Data Acquisition Server

Data Acquisition Server
AcuLink 810

Accuenergy’s AcuLink 810 is a data acquisition server and gateway designed to collect aggregated energy data from up to 32 Modbus meters and field sensors in a facility such as water, gas and electricity. This information is locally stored until it is ready to be distributed to remote servers or controllers via an IP-based network

AcuLink 810 provides an easy solution to manage, collect and sto

  • Mbus Meters Integration Now Supported. Including:
    • Modbus-RTU (standard + SunSpec)
    • Modbus-TCP/IP
    • BACnet-MS/TP
    • BACnet-IP
  • Auto-Discover BACnet-IP and BACnet-MS/TP – automatically finds available BACnet devices on the network.
  • NMP Gateway – Convert connected Modbus, BACnet and Mbus devices to available SNMP devices, designed for data center management systems
  • Added MQTT protocol, a new data integration protocol for IoT applications
  • Support reading SunSpec devices. Simplified integration with any SunSpec supported meters and inverters
  • Data Acquisition via BACnet-IP. Now supports four acquisition protocols: Modbus-RTU (standard + SunSpec), Modbus-TCP/IP, BACnet-MS/TP and BACnet-IP
  • Rapid logger. Log data in 1-second interval (previously support 1-minute interval)
  • Support building BACnet device template by converting EPICS file
  • Pulse counter data can be polled via Modbus-TCP and BACnet-IP directly
  • BACnet-MSTP data acquisition
  • AcuMesh support on AcuLink 810 (Wirelessly query meters with RS485)
  • BACnet gateway (Convert Modbus-RTU and BACnet-MSTP to BACnet-IP)
  • Remote device access
  • Maintain high availability by RSTP protocol (two ports connect to same subnet)
  • Ethernet gateway for Modbus RS485 and digital output devices
  • Access energy information remotely via web server, or push to IP-based master devices or software
  • Data acquisition and logging with 8GB on-board memory
  • Embedded web-server for real-time data and easy configurations
  • Controller/Master system can poll data from all RTU devices via Modbus-TCP/IP Protocol
  • Dual ethernet RJ45 port and WiFi communication channels
  • Enhanced cybersecurity for critical infrastructure deployment
  • Compact DIN rail mount design
  • Track energy usage and peak demand
  • Quick and simple software-free setup
