Read Modbus registers directly from your PLCs and display live gauges, trend charts, and KPI dashboards in any browser. No SCADA licence fees. No on-premise servers.
60-day free trial · All features included · No credit card required
Reading raw register values from PLCs is just data — visualization turns it into understanding. Time-series charts, gauges, alarm panels, and custom dashboards let engineers see process state at a glance, spot trends before they become problems, and share real-time status with anyone on the team.
Traditionally this required expensive SCADA licences, dedicated operator workstations, and complex on-premise software that took weeks to configure. Cloud-based PLC data visualization changes that. Connect your PLC over Modbus TCP, map registers to widgets, and your dashboard is live in minutes — accessible from any browser, on any device.
SCADA Cloud by ModbusSimulator is built specifically for engineers who want the visualization power of a traditional SCADA system without the cost, complexity, or infrastructure overhead. It reads directly from Modbus TCP/RTU devices and turns holding registers, input registers, and coils into meaningful visual representations your whole team can understand.
Everything you need to go from raw register values to actionable dashboards
Map any Modbus holding register or input register to a live gauge widget. Set min/max scale, engineering units, and color zones. Watch process values update in real time as your PLC reports them.
Every tag is automatically logged. View any time range — last hour, last week, last year. Overlay multiple registers on a single chart to compare motor current, temperature, and pressure trends side by side.
Drag-and-drop designer lets you arrange gauges, charts, value boxes, and status indicators on a canvas. Build separate dashboard views for operators, engineers, and managers — each tailored to what they need to see.
Set High, High-High, Low, and Low-Low thresholds on any visualized tag. Widgets change color automatically (yellow for warning, red for alarm) and email notifications fire when limits are crossed.
Add multiple PLCs or Modbus devices to a single dashboard. Compare registers from different machines or production lines on one screen — essential for multi-line or multi-site monitoring.
Export any historical trend to CSV for further analysis in Excel or Python. Generate PDF reports of dashboard snapshots for shift handovers, maintenance records, or management reporting.
Enter your PLC's IP address and port for Modbus TCP, or configure a serial gateway for Modbus RTU. The platform starts polling your device automatically — no programming required.
Select holding registers, input registers, or coils and assign them to visual widgets: gauge, trend chart, value box, or status indicator. Set engineering units, scale factors, and alarm thresholds.
Arrange your widgets on the dashboard canvas and share the link with your team. Operators, engineers, and managers can all see the same live data from any device — no software to install.
PLC data visualization in practice — across sectors
Read power meter registers (kWh, kW, voltage, current, power factor) and display them as KPI tiles and daily trend charts. Track consumption against targets and spot demand spikes instantly.
Visualize tank level registers as live fill gauges with high/low alarm bands. Trend flow meter values over a shift to catch slow leaks. Monitor pump status coils as color-coded indicators on a site overview.
Display production counter registers as live KPI numbers with shift totals. Trend machine cycle time to catch performance degradation early. Compare output rates across multiple production lines side by side.
Plot temperature registers from rooftop units, AHUs, and zones on a 24-hour trend. Set setpoint deviation alarms so maintenance is notified before occupant comfort is affected.
Modbus TCP/IP and Modbus RTU via serial-to-Ethernet converter. Additional OPC UA and MQTT support planned. Any PLC or device with a Modbus register map works — Siemens, Allen-Bradley, Schneider, Delta, FATEK.
Yes. The dashboard builder supports drag-and-drop widget placement. You can create separate dashboard views for operators (simple gauges), engineers (trend charts + raw values), and managers (KPI summary). Each view can be shared via a unique link.
Default polling interval is 1 second for Modbus TCP and 2 seconds for Modbus RTU (to account for serial turnaround). You can configure per-tag polling intervals from 500ms to 60 seconds depending on how fast your process changes.
Yes. Each tag supports High, High-High, Low, and Low-Low threshold alarms. When a register value crosses a threshold, the widget changes color (yellow for warning, red for alarm) and an email notification is sent. Alarm history is stored for 90 days.
Simulate any Modbus device on your PC to test your SCADA and visualization setup without real hardware.
Test your Modbus TCP connections and polling logic before connecting live PLC hardware.
Real-time PLC monitoring over Modbus with alarms, trends, and remote access from any browser.
Full SCADA functionality for Modbus TCP and RTU devices — dashboards, alarms, logging, and reporting.
Browser-based SCADA for industrial monitoring — no server to install, access from anywhere.
Hosted SCADA as a service — connect Modbus, MQTT and OPC UA devices to a managed cloud platform.
Connect your first Modbus device and build a live dashboard in under 10 minutes. 60-day free trial — no credit card, no hardware required.
