The primary helm gets connected to the Main Helm composite node, which takes precedence over all following nodes, priority from top to bottom goes Main Helm -> 2nd Helm -> 3rd Helm.

This way the highest occupied helm will be the one controlling the connected outputs.

You can add more if needed, just follow the logic structure and copy paste the sections with the composite switchbox and composite read of channel 32 and make sure to hook up the last composite switchbox to the rightmost composite read modules (on/off and numerical).

If you want to add more axes/ or on/off channels simply follow the scheme of the rightmost composite read modules, don't forget to add logical output to the MC as well.

I read the description and it didn't quite make sense. So which helm do I connect to which node?
