　　ETOP20C0050 Other Names:

　　HMI Touch Screen ETOP20C0050

　　ETOP20C0050 Operator Interface

　　Human-Machine Interface ETOP20C0050

　　UNIOP ETOP20C0050 is an industrial human-machine interface (HMI) panel manufactured by UNIOP (now part of ESA Automation Group) in Italy. It is widely used in the automation control field.

　　Main Functions

　　Visual Monitoring

　　Real-time display of device status, parameters, alarm information, etc.

　　Supports data visualization such as dynamic graphics, trend charts, and bar charts.

　　Operation Control

　　The device starts and stops, sets parameters, switches modes, and more through the touchscreen or keypad.

　　Supports multi-level menus and permission management (e.g., operator/engineer permissions).

　　Data Logging and Alarms

　　Built-in data logging allows for storage of historical data or event logs.

　　Supports customizable alarm thresholds and notifications (sound, light, email, etc.).

　　Communication Protocol Support

　　Compatible with a variety of industrial protocols, including Modbus RTU/TCP, Profibus DP, and CANopen.

　　Seamlessly connects with PLCs, inverters, sensors, and other devices.

　　Core Parameters and Features

　　Display

　　Size: 5.7 inches (diagonal), suitable for space-constrained industrial scenarios.

　　Type: STN (super twisted nematic) LCD, supports monochrome display (typically blue/white or yellow/green backlight).

　　Resolution: 320×240 pixels, meeting basic monitoring needs.

　　Backlight Lifespan: ≥50,000 hours (LED backlight), reducing replacement frequency.

　　Processor and Memory

　　CPU: 32-bit RISC processor, clocked at approximately 200MHz, ensuring smooth operation.

　　Memory:

　　Flash: 4MB (for program and data storage).

　　RAM: 2MB (for temporary tasks).

　　Storage Expansion: Supports CF cards (up to 2GB) for program backup or data logging.

　　Communication Interfaces

　　Serial Port: 1 RS232/RS485 switchable port, compatible with Modbus RTU and UNIOP protocols.

　　Ethernet: Optional (check the model suffix, e.g., ETOP20C0050-ET), supports Modbus TCP/IP.

　　USB: 1 USB 1.1 port for program downloads or data export.

　　Input/Output

　　Touch Screen: 4-wire resistive, glove-compatible, and highly durable.

　　Buttons: No physical buttons (pure touch design), simplifying cleaning and maintenance.

　　LED Indicators: Indicates power status and communication activity.

　　Electrical Parameters

　　Power Supply: DC 24V (±20%), Power Consumption: Approximately 8W (typical).

　　Insulation Class: Complies with IEC 61131-2, withstand voltage 1500V AC (1 minute).

　　Protection Rating: IP65 (front panel), dustproof and waterproof, suitable for harsh environments.

　　Mechanical Parameters

　　Dimensions: 165 × 125 × 45 mm (W × H × D), compact design saves space.

　　Weight: Approximately 0.6 kg, easy to install.

　　Mounting Method: Panel-mounted (cutout dimensions 157 × 117 mm) or bracket-mounted.

　　Typical Applications

　　Control of small automated equipment

　　Packaging machines, labeling machines, small CNC machine tools, etc., for start/stop, parameter setting, and status monitoring.

　　Example: Monitoring parameters such as packaging speed and temperature on a food packaging line.

　　Building Automation

　　Providing a local operation interface for air conditioning systems, elevator controls, lighting management, etc.

　　Example: Displaying floor, travel direction, and fault codes in an elevator control cabinet.

　　Energy Management

　　Monitoring voltage, current, and energy efficiency for solar inverters and UPSs.

　　Example: Displaying data such as power generation and system efficiency in a photovoltaic power plant.

　　Process Control

　　Displaying process parameters such as pressure, flow, and temperature in water treatment and chemical reactors.

　　Example: Monitoring pump status and liquid levels in a sewage treatment plant.

　　Software Support and Development

　　Programming Environment

　　UNIOP eBuilder: Dedicated configuration software supporting Windows XP/7/10 (32/64-bit).

　　Functions:

　　Graphical interface design (buttons, dashboards, trend charts, etc.).

　　Logic programming (similar to ladder diagrams or function block diagrams).

　　Database management (recipes, alarm logs).

　　Multi-language support (Chinese, English, etc.).

　　Communication protocols

　　Standard protocols: Modbus RTU/TCP, UNIOP.

　　Third-party protocols: Drivers are available for Siemens S7, Omron, Mitsubishi, and other PLCs.

　　OPC compatibility: Integration with SCADA systems is possible via the OPC Server.

　　Development steps

　　Install eBuilder software and create a new project.

　　Design the interface (add buttons, text boxes, trend charts, and other elements).

　　Configure communication parameters (PLC model, serial port/Ethernet settings).

　　Write logic (e.g., a button triggers a write to a PLC register).

　　Download the program to the ETOP20C0050 (via USB or serial port).

　　On-site debugging and optimization.

　　Maintenance and troubleshooting

　　Daily maintenance

　　Cleaning: Wipe the touch screen with a dry cloth; avoid using alcohol or chemical solvents.

　　Backup: Regularly back up the program to a CF card or computer.

　　Check: Verify that the backlight is functioning properly and the communication indicator is flashing.

　　Common Faults and Solutions

　　Touchscreen Unresponsive:

　　Check that the power supply is functioning properly (DC 24V).

　　Recalibrate the touchscreen (using eBuilder software).

　　Communication Interruption:

　　Check if the serial/Ethernet cable is loose.

　　Confirm that the PLC address and baud rate are set correctly.

　　Black Screen:

　　Check if the backlight is damaged (display needs to be replaced).

　　Confirm that the power input is stable (avoid voltage fluctuations).
