5. Setup
5.1 Panel Mounting
- Cut an opening in the control panel according to the dimensions provided in the installation guide (refer to the separate installation template for precise measurements).
- Insert the MT8100iE HMI into the cutout from the front.
- From the rear of the panel, insert the four mounting brackets into the slots on the HMI unit.
- Tighten the screws on the mounting brackets evenly until the HMI is securely fastened to the panel. Do not overtighten.
5.2 Power Connection
- Connect a 24V DC power supply to the power input terminal block on the rear of the HMI.
- Ensure correct polarity (+ and -).
- Secure the connection firmly.
5.3 Communication Connections
- Serial Ports: Use the COM1 (RS-232) and COM2 (RS-485 2W/4W) ports to connect to PLCs or other serial devices. Refer to your PLC's documentation for specific wiring diagrams.
- Ethernet Port: Connect an Ethernet cable to the RJ45 port for network communication with PLCs or for remote access.
- USB Ports: Use the USB host ports for connecting USB flash drives for project transfers or other peripherals.
6. Operating Instructions
6.1 Powering On
Once all connections are secure, apply power to the HMI. The power indicator LED will illuminate, and the HMI will boot up, displaying the configured project.
6.2 Project Download
To load a new project or update an existing one:
- Create or modify your HMI project using the EasyBuilder Pro software on a PC.
- Connect the PC to the HMI via Ethernet or USB.
- In EasyBuilder Pro, use the 'Download' function to transfer the project to the HMI.
- The HMI will restart with the new project loaded.
6.3 Touchscreen Operation
The MT8100iE features a resistive touchscreen. Use your finger or a non-sharp stylus to interact with the on-screen elements such as buttons, input fields, and displays.
6.4 PLC Communication
The HMI is designed to communicate with various PLCs. Ensure the communication settings (protocol, baud rate, station ID, etc.) configured in your EasyBuilder Pro project match those of your connected PLC.
7. Maintenance
Regular maintenance ensures optimal performance and longevity of your HMI.
- Cleaning: Use a soft, damp cloth to clean the screen and casing. Do not use abrasive cleaners or solvents. Ensure no liquid enters the device.
- Firmware Updates: Periodically check the Weintek website for firmware updates to ensure your HMI has the latest features and bug fixes.
- Fuse Replacement: If the HMI does not power on, check the fuse located on the rear panel. Replace it with a fuse of the same type and rating if necessary. Always disconnect power before replacing the fuse.
- Environmental Conditions: Ensure the operating environment remains within the specified temperature and humidity ranges to prevent damage.
8. Troubleshooting
This section provides solutions to common issues you might encounter.
| Problem | Possible Cause | Solution |
|---|---|---|
| HMI does not power on. | No power supply, incorrect wiring, blown fuse. | Check power connection, verify wiring polarity, replace fuse if blown. |
| Touchscreen is unresponsive. | Screen calibration issue, hardware fault. | Perform screen calibration (refer to EasyBuilder Pro documentation), contact support if issue persists. |
| Cannot communicate with PLC. | Incorrect communication settings, wrong cable, PLC offline. | Verify communication protocol, baud rate, and station ID in EasyBuilder Pro. Check cable connections. Ensure PLC is powered on and running. |
| Project download fails. | Network issue, incorrect IP address, firewall blocking. | Check network cable, verify HMI and PC IP addresses are in the same subnet. Temporarily disable firewalls for testing. |
