Full SCADA Cloud access for 60 days. Dashboards, alarms, historical trends, Modbus TCP/RTU, MQTT and OPC UA. Start in under 10 minutes.
No feature restrictions. No device limits. No hidden catches. You get the same platform paid subscribers use — every feature, from day one, for 60 full days.
The scada software free trial from ModbusSimulator is designed for engineers who want to evaluate a real industrial monitoring platform against real plant conditions — not a stripped-down demo. You can connect actual Modbus TCP devices from your network, configure live tags, build dashboards, and set alarm thresholds before spending a single dollar. Most engineers have a working dashboard within 10 minutes of registration.
The trial covers Modbus TCP direct connections to Ethernet PLCs, energy meters and VFDs; Modbus RTU over RS-485 serial lines via the lightweight edge connector; MQTT subscriptions to any broker topic; and OPC UA client connections to modern PLCs. There is no per-device limit, no per-tag limit, and no restriction on the number of dashboards you can create during the trial period.
For small installations — a single site with fewer than five connected devices — SCADA Cloud remains free forever with the basic plan. The 60-day trial lets you evaluate the full platform, including multi-site support, role-based access control, advanced alarm escalations, and CSV data exports, before you decide whether to upgrade.
Everything a traditional SCADA server provides, delivered as SaaS from any browser.
Live dashboards update every second. View gauges, trend charts, and digital values exactly as you would on a traditional HMI — from any browser on any device, with no VPN needed.
Direct connection to any Modbus-enabled PLC, energy meter, VFD, or sensor. TCP over Ethernet; RTU over RS-485 serial via the lightweight edge connector. No middleware required.
Connect to any MQTT broker or OPC UA server. Perfect for IIoT gateway data, modern PLCs (Siemens S7, Beckhoff, Codesys), and cloud-native sensor networks.
Threshold alarms on every tag. Route to email or SMS. Acknowledge and silence from any device. Full alarm history with timestamps, operator notes, and audit log for compliance.
Cloud historian stores every data point automatically. Query 30 days of trends for root-cause analysis, compliance reporting, or performance benchmarking — without touching a server.
Monitor multiple plants, buildings or substations from a single login. Role-based access control (Admin, Operator, Viewer) keeps teams focused on their own sites and data.
Create a free account at scada.modbussimulator.com/register. Email only — no payment details, no credit card. Your 60-day scada software free trial starts immediately after email confirmation.
Download the lightweight edge connector (<20MB) and run it on any Windows PC or Raspberry Pi on your local network. Configure your Modbus TCP/RTU, MQTT or OPC UA connection. No firewall changes needed.
Map tags in the browser-based editor. Drag gauges, charts and value displays onto your dashboard canvas. Your live plant data appears within seconds. Total time from registration to live data: under 10 minutes.
Traditional SCADA platforms like Ignition, WinCC, and iFIX require a dedicated Windows server, per-workstation client licenses, a SCADA integrator for configuration, and typically several weeks of implementation before the first live dashboard appears. The total cost of a mid-size traditional SCADA installation — hardware, licenses, integration services — routinely exceeds $50,000 before a single tag is live.
SCADA Cloud eliminates every one of those barriers. There is no server to rack and maintain. There is no client software to install on engineer workstations. There is no per-seat licensing. The edge connector takes five minutes to deploy on any existing PC on the plant network. The scada software free trial starts the moment you confirm your email, and you are looking at live Modbus data within 10 minutes.
This is also why SCADA Cloud is the right retrofit solution for plants that already have PLCs and HMIs but lack a historian and centralised alarms. Your existing Modbus TCP/RTU devices keep running unchanged. SCADA Cloud reads the same registers in parallel — no PLC changes, no HMI changes, no downtime. You get the full SCADA historian and alarm layer added on top of your existing automation without a costly integration project.

Full access to all features: unlimited devices, unlimited dashboards, alarm management with email notifications, historical trends stored in the cloud historian, Modbus TCP/RTU, MQTT broker, and OPC UA client. There are no feature restrictions during the 60-day trial period — you get exactly what paid subscribers use.
No. Register with your email at scada.modbussimulator.com/register. No payment details required. The 60-day trial begins immediately after email confirmation. There are no automatic charges when the trial ends.
No server installation required. SCADA Cloud is hosted in the cloud and accessed from any web browser. You install only a small edge connector (<20MB) on a local PC or Raspberry Pi that bridges your field devices to the cloud. The edge connector initiates outbound connections only — no inbound firewall ports needed.
You choose whether to continue with a paid subscription. Your dashboards, tags, and historical data are preserved. Without a subscription, the account enters read-only mode — no new data is collected until a plan is added. There are no automatic charges and no data is deleted.
Modbus TCP (Ethernet PLCs and meters), Modbus RTU (serial RS-485 devices via edge connector), MQTT (any broker), and OPC UA client connections. These four protocols cover the vast majority of industrial devices sold today and let you connect any Modbus device in your plant without additional gateways or middleware.
Simulate Modbus RTU/TCP slave devices on Windows. Use alongside SCADA Cloud to test your dashboards before connecting real hardware.
Run a Modbus TCP server on your PC to simulate live register data. Connect to SCADA Cloud to build and test dashboards without hardware.
