MARS L2 — WET cabinet hardware BOM
WET variant: Industrial PC + Power cabinet with UPS. PLC is line-side;
L2 talks to it over the fieldbus but does not own the PLC cabinet.

Protocols in use (WET)
- L2 ↔ UPS: OWEN IBP120K over RS-232 / USB-CDC (fallback: NUT TCP 3493).
- L2 ↔ PLC (line-side): Modbus TCP / OPC UA / EtherNet/IP depending on
the existing line PLC.
- L2 ↔ scanners: TCP / Serial / USB-HID.
- L2 ↔ printers: TCP / USB / Bluetooth (mobile printers).
Supported device matrix (out of the box)
All drivers below ship in the edge-service package and can be activated
from the L2 Settings UI without a firmware rebuild. Wire-format compliance
is asserted by ProposalDriverComplianceTest (16 tests).

UPS wiring
- Primary: RS-232 DB9 cable from UPS to IPC's COM1 (
/dev/ttyS0).
- Fallback: USB-CDC (IPC enumerates
/dev/ttyACM0 or /dev/ttyUSB0).
- Relay output of UPS → status LED or optional external buzzer.
- Configure in
edge-service.yaml:
ups:
type: OWEN_IBP120K
transport: RS232
devicePath: /dev/ttyS0
baudRate: 9600
pollIntervalMs: 2000
lowBatteryPercent: 40
criticalBatteryPercent: 20
shutdownRelayGpio: gpiochip0:27
Deployment checklist
- Install RED OS / Debian.
- Install the
.rpm / .deb package.
VARIANT=wet SITE=<LUZ|NOV|MIR|RND> sudo -E bash install.sh.- Verify
GET /api/v1/ups/status returns connected=true.
- Simulate a mains cut (physically or
POST /api/v1/ups/simulate) and confirm the journal shows
UPS_ON_BATTERY followed by UPS_RESTORED after power returns.
- Run the HIL matrix from
load-test/HIL_BENCH.md
with the UPS row enabled.
