EC: ViewMarq Industrial LED Message Display
Hardware - HMI, operator interface, thin-client: ViewMarq industrial-grade LED message displays utilize the latest LED and communications technologies to help communicate important information in industrial environments. This is a Control Engineering 2014 Engineers’ Choice finalist.
ViewMarq industrial-grade LED message displays, utilize the latest LED and communications technologies to help communicate important information in industrial environments.
Used to display preformatted messages or factory floor data, the displays can be controlled from a PLC or any device that uses supported protocols. Embedded data support allows real-time production data from the controller to be contained within messages.
ViewMarq supports embedded string and numeric variables, as well as blinking text and scrolling messages. They feature tri-color LEDs and are available in six models: 1 line x 12 character, 2 lines x 12 character, 4 lines x 12 character, 1 line x 24 character, 2 lines x 24 character, and 4 lines x 24 character.
The rugged industrial design features heavy-duty extruded aluminum housings with durable polycarbonate end caps and a smoked polycarbonate lens cover. Access covers with seal-tight cable glands offer reliable, easy installation of power and communication wiring. The displays are NEMA 4 and NEMA 12 (indoor only) rated and withstand washdown conditions.
Displays have 140-degree viewing angles, mount in any horizontal position, and can be wired for 100-240 Vac or 24 Vdc power. Each unit is equipped with an accelerometer to ensure messages automatically display in the upright position.
ViewMarq message displays feature (1) RS-232, (1) RS-485, and (1) Ethernet port, and can be connected to a PLC, PC, or any device capable of serial ASCII master, Modbus RTU, or Modbus TCP communications; all displays are UL 508 listed, CE, RoHS, and REACH compliant.
ViewMarq Configuration Software (free download from the AutomationDirect site) provides multiple functionality; users can create and preview messages in the simulator window on a PC, send the message to the ViewMarq LED display, configure the display to communicate with a PLC, and create ASCII string commands to be used in the PLC program.
