7... HYPERNET™ ICON BASED PROGRAMMING

USING THE OMP-MODL7-12

UPDATE (BLUE)

Update commands are a special type of signal that is generated

ONLY by Sample Rate Clock icons. This signal is connected to

the Update input on icons and commands them to update their

outputs. As with the other signal types, HyperNet only allows

Update signals to be connected to Update type terminals on

icons.

Adding Signal Connections Between Icons

Connections between two icons are drawn by locating the mouse

cursor over the first icon’s terminal (note how the cursor changes

when properly located over a terminal), clicking and holding the

button down, then dragging a connection line to the second icon’s

terminal and releasing the button.

The direction that signal connections can be dragged on the

workspace is limited to minimize potential problems with feedback

and/or race conditions. Connections can only be drawn from the left

to the right on the workspace.

During the connection process, HyperNet checks and disallows

recognized illegal connections such as:

♦ Differing terminal types cannot be interconnected. For

example, a Data terminal cannot be connected to a

Logic terminal.

♦ Output terminals can only connect to Input or Enable

terminals.

♦ Connections cannot be made between terminals on the

same icon
