Protocol Data Sources

Industrial protocol data sources enable Mango to communicate directly with field devices, controllers, and automation systems using standardized communication protocols. These are the most commonly used data source types in industrial and building automation deployments.

Available Protocol Data Sources​

  • Modbus -- The most widely used industrial protocol. Supports Modbus TCP/IP (with TCP, UDP, and Encapsulated transports) and Modbus Serial (RTU and ASCII over RS232/RS485). Ideal for PLCs, VFDs, power meters, and a vast range of industrial equipment.

  • BACnet -- The standard protocol for building automation and control. Supports both BACnet I/P (over Ethernet/IP networks) and BACnet MS/TP (over RS485 serial). Features automatic COV (Change Of Value) subscriptions for efficient data collection from HVAC controllers, lighting systems, and fire alarm panels.

  • SNMP -- Simple Network Management Protocol for monitoring network infrastructure. Supports SNMPv1, v2c, and v3 with both polling and trap reception. Used for switches, routers, UPS systems, printers, and any SNMP-enabled device.

  • OPC UA -- The modern, platform-independent OPC standard. Connects to OPC UA servers using the Eclipse Milo client library. Supports subscriptions for efficient data collection, certificate-based security, and cross-platform operation. The recommended choice for new OPC integrations.

  • MQTT -- Lightweight publish/subscribe messaging protocol for IoT and telemetry. Connects to MQTT brokers as a subscriber with support for plain text, JSON, and timestamped JSON payloads. Event-driven (no polling required).

  • OPC DA -- Legacy OPC Data Access (Classic OPC) for connecting to Windows-based OPC servers via DCOM. Required for older systems that have not been upgraded to OPC UA. Windows-only due to DCOM dependency.
