4.2 Ledningsdiagram
Connect the module according to the following wiring diagram. Ensure correct polarity for the power supply and proper connection for the RS485 communication lines.
Figure 3: Wiring connections for the XY-MD02 module. Connect DC 5-30V to '+' and '-' terminals, and RS485 A+ and B- to their respective terminals.
- DC 5-30V: Connect the positive (+) and negative (-) terminals of your DC power supply.
- RS485 A+: Connect to the A+ line of your RS485 network.
- RS485 B-: Connect to the B- line of your RS485 network.
Caution: Incorrect wiring can damage the module. Always verify connections before applying power.
5. Betjeningsvejledning
5.1 Kommunikationsprotokol
The XY-MD02 module supports the Modbus-RTU protocol. For detailed register addresses and communication commands, refer to the Modbus-RTU protocol documentation specific to this module (typically provided separately or available for download from the manufacturer).
General Modbus-RTU Parameters:
- Baudrate: Typically 9600 bps (configurable).
- Databits: 8.
- Stopbits: 1.
- Paritet: None (configurable).
- Slave adresse: Typically 1 (configurable).
The module will begin transmitting temperature and humidity data over the RS485 bus once powered and correctly configured.
5.2 Dataaflæsning
To read temperature and humidity data, send Modbus-RTU read holding registers (Function Code 0x03) or read input registers (Function Code 0x04) commands to the module's slave address. The specific register addresses for temperature and humidity values will be outlined in the detailed protocol documentation.
Example (conceptual):
- Temperature Register: Address X (e.g., 0x0001)
- Humidity Register: Address Y (e.g., 0x0002)
The returned values will typically be integer representations that need to be scaled (e.g., divided by 10 or 100) to obtain the actual temperature in ℃ and humidity in %RH.
6. Vedligeholdelse
The XY-MD02 module is designed for low maintenance. However, periodic checks can ensure optimal performance:
- Rensning: Keep the sensor area free from dust and debris. Use a soft, dry cloth for cleaning. Do not use abrasive cleaners or solvents.
- Forbindelser: Kontrollér jævnligt ledningsforbindelserne for at sikre, at de er fastgjorte og fri for korrosion.
- Miljø: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent sensor degradation.
Warning: Do not attempt to open the module casing, da det kan ugyldiggøre garantien og udsætte interne komponenter for skade.
7. Fejlfinding
| Problem | Mulig årsag | Løsning |
|---|---|---|
| No power indicator / Module not responding | Forkert strømforsyning voltage or polarity; Loose power connection. | Verify power supply is within DC 5V-30V. Check wiring for correct polarity (+/-). Ensure connections are secure. |
| No data received via RS485 | Incorrect RS485 wiring (A+/B- reversed); Incorrect communication parameters (baud rate, parity, stop bits); Incorrect slave address; RS485 bus termination issues. | Check A+ and B- wiring. Verify communication parameters match the module's settings. Ensure the correct slave address is used. Add or check termination resistors if on a long bus. |
| Unøjagtige aflæsninger | Sensor obstructed or dirty; Module exposed to extreme conditions; Sensor damage. | Clean the sensor area. Relocate the module to a more stable environment. If issues persist, the sensor may be damaged and require replacement. |
