Connect any Modbus-enabled PLC to a live web dashboard. Monitor registers, set alarms, view historical trends — from PC, tablet, or phone, no workstation software needed.
60-day free trial · All features included · No credit card
From first register read to full production monitoring in minutes
Build HMI-style dashboards showing live PLC register values. Gauges, bar charts, digital displays, status indicators — no programming, just point-and-click configuration.
Set high/low/deviation alarms on any PLC register. Email alerts sent to operators and maintenance teams. Acknowledge, shelve, and audit alarms with full history.
Every PLC tag logged continuously. Query any time range, zoom in on incidents, export to CSV for analysis. Ideal for OEE tracking and predictive maintenance.
Edge connector uses outbound HTTPS only. Your PLC network stays private. TLS encryption throughout. Role-based access with full audit log of every change.
Monitor entire production lines across multiple PLCs and sites from one dashboard. Mix TCP and RTU PLCs. Unlimited devices on the 60-day trial.
Open on any PC, phone, or tablet. Share read-only dashboards with management. No app to install — works on Chrome, Edge, Firefox, Safari.
Download the lightweight edge connector to a PC on your plant network. It polls your PLC Modbus registers and forwards data securely to SCADA Cloud over HTTPS.
In the browser interface, define each PLC register as a tag: IP address or COM port, Modbus function code (FC01-FC04), register address, data type (INT, FLOAT, BOOL), and engineering unit.
Open your dashboard URL. Share with your team. Set alarm thresholds. View trends back 30, 90, or 365 days. Access from any browser on any device.

CLICK PLC, AutomationDirect, Unitronics, Koyo, and any Modbus-compliant PLC.
Traditional PLC monitoring software — Wonderware InTouch, Ignition, FactoryTalk View — requires on-premise SCADA servers, Windows workstations, and expensive per-client licences. For small to mid-size plants, the infrastructure cost often exceeds the monitoring value.
SCADA Cloud eliminates all of that. The only on-site component is the edge connector — a lightweight process that runs on any Windows, Linux, or Raspberry Pi machine on your plant network. It polls your PLC Modbus registers at 1-second intervals and forwards data to SCADA Cloud over HTTPS. No servers to manage, no IT team required.
Engineers get live PLC dashboards from day one. Add tags, build HMI screens, configure alarms — all from a browser. When shift changes, the next operator opens the same dashboard URL on their PC. Management views real-time production KPIs on their phone. Remote service engineers diagnose faults from home without VPN.
The Modbus slave simulator integrates directly with this workflow: simulate your PLC's register map during design, validate SCADA tags and alarm thresholds before commissioning, then switch to the real PLC. Also see Modbus TCP simulator for TCP-specific testing.
PLC monitoring software reads live data from PLCs and displays it as dashboards, alarms, and trends. SCADA Cloud is browser-based PLC monitoring — no workstation software, no SCADA server. A small edge connector reads your Modbus PLC registers and SCADA Cloud visualizes the data from any browser.
Any PLC with Modbus TCP or Modbus RTU communication — Siemens S7-1200/1500, Allen-Bradley Micro820/850, Schneider Modicon M221/M241, Delta DVP/AS series, Mitsubishi FX5U, and hundreds of others. If your PLC has a Modbus TCP server or RTU port, SCADA Cloud can monitor it.
No. SCADA Cloud is entirely browser-based. Operators open a URL in any browser — Chrome, Edge, Firefox, Safari — and see live PLC data. No client software, no Java, no plugins. Only the edge connector runs locally, and that runs on one PC or Raspberry Pi per site.
Yes. Unlimited PLCs per account. Tags from multiple PLCs appear side by side on the same dashboard. Monitor an entire production line — conveyor PLC, press PLC, packaging PLC — from one browser screen.
Use ModbusSimulator's slave simulator desktop app to emulate your PLC's register map. Configure the same function codes and addresses. Connect SCADA Cloud to the simulator, validate tags and alarms, then switch to the real PLC IP. Zero reconfiguration needed.
