The Weintek M02 is a modular Wi-Fi Expansion Module designed to add wireless connectivity to Human Machine Interfaces (HMIs). It supports IEEE 802.11b/g/n Wi-Fi standards, providing flexible and robust wireless communication for industrial applications.
Function Description:
The primary function of the M02 module is to enable Wi-Fi connectivity for compatible HMIs. This allows the HMI to connect to wireless networks, facilitating data exchange, remote monitoring, and control without the need for physical Ethernet cables. The modular design ensures easy integration with existing HMI systems. The module can also transform the HMI into a wireless hotspot, enabling other Wi-Fi devices to connect to the HMI and share its internet connection, which can be particularly useful in environments where direct internet access for multiple devices is limited.
Important Technical Specifications:
- Network Standards: Supports IEEE 802.11b, IEEE 802.11g, and IEEE 802.11n, ensuring compatibility with a wide range of Wi-Fi networks.
- I/O Port: Features an SMA Female Connector for the antenna and a Male Connector to HMI for power and data.
- Input Power: Operates on 5VDC, supplied by the HMI.
- Power Consumption: Draws 900mA at 5VDC, indicating efficient power usage.
- Voltage Resistance: Can withstand 500VAC for 1 minute.
- Isolation Resistance: Exceeds 50MΩ at 500VDC, providing good electrical isolation.
- Enclosure: Made of plastic, offering a lightweight and durable housing.
- Dimensions: Compact size of 54.5 x 80 x 24.1 mm, designed for minimal protrusion when installed on an HMI, saving space in control cabinets.
- Weight: Approximately 80g, adding negligible weight to the HMI.
- Mounting: Connects via HMI connector and diagonal screw fastening, ensuring a secure attachment.
- Protection Structure: The M02 module is IP20 Compliant, while the included antenna is IP66 Compliant, offering protection against dust and water ingress for the antenna.
- Operating Temperature: Functions reliably in a wide temperature range from 0°C to 50°C (32°F to 122°F).
- Storage Temperature: Can be stored in temperatures ranging from -20°C to 60°C (-4°F to 140°F).
- Relative Humidity: Operates in 10% to 90% relative humidity (non-condensing).
- Vibration Endurance: Withstands vibrations from 10 to 25Hz (X, Y, Z direction, 2G for 30 minutes), making it suitable for industrial environments.
- Certifications: CE marked, indicating compliance with European safety, health, and environmental protection standards.
- Software Compatibility: Configurable using EasyBuilder Pro software.
Usage Features:
- Easy Integration: The modular design allows for straightforward attachment to compatible HMIs.
- Optimal Signal Strength: Includes a magnetic mount antenna that can be positioned optimally to maximize signal strength, overcoming potential signal obstructions within control cabinets. The antenna cable is 2000mm long, providing flexibility in placement.
- User-Friendly Configuration: Wi-Fi settings can be configured through two main methods:
- Internet Browser: By connecting the HMI to a PC via an Ethernet cable and accessing the HMI's IP address in a web browser (IE, Chrome, or Firefox), users can log in to the system settings and configure Wi-Fi parameters, including selecting an access point (AP) and defining encryption types.
- HMI Touchscreen: Users can access the HMI's system settings directly via the touchscreen interface. After tapping the start button and entering the password, the Wi-Fi tab allows for configuration of Wi-Fi Connection and Wi-Fi Hotspot settings.
- Hotspot Functionality: The HMI can be configured to act as a wireless hotspot, sharing its internet connection with other Wi-Fi devices. This feature is particularly useful for connecting other devices like smartphones or tablets for monitoring or data access, especially in areas with limited network infrastructure.
- Compact Design: Its small footprint and minimal protrusion when installed help avoid space issues in crowded control cabinets.
Maintenance Features:
- Non-Hot Swappable: It is crucial to note that the M02 module does not support hot-swapping. It must be connected to the HMI before powering up the HMI to prevent potential damage or malfunction.
- Durable Construction: The plastic enclosure and IP20 compliance (for the module) contribute to its durability in industrial settings. The IP66 compliant antenna further enhances its robustness against environmental factors.
- Software-Based Configuration: Configuration through EasyBuilder Pro and web browser interfaces simplifies management and troubleshooting of Wi-Fi settings.
- Clear Status Indicators: The configuration interfaces provide clear status information (e.g., "Connected" to a specific AP) to help users monitor the Wi-Fi connection.
