Permanent connections are used for part 1 controllers that still need to send data regardless if its a master or slave unit. This can be used for things like guard buzzers, lighting, emergency stop buttons, etc

There is already a example set up inside the Part 1 controller with a permanent on/off input on channel one. You can stack these permanent connections on top of each other, the end result should be the 'Part 4 Feed Stack' and 'Coupler Forward/Aft Composite Input' will eventually feed into the channel 32 composite write and second signal on the composite switchboxes respectively. It is important you first familiarise yourself with the connection train on the given example and the standard Part 1 controller. All of these components can be found in the top right of the controller.

One thing to point out is the 'Coupler Forward Composite Input' should eventually feed into the 'Coupler Aft Composite Output' and vice versa with the aft controller feeding into the forward input.
