Monitor Modbus PLCs at any site from any browser. No VPN. No SCADA server. Live data, alarms, and trends — accessible on PC, tablet, or phone from anywhere in the world.
60-day free trial · All features included · No credit card
Designed for Modbus environments — not generic IoT platforms
View live PLC register values from any location. Gauge widgets, trend charts, status displays, and digital values — fully configurable, no code required.
Email alerts when any Modbus tag exceeds a threshold. Get notified of PLC faults, high temperature, low pressure, or any register change — wherever you are.
Access up to 12 months of historical tag data from anywhere. Query time ranges, overlay trends, and export CSV — all from a browser without site access.
Outbound HTTPS only from your plant network. No exposed IP addresses, no firewall exceptions, no VPN to configure. TLS encryption everywhere.
Monitor PLCs across all your remote sites from one account. Water pumping stations, solar farms, oil wellheads — all visible from one browser dashboard.
Fully responsive dashboards. Check plant status from your phone while traveling. Receive alarm emails and acknowledge on mobile without going to site.
Install the edge connector on any PC at your plant — Windows, Linux, or Raspberry Pi. It reads Modbus registers locally and securely forwards data outbound. No firewall changes needed.
From any browser, define PLC tags (Modbus address, data type, unit) and alarm thresholds. Set email recipients. Build your dashboard with drag-and-drop widgets.
Open your dashboard URL from any PC, phone, or tablet anywhere in the world. No VPN, no special software. Share read-only access with management or customers.
Monitor power distribution, breaker status, and energy readings at remote electrical substations. Alarm on fault conditions without a full-time operator on-site.
Monitor pump stations, tank levels, flow rates, and treatment process readings remotely. Multi-site visibility from one dashboard for utilities managing many lift stations.
Read inverter Modbus registers — power generation, fault codes, string data — at remote solar sites. Alarm on underperformance before it affects revenue.
Central manufacturing monitoring across multiple plants. Production managers view OEE, cycle counts, and fault rates from headquarters without VPN to each factory.
Monitor HVAC PLCs, chiller systems, and building management controllers remotely. Facilities managers check equipment status from anywhere.
Wellhead PLC monitoring without field technician visits. Read pressure, flow, and pump status remotely. Alert on abnormal conditions for rapid response.
Traditional remote PLC access relies on VPNs — hardware VPN routers at each site, VPN client software on every workstation, IT management of certificates and credentials, and firewall rules that open inbound ports to industrial networks. For a single site, that's manageable. For 10 or 50 remote sites, VPN infrastructure becomes a full IT project.
SCADA Cloud's edge connector model eliminates VPN complexity entirely. Each site has a single lightweight process that makes outbound HTTPS connections — the same protocol as your browser visiting any website. No inbound ports, no VPN appliances, no IT involvement. The plant network stays fully isolated from the internet.
For Modbus device validation before deployment, use the Modbus slave simulator to emulate the register map of your remote PLCs. Configure your SCADA tags against the simulator first, then deploy the edge connector to site with confidence. See also Modbus TCP simulator for network-based device simulation.
A lightweight edge connector installed on a plant PC reads Modbus registers locally and pushes data to SCADA Cloud over outbound HTTPS — no inbound ports needed. Your PLC network stays private. Engineers access dashboards from any browser URL without VPN configuration.
Yes. Each site installs one edge connector. All sites appear in one SCADA Cloud account. Create global overview dashboards or site-specific views. Role-based access lets local operators see only their site while central teams see all sites.
Any PLC with Modbus TCP over ethernet or Modbus RTU via RS-485/RS-232. Siemens S7-1200/1500, Schneider Modicon, Allen-Bradley Micro820/850, Delta, Mitsubishi, and hundreds of others. If it speaks Modbus, SCADA Cloud can monitor it remotely.
Yes. All traffic is TLS-encrypted. The edge connector makes only outbound connections — your PLCs are never internet-exposed. Role-based access control with full audit trail. Architecture follows enterprise SaaS security standards.
Yes. Email alerts go to any email address when alarm thresholds are exceeded. You can acknowledge alarms from your phone browser. Different recipients per site or per alarm severity. No app needed — fully browser-based.
60 days free. All features. No credit card. Your first remote site up in under 10 minutes.
