signals called Signal1a and Signal1b -- all appear as outputs of the Node.
