Verify driver map and offset before integration. CH0 starts at protocol address 9; one-based drivers may display 10.
In diagnostic mode the first parameter changes to signal strength. Return to normal mode before using it as process data.
The band and radio operation must match the variant and local installation regulations.
140 × 80 × 40 mm (height × width × depth), excluding antenna, as shown in the WI-MG-STD drawing.
Verify driver map and offset before integration. CH0 starts at protocol address 9; one-based drivers may display 10.
Every WI sensor and module is compatible with WI-MG-STD. Sensor / I/O → wireless link → WI-MG-STD → RS-485 / Modbus RTU → PLC, RTU or cloudLOGGER SCADA. The gateway provides the family Modbus interface.
cloudLOGGER SCADA ↗Industrial instrumentation ↗Modbus RTU is implemented on the gateway serial interface. Radio frequency and operation are verified for the installation country. If MQTT is required, it is provided at the integration layer, not claimed as a native sensor protocol.
Designed to meet Class I, Division 2. This design statement is not third-party certification; hazardous-area selection is verified against unit marking, documentation and installation conditions.
