Connect Modbus TCP and RTU devices and turn register values into real-time gauges, trend charts, and alarm tables — accessible from any browser, no server required.

A Modbus dashboard is a visual interface that reads values from Modbus TCP or RTU devices and displays them as real-time gauges, charts, value tiles, and status indicators — all accessible from a web browser. Instead of opening a Modbus polling tool and reading raw hexadecimal register values, engineers and plant operators see meaningful, live data: temperature readings, pressure values, motor speeds, energy consumption, and alarm states.
Modbus dashboards serve as the front-end visualization layer for industrial monitoring. They bridge the gap between raw Modbus device data and actionable, human-readable plant visibility. For PLCs, energy meters, VFDs, sensors, and flow controllers that speak Modbus, a dashboard turns their register maps into live operational intelligence.
SCADA Cloud provides a browser-based Modbus dashboard platform. You connect your Modbus TCP devices directly (enter IP and port) or configure Modbus RTU via a serial gateway, define which registers to poll, and build your dashboard by dragging widgets onto a canvas. The platform handles polling, data logging, alarm evaluation, and dashboard delivery to any browser — no server infrastructure required on your end.
Unlike desktop Modbus tools that only display raw values in tables, SCADA Cloud's Modbus dashboard supports engineering unit scaling, custom alarm thresholds, historical trending, and multi-device views — giving you the full picture of plant operations from a single URL.
Poll any Modbus register at configurable intervals. Display the live value as a number, gauge, progress bar, or status indicator. Auto-refresh with no page reload required.
Every register value is automatically logged. View trends over hours, days, or weeks with interactive charts. Zoom in on incidents, export data for reports, or identify slow drift before it becomes a fault.
Configure high and low alarm thresholds per register. Receive in-browser notifications and optional email alerts when values exceed your defined limits. Active alarms show on the dashboard in real time.
Apply linear scaling to convert raw register counts to engineering units. Map 0–4095 to 0–100 bar, or 6553–32768 to 4–20 mA equivalents. Display values in °C, bar, kWh, RPM, or any unit you define.
Add multiple Modbus TCP or RTU devices and display registers from all of them on a single dashboard canvas. Monitor a PLC, energy meter, and VFD side by side — each polled independently and concurrently.
Your Modbus dashboard is accessible from any browser — PC, Mac, tablet, or phone. Share the dashboard URL with maintenance engineers, plant managers, or remote teams. No software to install on any client device.
SCADA Cloud dashboards support all four standard Modbus data tables
| Register Type | Function Code | Access | Typical Use |
|---|---|---|---|
| Holding Registers | FC03 | Read / Write | Setpoints, process values, configuration parameters |
| Input Registers | FC04 | Read only | Sensor measurements, analog inputs, counters |
| Coils | FC01 | Read / Write | Digital outputs, relay states, control bits |
| Discrete Inputs | FC02 | Read only | Digital inputs, limit switches, fault flags |
For Modbus TCP: enter the device IP address and port (default 502). For Modbus RTU: configure your serial-to-Ethernet gateway with its IP. SCADA Cloud sends the first poll request immediately and confirms connectivity.
Add tags for each register you want to monitor. Specify function code (FC01–FC04), register address, data type (INT16, UINT16, FLOAT32, etc.), and optional scaling and alarm limits. Give each tag a descriptive name.
Drag widgets — gauges, value tiles, trend charts, alarm banners — onto your canvas. Assign each widget to a tag. Save and share the live dashboard URL with anyone who needs visibility. Updates automatically as register values change.
Register at scada.modbussimulator.com/register. Add your Modbus TCP device (IP and port 502) or configure a Modbus RTU serial gateway. Define which registers to poll — specify function code (FC03 for holding registers, FC04 for input registers), starting address, and data type. Then drag dashboard widgets onto your canvas — gauges, value displays, trend charts. The dashboard updates live. Most users have a working dashboard within 20–30 minutes of signing up.
Yes. SCADA Cloud reads Modbus TCP and RTU devices on your network and displays register values in a browser-based dashboard. Access your Modbus dashboard at scada.modbussimulator.com from any PC, tablet, or smartphone — no software installed locally. The platform polls your devices at configurable intervals (1 second to 60 seconds) and updates the dashboard in real time. All four Modbus data tables are supported: holding registers, input registers, coils, and discrete inputs.
All four standard types: Holding Registers (FC03, read/write), Input Registers (FC04, read-only), Coils (FC01, read/write boolean), and Discrete Inputs (FC02, read-only boolean). You can mix register types from the same device on one dashboard — for example, showing a temperature value from a holding register alongside a pump run status from a coil and a fault flag from a discrete input.
Yes. SCADA Cloud supports multiple Modbus devices on a single dashboard. Add each device with its IP, port, and Unit ID. Define the registers from each device, then place all widgets on the same canvas. One dashboard can show live data from a PLC, energy meter, VFD, and temperature controller simultaneously — each polling concurrently. There is no hard limit on the number of devices per dashboard within your subscription plan.
Connect your first Modbus device and visualize live register values in minutes. No server, no software install, no credit card required.
