The AcuHMI is a human-machine interface (HMI) with an integrated multi-protocol gateway for centralized monitoring, control, and management of multiple devices across different networks. The gateway protocol supports upstream and downstream Modbus and BACnet devices via Ethernet and RS485. Dual Ethernet can be enabled for RSTP bridging and daisy chaining. Built-in 32GB memory reserved for data logs are time-stamped to UTC standardize time and date format. Webpage Interface allows remote access for advanced device configuration for alarms, data post file transfer, and event logs.

The AcuHMI human machine interface provides a main control hub that will connect the system operator to the metering devices in a facility. The 7-inch, 800x480 pixel interactive display renders detailed on-screen UI controls, visualization charts and tabular data in full colour. Centrally view real-time data across all downstream devices to oversee device status, alarm notifications, and settings on a single HMI screen.
Built-in Webpage Interface is a centralized software platform accessible from a computer browser anywhere, anytime. It allows operators to monitor aggregated metering data, while streamlining device connection management to the AcuHMI. Advanced device settings can be controlled from the interface allowing the system operator to standardize the configuration process across all devices.
Power distribution units can be paired with an HMI, gateway, or meters to form an essential part of data center infrastructure to administer power delivery to servers, computers, and other critical IT components. This allows facilities to better optimize power management and scale operations according to cost and performance goals.
The AcuHMI combines an HMI display and gateway allowing operators to monitor and control devices across different networks through a single interface. The HMI centralizes operations by allowing users to view and configure devices and energy data management directly from the HMI or remotely from the Webpage Interface.
Gateway supports multiple upstream and downstream protocols allowing device interoperability across networks, and integration to cloud services for full vertical integration.
Connect multiple devices to the AcuHMI Ethernet and RS485 ports to streamline network configuration for each unit. Rapid Spanning Tree Protocol automatically optimizes network pathways by blocking redundant links, loops and link failures.
Store aggregated real-time and historical energy parameters from each metering device for audit, analysis and performance measurements.
AcuHMI supports up to three post method channel configurations to automatically and securely post data log files to a file server for storage, reporting, and analysis
Manage device alarms for each meter connected to the AcuHMI. Alarms logs can be viewed based on device or consolidated into a single view for easy diagnostic.

The AcuHMI supports downstream protocols such as Modbus RTU, Modbus TCP/IP, BACnet MS/TP, and BACnet IP. Upstream protocols include MQTT, SNMP, Modbus TCP/IP, BACnet IP, FTP/SFTP, HTTP/HTTPS, AWS IoT, and Google IoT.
With dual Ethernet ports configured for Rapid Spanning Tree Protocol (RSTP), AcuHMI enables daisy-chain networking while preventing loops. If a link fails, traffic is automatically rerouted within milliseconds, minimizing downtime.
Yes. AcuHMI includes 32GB memory for time-stamped logging. Data can be posted to external servers for long-term storage, analysis, or audit using standard transfer protocols such as HTTP, HTTPS, FTP, and SFTP.
The AcuHMI supports configurable alarms for parameter thresholds and device online/offline status. Triggers activate a visual LED alert, while all events are logged for review. Email notifications can also be configured.
User access is managed through a role-based system. Default roles include View (read-only) and Admin (full access). Multi-user support allows concurrent logins, while password management enforces account security.
