LED DNL digital display panels are designed for display of digital values indoor: offices, manufacturing plants or production supervision points, providing information such as production parameters, machine condition, device operational status etc.
DNL display panels can be configured with LPCon software application available for free on the website www.lumel.com.pl. DNL display panels are equipped with two RS485 communication interfaces using MODBUS RTU standard. First interface (programming interface) is used for the configuration of the display panel settings or for the input of displayed value (the display panel is a Slave device in MODBUS RTU network) e.g. from the SCADA application or PLC drivers Second interface (object interface) is used for plugging slave devices (the display panel is a Master device in MODBUS RTU network) the display panel gets displayed data from. Display panel configuration allows reading up to 100 registers from slave devices (up to 10 registers per each of 10 devices), so the display panel can act as the local data collection point. All data received from slave devices can be accessed as internal registers of the display panel for the SCADA application or PLC drivers via RS485 MODBUS RTU Slave interface. It is possible to define minimum and maximum displayed value for the display panels. Additionally, the display panel may be equipped with auxiliary measurement input for the measuring of standard analog signal 4..20 mA used in automatics and with output powering external measurement transducers. Basic configuration of the display panel includes one or two fields for readings (4 digits each) and space for the unit placement.
