UniOP CP01R-04, CP05R-04, and CP01F-02 Compact Low Cost HMI Devices

UniOP CP01R-04, CP05R-04, and CP01F-02 Compact Low Cost HMI Devices

In the field of industrial automation, the human-machine interface serves as a bridge between operators and control systems, and its performance directly affects production efficiency and operational experience. The UniOP CP series compact HMI devices, with their small size, rich functions, and high cost-effectiveness, have become an ideal choice for many scenarios such as mechanical equipment, process control, and building automation. This series includes three models: CP01R-04, CP05R-04, and CP01F-02, all based on a 20 character display width, providing 2-line or 4-line information display capabilities, and equipped with programmable function keys and LED indicator lights, supporting multiple communication extensions, fully meeting the interaction needs of different industrial environments.

Product Series Overview

The CP series HMI panel is positioned as a compact and low-cost product, but with exceptionally rich functions. They support powerful features common to UniOP operator panels, including intuitive programming software, communication drivers for over 130 industrial devices, optional fieldbus modules, data display and recipe storage, keyboard macro editing, alarm management, and eight level password protection.

2.1 Model Classification and Display Types

CP01F-02: Equipped with a vacuum fluorescent display (VFD), displaying 2 lines x 20 characters. VFD has the advantages of high brightness, high contrast, and wide viewing angle, making it suitable for situations with low light or requiring high visibility.

CP01R-04: Adopting monochrome LCD, displaying 4 rows x 20 characters, backlit with LED, with a lifespan of up to 100000 hours. The LCD solution has low power consumption and is suitable for applications that are sensitive to power consumption or require a longer lifespan.

CP05R-04: Also using monochrome LCD, displaying 4 rows x 20 characters, LED backlight, with a lifespan of 100000 hours. Compared with CP01R-04, CP05R-04 has been streamlined in terms of functionality, such as not supporting dual drive capability and recipe storage, but still retains the core alarm and event list functions.

Detailed explanation of display technology

3.1 Comparison between LCD and VFD

LCD (Liquid Crystal Display): CP01R-04 and CP05R-04 are equipped with a transmissive monochrome LCD, relying on LED backlight. Its character height is 5mm and supports software contrast adjustment (only CP05R-04). LCD can still be read in strong ambient light and has extremely low power consumption, making it suitable for devices powered by batteries or requiring heat dissipation.

VFD (Vacuum Fluorescent Display): CP01F-02 adopts VFD technology, self luminous, high brightness, and the color is usually blue-green or amber, which is very eye-catching in dark environments. VFD has fast response speed and no viewing angle limitation, but its power consumption is relatively high and its lifespan is limited by the aging of fluorescent materials (although it can still reach tens of thousands of hours).

3.2 User defined Characters

CP01R-04 and CP05R-04 support up to 8 user-defined characters, which can be used to display special symbols or simple graphics, enhancing the flexibility of information expression. Due to the use of VFD, CP01F-02 does not support custom characters, but its standard character set is sufficient to meet most text display needs.

Human Computer Interaction Design

4.1 Buttons and LED indicator lights

The CP series front panel is equipped with a variety of buttons and indicator lights, providing users with intuitive operation and status feedback.

Function keys: 5 user programmable function keys (F1~F5), each equipped with a sliding tab for easy labeling of the current function. Through UniOP Designer software, these buttons can be configured for various operations such as page switching, data writing, alarm confirmation, etc.

System keys: There are a total of 19 system keys, including numeric keys, directional keys, confirmation keys, etc., used for data input and menu navigation. The layout of the system keys has been optimized for easy one handed operation.

User LED: 5 programmable LED indicator lights, which may be green or red in color (depending on the model), used to display device status, alarms, or custom signals. Each LED can be configured with software to turn on/off or flash logic.

System LED: 1 dedicated green LED (marked as DL) used to indicate the operating status of the device. Its meaning is as follows:

OFF: No buttons pressed and no errors.

Flashing: Communication error or low battery level.

ON: Provides visual feedback or indicates hardware failure when any button is pressed.

4.2 Label strips and attachments

All function keys support sliding label strips, allowing users to print custom icon labels and quickly identify key functions. Laser printable blank label strips are provided as attachments for easy on-site production.

Memory and Storage

The CP series HMI is equipped with non-volatile memory for storing project files, recipe data, and event logs.

User memory: The standard configuration is 512 KB, which can be expanded to 512 KB (i.e. a total memory of 1 MB). Memory is used to store images, variable definitions, text messages, etc.
