UniOP ETT-VGA-0045 10.4-Inch VGA HMI Touch Panel

Description

Key Technical Specifications

The Exor technical note identifies ETT-VGA-0045 specifically as a 10.4-inch TFT color graphic unit with 640 × 480 resolution, touchscreen, 11-key keypad, PLC/PC-Printer/Aux ports, and a 32 MB user-memory configuration in its ordering information. The same document’s general technical table lists 8 MB SSFDC user memory, so the memory specification should be checked against the actual hardware revision before procurement or replacement.

The same documentation specifies 18–30 V DC input, approximately 700 mA maximum consumption at 24 V DC, 0–50 °C operating temperature, IP65 front protection, 311 × 220 mm front dimensions, and a 292 × 202 mm panel cutout.

Product Introduction

The UniOP ETT-VGA-0045 is a legacy 10.4-inch industrial HMI designed for operator visualization and control of PLC-based automation equipment. It provides a 640 × 480 VGA TFT display, resistive touchscreen, 11 physical keys, RS-232/RS-422/RS-485 serial communication, and optional fieldbus connectivity.

Its panel-mounted construction uses an IP65-rated front face and supports 18–30 V DC operation. The combination of serial PLC interfaces, recipe and alarm functions, hardware RTC, and UniNET support makes it suitable as a replacement interface for legacy machine-control installations where the existing project and communications configuration must be retained.

Installation & Configuration Guide

Stage 1 — Pre-Installation | ~5 minutes

1. Disconnect the 18–30 V DC supply before removing the existing HMI.
2. Record the existing serial wiring, communication parameters, connector orientation, and any external fieldbus module.
3. Photograph the old unit before disassembly. This is particularly important for RS-232/422/485 wiring because connector pin assignments and communication mode must match the PLC configuration.
4. Back up the existing HMI project before changing hardware.
5. Confirm the cabinet cutout is 292 × 202 mm and that the panel thickness does not exceed 5 mm.

⚠️ Do not assume another UniOP ETT or ECT model is a direct replacement solely because the display size or VGA designation is similar. Verify the communication ports, project compatibility, mounting dimensions, and hardware revision.

Stage 2 — Remove the Existing Panel | ~5 minutes

1. Isolate the DC supply and verify that the HMI is de-energized.
2. Label each communication and power cable.
3. Disconnect the PLC communication cable, auxiliary connections, and power wiring.
4. Release the rear mounting hardware.
5. Remove the old HMI carefully without damaging the cabinet gasket or cutout.

Stage 3 — Install ETT-VGA-0045 | ~10 minutes

1. Inspect the replacement unit for damaged connectors, touchscreen damage, loose hardware, or evidence of storage damage.
2. Verify that the front dimensions and cabinet opening correspond to 311 × 220 mm front size / 292 × 202 mm cutout.
3. Reconnect the power and communication wiring exactly according to the original installation documentation.
4. Verify the PLC interface type: RS-232, RS-422, RS-485, or CL 20 mA.
5. Reinstall any optional auxiliary/fieldbus module required by the original configuration.
6. Secure the mounting hardware evenly so the front gasket seats correctly.
7. Check that no conductive debris or loose wiring is present behind the panel.

Stage 4 — Power-On & Commissioning | ~10 minutes

1. Apply the specified 24 V DC nominal supply within the 18–30 V DC operating range.
2. Confirm that the display and backlight initialize correctly.
3. Check touchscreen response across the complete active area.
4. Verify all 11 keys.
5. Confirm PLC communication using the original baud rate, protocol, station/node settings, and serial interface.
6. Load or restore the correct UniOP project if the replacement unit does not retain the required application.
7. Test representative HMI functions: status display, command inputs, alarms, recipes, and communications.
8. Confirm the machine remains in a safe operating state before returning it to production.

⚠️ If the display powers up but the PLC does not communicate, check the physical interface first. RS-232, RS-422, and RS-485 are electrically different interfaces; changing the communication cable without verifying the interface type can create a nonfunctional installation.

FAQ

1. What is the UniOP ETT-VGA-0045?

It is a 10.4-inch UniOP industrial HMI/operator panel with a 640 × 480 TFT display, resistive touchscreen, 11 keys, serial PLC interfaces, and optional fieldbus connectivity.

2. What power supply does the ETT-VGA-0045 require?

The documented supply range is 18–30 V DC, with maximum consumption of approximately 700 mA at 24 V DC. Confirm the cabinet power supply and wiring before installation.

3. Is obsolete?

It should be treated as a legacy UniOP/Exor HMI. The available Exor technical documentation is dated 2012, while current aftermarket listings continue to identify the exact part number. Availability therefore depends on remaining new-old-stock, used, or refurbished inventory.

4. Does use a touchscreen?

Yes. The technical documentation specifies a resistive touchscreen in addition to the 11-key keypad.

5. What is the panel cutout size?

The required cabinet cutout is 292 × 202 mm, with a front dimension of 311 × 220 mm. Maximum documented panel thickness is 5 mm.

6. Can another UniOP HMI replace directly?

Do not assume direct interchangeability. A replacement must be checked for mechanical dimensions, communication interfaces, electrical requirements, project/software compatibility, keypad arrangement, and optional fieldbus hardware. Similar-looking UniOP models can have different hardware configurations.

7. Why do different sources show different memory capacities?

The original Exor technical note itself contains two different memory references: its technical-data section lists 8 MB SSFDC user memory, while the ordering description specifies 32 MB user memory. This should be treated as a hardware/documentation revision issue rather than silently choosing one value. Verify the memory marking or exact revision on the unit being purchased.
