Plant HWZ SEQ

The Selmo structure

Selmo describes every machine in a clear, four-level hierarchy:

scssCopyEditPLANT
└── Hardware zones (HWZ)
    └── Sequences (SEQ)
        └── Zones

Level	Function
PLANT	The entire machine, including global safety monitoring and OPC UA
HWZ	Individual controllable unit with its own operating mode logic (Manual/Auto)
SEQ	Logical sequence of a function, e.g. "Clamping", "Checking", "Moving"
Zone	Connection to real hardware: sensor, actuator, pushbutton, mem (internal state)
