only.” These signals appear in the crosspoint matrix as logic “sources,” i.e. switches, and
logic “destinations,” i.e. relays or indicators. When a logic source is cross connected to
a logic destination, via the Navigator GUI for instance, then the logic state of the source
will affect the logic state of the destination; the switch will fire the relay. No actual logic
wiring between the switch and the relay is required, it all happens (with sub millisecond
latency, by the way) over the LAN.
A fourth type of logic function in the WheatNet‑IP system is called “action logic.” This
is where you want some kind of system action to be controlled by a logic state. An example
of this might be switches that are programmed to fire a salvo, or make a connection, or
recall a control surface preset. Action logic is easily programmed with the Navigator GUI
and is described in detail along with the other logic types in the GUI section of this manual.
One of the most challenging parts of any logic system is getting it all right, making
sure the senses, polarities, timing, and connections are all correct. In the WheatNet‑IP
system we provide a number of useful tools to help. First of all, logic pin outs, func‑
tions, and polarities can all be changed with a click of a mouse. You can also specify
what you want a logic connection to do when it’s disconnected (go to a specific state
or retain its last setting), and then change your mind about it later. Each logic input or
output is fully independent and not linked into a scheme or template that uses them up
needlessly. The physical logic connections on each BLADE 3 are fully
programmable; they can be all inputs, all outputs, or any combination.
Changing them is simple via the Navigator GUI. The GUI provides
on‑screen indication of logic state changes so you can see that your
buttons are actually triggering the right ports. The BLADE 3s themselves
have a logic test display mode that will show the state changes on every
logic input or output. They also have a front panel LOGIC PORTS
indicators that show status for active logic and direction (in or out)
of the BLADE 3. Best of all, the WheatNet‑IP logic functionality is a
completely integrated part of the WheatNet‑IP system itself and does
not require the Navigator GUI or any other PC to be running to make
it work. The GUI is needed only for programming.
