Consumer node basis functionality.
It handles:
- up to 4 stages of nodes (TA2/TA3/TA4/TA5)
- power consumption
- node state handling
- registration of passive and active nodes
- Tube connections are on left and right side (from left to right)
- Power connection are on front and back side (front or back)
