UniOP CP02 series high-end compact HMI

UniOP CP02 series high-end compact HMI

In industrial automation and control systems, the human-machine interface serves as an interactive bridge between operators and underlying control devices, and its performance, reliability, and ease of use directly affect production efficiency and operational experience. The UniOP CP02 series compact HMI devices, as entry-level products in the UniOP family, are widely used in various fields such as mechanical equipment control, process automation, building automation, etc. due to their small size, rich functions, and high cost-effectiveness. This series includes two models, CP02F-02 and CP02R-04, which use vacuum fluorescent display screens and monochrome LCD display screens respectively, providing 2-line or 4-line information display capabilities, and equipped with up to 16 programmable function keys and LED indicator lights, supporting multiple communication extensions to meet the demanding needs of different industrial environments.

Product Series Overview

The CP02 series HMI panel is positioned as an entry-level product, but with exceptionally rich functions, inheriting the powerful functional system of the UniOP operator panel family. They support intuitive UniOP Designer 6 programming software, communication drivers for over 130 industrial devices, optional fieldbus modules, dual driver communication capabilities, recipe data storage, multilingual applications, powerful macro editors, alarm management, and eight level password protection, among other core functions.

2.1 Model Classification and Display Types

CP02F-02: Equipped with a vacuum fluorescent display (VFD), displaying 2 lines x 20 characters. VFD technology is known for its high brightness, high contrast, and wide viewing angle, and performs particularly well in low light or industrial environments that require high visibility. The character height is 5mm, and the display is clear and sharp.

CP02R-04: Adopting a monochrome LCD display screen, displaying 4 lines x 20 characters. The backlight is LED, with a typical lifespan of up to 100000 hours. The LCD solution has low power consumption and is suitable for application scenarios that are sensitive to energy consumption or require long-term stable operation. Support software contrast adjustment to adapt to different environmental lighting conditions. Simultaneously supports up to 8 user-defined characters for displaying special symbols or simple graphics.

2.2 Product positioning

The CP02 series is positioned between entry-level and mid-range in the UniOP product line, providing more function keys and stronger expansion capabilities compared to the CP01 series; Compared to higher end graphical HMIs, it maintains the simplicity and economy of the text display interface. This positioning makes it an ideal choice for many cost sensitive but functionally comprehensive industrial control projects.

Detailed explanation of display technology

3.1 Comparison between VFD and LCD Technologies

Vacuum Fluorescent Display (VFD): The VFD technology used in CP02F-02 is a self luminous display device that works similarly to a cathode ray tube, emitting light by electron bombardment of fluorescent powder. VFD has the following outstanding advantages:

High brightness: still clearly visible even in strong ambient light

High contrast: Self luminous characteristics bring excellent contrast performance

Wide viewing angle: a viewing angle close to 180 degrees, suitable for multi angle observation

Quick response: No ghosting, suitable for dynamic data display

Rich colors: usually presented in blue-green or amber, visually comfortable

However, VFDs also have limitations such as relatively high power consumption and inability to display custom characters.

Monochrome LCD: CP02R-04 uses LCD technology to adjust light transmittance by controlling the arrangement of liquid crystal molecules, relying on backlight illumination. Its advantages include:

Low power consumption: suitable for long-term operation and battery powered scenarios

Long lifespan: LED backlight has a lifespan of up to 100000 hours and requires almost no maintenance

Custom Characters: Supports 8 user-defined characters to enhance information expression ability

Software contrast adjustment: adapt to different environmental lighting conditions

3.2 Display Specifications

The character height of both models is 5mm, ensuring good readability at typical operating distances. The 2-line display of CP02F-02 is suitable for displaying key parameters and simple prompts, while the 4-line display of CP02R-04 can present richer information content and reduce page switching frequency.

Human Computer Interaction Design

4.1 Buttons and LED indicator lights

The CP02 series front panel is equipped with a rich system of buttons and indicator lights, providing users with intuitive operation and status feedback mechanisms.

Function keys: Up to 16 user programmable function keys that share key resources with the numeric keypad. Each function key is equipped with a sliding label bar, making it convenient for users to label the current function definition. Through the UniOP Designer software, these buttons can be configured for various operations such as page switching, data writing, alarm confirmation, and recipe calling. The label strip adopts a laser printable design, which is convenient for on-site production and replacement.
