UniOP ePAD32B/ePAD33B/ePAD33BT Industrial HMI

2.4 Power Supply and Electrical

Supply voltage: 24 VDC (typical industrial standard)

Power consumption: Specific values are not provided in the original text, but reference is made to similar products with a power consumption of approximately 15-25W.

Protection level: IP65 front panel (dustproof and waterproof), suitable for humid or dusty environments.

Working temperature: The original text did not provide a detailed range, but universal UniOP products typically range from 0 to 50 ℃, with optional wide temperature models available (specific ordering information needs to be checked).

2.5 Backlight lifespan

The document mentions that 'the lamp lifetime is the typical value for continuous operation at 25 ℃', and the LED backlight lifespan of TFT screens is usually over 50000 hours (approximately 5.7 years of continuous use).

Communication and networking capabilities

3.1 Built in communication port

The ePAD3xB series provides at least one multi protocol PLC port, which can be configured through software as RS-232, RS-422, or RS-485, and supports over 130 industrial communication drivers. In addition, it is equipped with an Aux auxiliary port for connecting optional modules.

3.2 Dual Drive Communication Capability

Similar to ePAD05, the entire series supports Dual driver communication capability, which means HMI can communicate with devices of two different protocols simultaneously. For example, one port is used to connect to a Modbus RTU frequency converter, while the other port (via an Ethernet module) is used for TCP/IP communication with the Siemens S7-1200.

3.3 Optional fieldbus and Ethernet modules

Through the Aux port, users can insert the following optional modules:

Fieldbus modules: Profibus DP, CANopen, DeviceNet, Interbus

Ethernet module: Supports TCP/IP and has the following functions:

Connect PLC or remote I/O with Ethernet interface

Download/upload projects directly from UniOP Designer via Ethernet

Send alarm, event, trend data, and recipe data to the upper computer or SCADA system

Build UniNET network (UniOP HMI data sharing network based on Ethernet, and provide OPC Server)

3.4 Video Input Options (ePAD33B and ePAD33BT only)

This is an important differentiating feature of the ePAD3xB series compared to other UniOP products. Through a dedicated video input module, HMI can receive composite video signals (such as analog outputs from CCTV cameras, industrial endoscopes, and machine vision systems). The video footage can be displayed in real-time within a window on the HMI screen, making it convenient for operators to monitor the equipment's operating status while observing physical processes (such as checking whether the mixing blade is rotating and whether the material is in place). This function has extremely high practical value in fields such as food processing, packaging machinery, and remote inspection.

3.5 UniNET Network

The Server and Client modes that support the UniNET protocol enable data sharing between multiple UniOP HMIs, or exchange data with upper computer software such as Wonderware and WinCC through UniNET OPC Server.

Deep analysis of software functions

The ePAD3xB series uses UniOP Designer 6 software for engineering configuration, with extremely rich software functions that far exceed those of door level products.

4.1 Data Collection and Trend Display

Support displaying analog data (temperature, pressure, flow rate) in the form of real-time trend curves and historical trend curves.

Trend data can be stored in 32MB of user memory and periodically uploaded to the upper computer or database via Ethernet for long-term data analysis.

Multiple curves of different colors can be displayed on the same screen, supporting interactions such as zooming and cursor reading.

4.2 Vector Graphics and Animation

Support vector graphic objects (lines, rectangles, circles, ellipses, polygons) that can be infinitely scaled without distortion.

Support multi-layer graphic overlay and object transparency, achieving semi transparent overlay effect (such as overlaying semi transparent alarm windows on background images).

Dynamic graphic objects can change color, position, size, or visibility based on variable values.

Analog gauge objects make analog display more intuitive, supporting custom scales, pointer colors, and ranges.

4.3 Alarm and Historical Events

Number of alarms: No specific upper limit, determined by memory, usually supporting thousands of alarms.

Historical alarm list: automatically records the occurrence, confirmation, and recovery time of alarms.

Event List: Record operator actions (parameter modification, screen switching) and system events.

Alarm and event information can be sent to remote printers or upper computers via Ethernet.

4.4 Formula Data Storage

Formula data can be stored in 32MB of memory and can be uploaded/downloaded to the upper computer via Ethernet for backup or analysis.

The operator can select the recipe number through the keyboard or touch screen, download it to the PLC with one click, or save the current value of the PLC as the recipe.

4.5 Multilingualism and Unicode

Supports multi language runtime switching, with the number of languages limited only by memory.
