Dynamic data presentation: supports multiple dynamic data formats such as numerical values, text, bar charts, sliders, dashboards, and graphic images. Supports bitmap, JPEG, and dynamic GIF images, making visual design more impactful.
Visual object properties: The visibility, position, and other properties of an object can be dynamically controlled to meet the UI feedback requirements of complex logic.
Macro instructions and scripts: Built in easy-to-use scripting language editor, macro commands can be triggered by touch screen buttons, system events, or timers to achieve complex logical operations and data processing.
Core functions: data collection, formulation, and alarm management
In actual production and building management, data traceability and alarm processing are core necessities. The eV058 series performs very comprehensively in this regard:
Data collection and trend chart: The panel supports historical data collection and displays it in the form of trend charts, and trend data can be transferred to the upper computer to provide data support for equipment fault diagnosis and energy efficiency analysis.
Formula data storage: Supports formula management function, and formula data can also be exported to the upper computer. In scenarios such as food processing and chemical ingredients that require frequent switching of process parameters, this feature greatly reduces manual input errors.
Alarm and Event Management: Supports real-time alarm and historical alarm log functions. Alarm and event information can be directly output through a printer or transferred to the host computer via serial port/Ethernet. Combined with multi-level password protection function, operators with different permissions can only access their corresponding alarm confirmation, parameter modification and other operations, ensuring the data security of the system.
On site installation, wiring, and troubleshooting guide
In industrial sites, the stable operation of HMI depends not only on the product itself, but also on correct installation and wiring. For eV058-TST/TNT, engineers need to focus on the following points:
Power and grounding: A DC power supply that meets specifications (usually 24V DC) must be used, and the panel must be well grounded to suppress electromagnetic interference (EMI), prevent touch screen drift or communication interruption.
Serial communication wiring (COM1/COM2): When communicating over long distances with RS-485 or RS-422, it is necessary to use twisted pair shielded wires and connect matching terminal resistors at the end devices of the bus. Pay attention to distinguishing the pin definitions of COM1 and COM2 (especially the switching of COM2 between RS-232 and RS-422/485), as wiring errors are a common cause of communication failure.
Ethernet communication (TNT only): It is recommended to use industrial grade shielded Ethernet cables and ensure that the IP address of the HMI device is on the same network segment as other devices in the local area network. If packet loss is severe, the network switch should be checked for broadcast storms, or a direct test using a crossover connection should be attempted.
Touch screen calibration and battery replacement: If the touch position is found to be offset, it can be recalibrated by entering the calibration interface through the system settings (if the system menu is configured). When the panel frequently experiences time reset or historical data loss, it is necessary to consider replacing the RTC backup battery on the motherboard.
Environment and Protection: Although the panel is panel mounted, in dusty or humid environments, it is necessary to ensure that the sealing gasket between the panel and the cabinet opening is installed in place, and follow the installation depth and opening size specifications provided by the panel to prevent liquid infiltration and internal circuit short circuits.
