سلسلة HMI B TPC7031Bin

The B-Series IoT Screens establish network connectivity through dual-channel support for both 4G cellular and WiFi wireless communication, thereby facilitating comprehensive remote Operation and Maintenance (O&M) capabilities not only for the screens themselves but also for the various peripheral devices that are interconnected with them. This integrated connectivity solution ensures seamless monitoring, management, and control from a centralized remote location, enhancing overall system reliability and operational efficiency.

*Note: Wireless Expansion only supports either Wi-Fi or 4G (two options for one).

1.5  Product Maintenance

1.5.1  Replacement battery

Battery Location: On the circuit board inside the TPC product.

Battery Specifications: CR1220 3V Lithium Battery (model and voltage retained as standard identifiers).

Battery Removal: Remove the fixing glue above the battery, gently pull the positive terminal clip, and the battery will pop out automatically.

Battery Installation: First place the battery into the positive terminal clip, then press the other end gently under the plastic clips. Verify that both plastic clips and the metal positive terminal clip are properly engaged.

Installation Notes:

1.Avoid short-circuiting the positive and negative terminals of the battery during installation.

2.For 4G IoT screens, remove the expansion board first and ensure the pinholes of the expansion board are aligned when reinstalling.

1.5.2  Touch calibration

Access the TPC system settings interface, press and hold a blank area for 3 seconds to launch the touch calibration program.

TPC Calibration Process:Use a stylus or finger to tap and hold the center point of the crosshair cursor. Release only when the cursor moves to the next point.

Repeat this action until prompted with "New calibration settings have been determined".

Tap the "Confirm Calibration" button to save the settings and exit the calibration program.

Place your finger lightly and accurately on the center of the crosshair cursor and hold it for at least one second as the target moves across the screen. Repeat this action.

1.5.3  Triple Protection Film Application

Applying a triple protection film to the TPC can effectively prevent contamination and corrosion caused by dust, oil stains, and other substances generated during production. Therefore, if necessary, the TPC can be protected with a triple protection film. This section takes the 1271Gn model as an example; the film application steps for other TPC models are similar.

l Preparation Tools: Matched triple protection film for TPC (available through the TPC's purchase channel), dust-free cloth, anti-static environmentally friendly cleaner, and roller.

l Operation Steps：

1) Clean the screen. Use a dust cloth to wipe away dirt from the front panel to prevent bubbles when applying the screen protector. If the TPC surface is heavily contaminated, use a cleaning agent to help clean contaminants in the crevices around the edges.

2) Remove the factory-installed PET protective film and clean any residue to prevent bubbles from forming during application.

3) Peel off a corner of the backing film on the right side. Align the right side of the film with the right side of the TPC. With your left hand, slowly peel off the backing film, and with your right hand, apply even pressure to gently push the film onto the screen from right to left

4) After applying the film, use a roller to press the adhesive backing firmly to prevent air bubbles.

l Precautions:

1）Before applying the Triple Protection Film, the factory-installed PET protective film must be peeled off.

2）The Triple Protection Film is a consumable. If edge lifting or bubbling is detected, it should be replaced with a new one.

3）When replacing the Triple Protection Film, peel it up from the bottom right corner of the front panel. Be

careful not to scratch the sealed film.

2 Project Download

Step 1:Power the TPC with a 24V DC power supply. After startup, a "Starting Up" progress bar will appear on the screen. At this point, tap the TPC screen ① to enter the Startup Configuration Interface; if no operation is performed, it will automatically enter the Project Runtime Interface.

Step 2: Click the System Parameter Settings button ②. Enter TPC System settings interface.

Step 3: Select the Network Settings tab ③, and configure... TPC IP Address 4, TPC default I P Address is 200.200.200.190 .

Step 4:Connect the computer to the TPC using a network cable, and set the computer's IP address to the same subnet as the TPC's LAN port IP.

Step 5: Use MCGS Pro Open TPC Project, click to download project ⑤, Open the download configuration properties page and select "Online" as the run mode . Select the connection method "TCP/IP" "Network"⑦ Enter the target machine name TPC of IP Address ⑧ , Click "Download Project" (⑨). After the download is successful, click "Start & Run" (⑩) or... TPC The "Enter Runtime Environment" button on the interface runs the screen-side project.
