Onewire, Camera device, SPI, I?C, EtherCAT_Master and EK1100
return no host parameters / channels of their own (they're parents/couplers).
Totals: 16 digital inputs (none mapped), 48 digital outputs (41 mapped, 7 free).
Findings worth flagging
Duplicate output mapping (likely a bug)
Application.NVL_Sender.light_livingRoom.l_1 is written by two physical output channels:
| Where | IEC addr |
|---|---|
| K2 ch 10 | %QX1.1 |
| K4 ch 16 | %QX5.7 |
Both physical relays will switch together whenever the variable is written.
One of these should be remapped — usually K4 %QX5.7 would be the one to free up
(based on K4's role as the spillover terminal).

No inputs mapped
K1 (16-channel digital input terminal, %IX0.0..%IX1.7) is wired up at hardware
level but has zero variable mappings. If you have physical switches on K1, the
PLC currently can't see them.
Variable target
All mapped outputs write into Application.NVL_Sender.* — i.e. the global
variable list that is broadcast over UDP to the receiver. This is the "Option C"
relay-feedback pattern referenced in the GVL comment: the program writes the
desired relay state into the NVL_Sender variable, the EtherCAT terminal switches
the actual relay, and the value read back is exactly the value just written.
No outputs are mapped against the application's room/light function block outputs
(fb_room.lights.* / fb_light.light_output). The new fb_room / fb_light
logic is therefore not yet driving the physical relays — that wiring would need
to be done in PLC_PRG (or Lights_new) by assigning each FB output into the
corresponding NVL_Sender.light_*.l_N slot before the IO write phase.
