Delta TP02G-AS1

The Delta TP02G-AS1 is a compact, entry-level Text Panel HMI designed for basic industrial control applications.¹ It is the smaller sibling of the TP04G, offering a 2-line display. This unit is a “workhorse” for simple machines where cost and physical durability are more important than high-resolution graphics.

Unlike touchscreens, this unit relies entirely on a membrane keypad, making it ideal for environments where operators wear heavy gloves or where screens are prone to getting dirty.²

1. Display and Interface

The “02” in the model name signifies that the screen is designed to display 2 lines of text comfortably.

• Display Type: STN LCD (Monochrome).

• Resolution: ³$160 \times 32$ pixels.⁴

   

• Backlight: Yellow-green LED.

• Keypad: Features 12 user-defined function keys (F1–F12) that can be programmed to trigger specific PLC bits, along with numeric and directional keys for parameter adjustment.

2. Connectivity and Communication

The TP02G-AS1 is versatile in how it talks to other industrial hardware:

• COM 1 (RS-232):⁵ A 9-pin D-sub port used for downloading programs from a PC or for point-to-point communication with a controller.⁶

• COM 2 (RS-485):⁷ A 2-pin/3-pin terminal interface. This is the most common port for industrial networking, allowing the HMI to control multiple VFDs (Variable Frequency Drives) or PLCs via Modbus RTU/ASCII.

   

• Protocol Support: Native drivers for Delta DVP series PLCs, but it also supports Mitsubishi FX, Omron C-series, and Siemens S7-200.

4. Key Advantages

• Extreme Durability: Physical buttons don’t suffer from the “ghost touches” or calibration drift that can affect cheap touchscreens in high-vibration environments.

• Password Security: You can set up multi-level passwords to ensure only authorized personnel can change sensitive machine timers or setpoints.

• Macro Support: Allows for simple internal logic calculations (like scaling a raw sensor value to a readable temperature) without using the PLC’s processing power.

5. Mounting & Dimensions

• Panel Cutout: 137 mm (W) x 68 mm (H).

• External Dimensions: 147 mm (W) x 78 mm (H) x 35 mm (D).

Maintenance Tip:

If the text becomes hard to read over time, it is usually a contrast issue rather than a failing screen. To fix this, enter the System Menu (usually by holding the “Esc” key during power-up or for 5 seconds) and navigate to the LCD Contrast setting to brighten the text.
