How can I access remote data from measurement units?

Remote data retrieval protocols:

• Modbus RTU (RS485) : Industrial standard. Twisted-pair shielded cable up to 1200m. 9600–38400 baud. Real-time parameter polling. Compatible with most SCADA/PLC systems.
• Modbus TCP/IP (Ethernet) : TCP/IP protocol over standard Ethernet (RJ45). Low latency, simultaneous multi-client access. Ideal modern data centers and cloud integration.
• Profibus DP : Fieldbus protocol for deterministic real-time data. Used in advanced industrial automation (Siemens PLC, ABB systems).
• Wi-Fi / cellular gateway : Optional modules (Socomec ION-series) provide wireless connectivity. Data pushed to cloud dashboard or MQTT broker. Geolocation flexibility; no cable runs.
• BACnet (ASHRAE Standard 135) : Building automation protocol. Meters with BACnet IP interface integrate with facility management systems (Tridium, Honeywell, Johnson Controls).
• M-Bus (Meter Bus) : Low-power master-slave protocol for residential/commercial metering. Automatic hourly/daily data collection.
• Pulse output : Isolated dry contact relay. One pulse = 1 kWh (or configurable). Legacy systems, non-networked setups.

Socomec meters support multi-protocol simultaneous communication (Modbus + Profibus + pulse concurrently). Data logging on device (SD card up to 1 year). Integration with ISO 50001 energy management systems. Optim-elec.com ensures proper protocol selection and BMS commissioning.
