### 4. Functionality

The W‑M1B107 functions as a remote analog input module that digitizes thermocouple signals and transmits temperature data to a host controller (PLC, PAC, or SCADA system) via RS‑485 using the Modbus/RTU protocol. Each channel operates independently, allowing simultaneous measurement of different thermocouple types. The built‑in cold junction sensor compensates for terminal temperature variations, ensuring accurate readings.

Typical Applications:
- Industrial process temperature monitoring
- Energy management and environmental control
- Building automation and HVAC systems
- Laboratory instrumentation and test benches
- Supervisory control and data acquisition (SCADA)
- Factory automation and production line monitoring
- Power plant and substation temperature sensing

Compatibility:
Fully compatible with standard Modbus/RTU masters, PLCs, DCS, and SCADA software. Works with Advanio’s configuration utility and third‑party Modbus tools.

---

### 6. Installation & Setup

Mounting Options:
- DIN‑Rail 35 mm: Snap the detachable base onto the rail; modules can be docked side‑by‑side using the 14‑pin connector array for power and communication bus continuity.
- Wall Mount: Secure the base with screws using the provided mounting holes.

Grounding:
For aluminum DIN‑rail installations, the rail serves as frame ground. If electrical noise or poor grounding is present, use the provided plastic isolation tab to decouple the module frame from the rail.

Power Wiring:
Connect +VS (10–60 VDC) and GND to the power terminals. Keep cable length short to minimize voltage drop. Only one power source should feed a chain of up to 10 modules (≈ 30 W total).

Communication Wiring:
RS‑485 differential pair (D+, D–) connects in daisy‑chain topology. The first and last nodes should be terminated with 120 Ω resistors. Intermediate modules should not be tapped for signal pickup to avoid reflections.

Address Configuration:
Two rotary switches on the front panel set the Modbus node address (01–247). Power must be cycled after changing the address.

LED Indicators:
- Power LED: Steady ON = power OK; flashes 3× at startup = initialization complete.
- Communication LED: Flashes = active data exchange; steady ON = polling timeout.
- System LED: Flashing = normal operation; steady ON = error or EEPROM fault.

Factory Reset:
Press and hold the INIT push‑button for 3 seconds to restore default settings (address 01, 9600 bps, N‑8‑1).

Software Configuration:
Use Advanio’s PC utility via RS‑485 or converter to set channel types, CJC offsets, and scaling. Configuration parameters are stored in non‑volatile EEPROM.
