Native support for the protocols your plant already speaks.
ScadaHud includes native drivers for the protocols widely used across industrial automation. No third-party OPC servers, no per-protocol add-on licenses, and no extra hardware required.
Connect directly to PLCs, RTUs, meters, sensors, cameras, network devices, and other field equipment.
OPC UA
Industrial connectivityEncrypted, certificate-based OPC UA connectivity for modern PLCs, RTUs, gateways, and historians. Browse, subscribe, and write support powered by the OPC Foundation .NET SDK.
MQTT
IIoT & Unified NamespacePublish/subscribe messaging for IIoT brokers and Unified Namespace architectures. Sparkplug B compatible, with TLS and mTLS authentication.
Modbus TCP
Industrial connectivityModbus TCP over Ethernet for field instrumentation, energy meters, and modern PLCs. Auto-block optimization enables faster polling and more efficient data collection.
Modbus RTU
Serial connectivityModbus RTU over RS-485 and RS-232 for legacy PLCs, energy meters, and remote I/O modules.
Siemens S7
PLC connectivityDirect read and write support for Siemens S7-300, S7-400, S7-1200, and S7-1500 PLCs programmed in TIA Portal. No intermediate OPC server required.
DNP3
Energy & infrastructureDNP3 master support for electric utilities, substations, water systems, wastewater systems, and remote RTUs. Supports class polling, integrity polling, and unsolicited responses.
IEC 60870-5-104
Energy & grid systemsIEC 60870-5-104 master and slave support for utility SCADA systems. General interrogation, clock synchronization, control commands, and optional TLS support via IEC 62351-3.
BACnet/IP
Building automationBACnet/IP support for building automation systems, including chillers, AHUs, VAVs, and BMS controllers, all from one platform.
SNMP
Network & infrastructure monitoringSNMP v1/v2c/v3 polling and trap reception for switches, UPS systems, servers, and managed network equipment. Bring IT infrastructure visibility into your OT environment.
REST API
System integrationPull data from HTTP-based services using templated requests and JSON path mapping. Integrate with ERP, MES, weather services, energy market platforms, and custom device APIs.
Industrial Vision
Image-based data captureImage-based meter reading for analog and digital displays. Works with industrial cameras and existing IP cameras.
Send data, alarms, and events to the systems that need them.
External Historians
Stream tag data to existing PI System or process historian environments over REST or MQTT, with tag mapping and custom time windows.
Cloud Integrations
Publish data to AWS IoT Core, Azure IoT Hub, Google Cloud Pub/Sub, or MQTT-based cloud infrastructure using MQTT or REST payloads with certificate-based authentication.
MES & ERP
Documented REST API for production reporting, OEE, and order integration. Works with SAP, Odoo, Microsoft Dynamics, and other enterprise systems.
BI & Analytics
Query historian data directly from Power BI, Grafana, Tableau, and Metabase. Access raw data without rebuilding dashboards.
Notification Channels
Deliver alarms and rule-based automation actions through email, SMS, WhatsApp, and webhooks.
Identity & Access
Centralized sign-on and role mapping through LDAP, Active Directory, and JWT-based SSO.
