Setup
- Power Supply: Connect the HMI to a stable DC power source. Ensure the voltage matches the device's requirements.
- Software Installation: The necessary software for the HMI is provided free of charge. If you cannot download it, please contact support to receive it via email. Install the software on your computer.
- Communication Cable: To establish communication between the HMI and your PLC, a specific cable is required. Please specify the brand and model of your PLC when requesting the appropriate communication cable.
- Initial Connection: Connect the HMI to your computer using the appropriate USB port (USB-B for most models). Use the provided software to configure the HMI settings and upload your project.
Operating Instructions
Once the HMI is powered on and configured, it operates as an interface for your industrial control system. The touch screen allows for intuitive interaction with your programmed applications.
- Touch Interface: Navigate through screens and interact with controls by touching the display.
- Data Transfer: Utilize the USB-A ports (if available on your model) for quick data transfer and backup of project files or logs.
- Communication: The COM ports facilitate communication with PLCs and other serial devices. Ensure correct protocol settings (232, 485, 422) are configured in the HMI software.
- Ethernet Communication: For models with an Ethernet port (e.g., TG765-ET), connect to a network to communicate with MODBUS TCP devices or S7-1200 PLCs.
Maintenance
Regular maintenance ensures the longevity and optimal performance of your HMI unit.
- Cleaning: Gently wipe the touch screen with a soft, lint-free cloth. For stubborn marks, use a screen cleaner specifically designed for electronic displays. Avoid abrasive materials or harsh chemicals.
- Environmental Conditions: Ensure the HMI operates within its specified temperature and humidity ranges to prevent damage.
- Firmware Updates: Periodically check for firmware updates from the manufacturer to improve performance and add new features.
- Data Backup: Regularly back up your HMI project files and critical data to an external storage device using the USB-A port or network connection.
Troubleshooting
This section addresses common issues you might encounter with your HMI.
| Problem | Possible Cause | Solution |
|---|---|---|
| HMI does not power on. | No power supply or incorrect voltage. | Verify power cable connection and ensure the DC power supply meets the HMI's voltage requirements. |
| Display is blank or distorted. | Loose display cable, software issue, or backlight failure. | Restart the HMI. If the problem persists, check internal connections (if accessible) or contact technical support. |
| Communication with PLC fails. | Incorrect cable, wrong communication settings, or PLC not responding. | Ensure the correct communication cable is used. Verify COM port settings (baud rate, data bits, parity, stop bits) in both HMI and PLC. Check PLC status. |
| Touch screen is unresponsive. | Software freeze or physical damage. | Perform a soft reset of the HMI. If unresponsive, power cycle the device. If physical damage is suspected, contact support. |
