Exor Modbus Marquee Series

The Datavisor Modbus Marquee Series (distributed through EXOR Electronic R&D) is a line of industrial-grade LED display signs that communicate natively over the Modbus TCP network. Each unit includes an embedded web server and a second dedicated Ethernet port for simultaneous data collection to a PC — without installing any software or modifying PLC ladder logic.

Messages displayed on the marquee are drawn directly from internal PLC registers. Register data can be any combination of bits, words, or strings — covering alarms, machine performance metrics, and production data. The second Ethernet port broadcasts that same information to any computer on the plant network via the built-in web server, and third-party spreadsheets can be used to monitor and store it.

These displays are used in manufacturing facilities running Modbus TCP networks where operators and supervisors need direct, real-time visibility of PLC data without programming communication blocks in ladder logic. Typical applications include:

• Production goal vs. actual count display
• Machine efficiency and OEE metrics from PLC registers
• Alarm and fault condition broadcasts from Modbus controllers
• Job completion percentage and quality data
• Real-time data collection to PC or third-party spreadsheets

• No software to install — web-based setup via embedded server
• Modbus TCP protocol — direct register access from PLC without ladder logic changes
• Direct register access to PLC from the marquee sign
• Second dedicated Ethernet port for simultaneous data collection to PC
• Monitor PLC registers through the built-in web browser
• Broadcast alarm messages directly from the PLC
• Backup and restore marquee configuration via browser
• Collection of real-time data from plant floor
• IR programming port for hand-held configuration
• Mounting hardware included

The Modbus Marquee includes a browser-based interface accessible by entering the unit's IP address. No credentials are required to view the monitor page; configuration access requires authorization.

Monitor Page — displays all user-configured process values and variable data in real time. Changes can be applied without leaving the browser.

Setup Menu — provides access to eight configuration sections:

• Edit Marquee Messages
• PLC Communication Settings
• Configure Network
• Time/Date Setup
• Variable Data Configuration
• Variable Color Configuration
• Text List Configuration
• Backup/Restore Configuration

Message Edit Page — set message text, font size, color, flash behavior, and minimum display time for up to 100 messages across paginated groups.

Variable Data Configuration — define which PLC register data appears on the marquee, including data description, precision, format, justification, color, and monitor display toggle for each variable.
