In the field of industrial automation and human-computer interaction, the intuitiveness, stability, and functionality of the operating interface directly affect production efficiency and the flexibility of system integration. ECT-16, as a powerful and cost-effective graphical touchscreen human-machine interface, has become an ideal choice in many industrial control scenarios due to its comprehensive functional modules and flexible system adaptation capabilities. This article will provide a comprehensive and in-depth technical analysis of ECT-16 from multiple dimensions, including display characteristics, data interaction, alarm management, network communication, and hardware specifications.
Display System and Graphics Capability
ECT-16 adopts a 16 line x40 character STN passive color LCD display screen with a resolution of 320x240 pixels, supports pixel level addressing, and has graphic drawing capabilities. Through UniOP Designer for Windows software, users can customize the display interface and achieve rich graphical expression. Each page can display up to 16 lines, with a maximum of 40 characters per line, suitable for displaying a large amount of text and data information. The display screen supports brightness adjustment to ensure good readability under different lighting conditions.
The device also supports bitmap graphics display in BMP format, and users can use Windows based graphic design tools to create icons, flowcharts, or status indicators, greatly enhancing the customizability and visual expression of the interface.
Data Display and Variable Management
ECT-16 is capable of real-time display of variable data within the PLC, with display content not limited by quantity but only by screen size. Supports multiple data formats, including decimal, hexadecimal, floating-point, binary, string, date, and time. The system has a built-in linear transformation function, which can scale the raw data and ultimately present it in the form of bar charts, numerical values, or text. Each data input field can be set with valid range validation to ensure the accuracy of input data and the security of system operation.

Data input and touch interaction
The device is equipped with an analog resistive touch screen, and the touch unit can be flexibly defined, with a minimum size of a single character and a maximum coverage of the entire screen. Users can perform various operations such as page switching, data writing, alarm viewing, recipe uploading and downloading through the touch unit. Combined with the keyboard macro editor, users can customize touch functions, reduce the programming burden of PLC, and improve system response efficiency.
Real time clock and time management
ECT-16 has a built-in battery powered real-time clock that supports continuous tracking of time and date. This clock can regularly update the time information in the PLC and support automated control logic based on the time dimension, such as timed start, timed alarm, shift switching, and other functions.
safety mechanism
The system provides an eight level password protection mechanism, allowing users to set different levels of access control based on their permissions to prevent unauthorized operations or configuration modifications. This function is of great significance for protecting key parameters, preventing misoperation, and maintaining system integrity.
Alarm system
ECT-16 supports the definition and monitoring of up to 1024 priority alarms. Each alarm can be configured with independent attributes and prompt information, and can require the operator to confirm. Maintain a historical event list within the system, which can record up to 256 recent alarm events. This list supports screen viewing or output through a serial printer for easy post analysis and tracking.
Recipe Management
The recipe function supports configuration of up to 255 parameter sets per page. The system reserves 16KB of storage space for storing recipe data. Users can upload the formula parameter set to ECT-16 or download it to PLC, and modify the parameters after downloading. This function is particularly practical in multi variety and small batch production scenarios, as it can quickly switch production parameters and improve line changing efficiency.
Network Communication and System Integration
ECT-16 supports UniNET network protocol and can build multiple network topologies, including complex configurations such as single PLC to single panel and multiple PLCs to multiple panels. Through UniNET, users can access data from multiple PLCs simultaneously, enabling cross device information sharing and centralized control, and supporting interconnectivity between PLCs of different brands and models.
Communication interface
The equipment is equipped with multiple communication interfaces to meet the needs of different industrial environments:
A RS-232/RS-422/RS-485/20mA current loop serial port, supporting a maximum communication rate of 38400 bps, used for direct connection to PLC.
An RS-232 port used to connect to a PC or serial printer.
