The main window is divided into three panes:
The PMU software includes a comprehensive system administration module that allows administrators to control user access and system configuration. The System menu enables users to change their passwords, create new users, and define user permissions. To protect schemes and data, administrators can define lower-level users who do not require full system access. Permissions can be assigned on a granular basis, including read-only or no access for specific functions.
Where tariff schemes are created, edited, and stored.
To maintain data integrity and prevent unauthorized access, PMU incorporates: Elster Metering Systems Power Master Unit Software
The is a specialized Windows‑based platform engineered for programming, configuring, and extracting data from Elster’s industrial and commercial polyphase meters, including the widely deployed A1120, A1140, A1700, AS230, and PPM families. Developed during the formative years of advanced metering infrastructure (AMI), the PMU serves as a flexible on‑premise tool that bridges the gap between utility head‑end systems and the meters that measure consumption across thousands of sites.
By utilizing the precise calibration and TOU configuration tools within the software, utilities eliminate billing discrepancies. This ensures that industrial clients are billed accurately for their exact peak demands. Reduced Operational Costs
Automated data collection via the software reduces the need for manual read-outs and physical site visits. The main window is divided into three panes:
Some users expect to open an .mpl file directly, but the PMU does not work like a conventional file‑based application. Instead, the file must be copied to the Scripts directory, made read‑only, and then associated with a scheme of the same name. The PMU will then use that script during the next communication session.
Different meter models may require specific software versions: : Commonly used for : Specifically designed for Legacy Support
Supports a wide range of protocols and hardware, including PSTN/GSM modems, RS232, RS485, and (IEC 62056-21). Permissions can be assigned on a granular basis,
The software helps analyze voltage sags, swells, and harmonics, which are vital for maintaining equipment longevity across the grid. 🔐 Security and Interoperability
It reads hardware sensors that detect magnetic interference, terminal cover removal, or reverse energy flow. Supported Hardware and Use Cases
By combining the PMU with Elster’s broader software ecosystem – EnergyAxis, EnergyICT, and Connexo – utilities can build a complete metering infrastructure that spans from the meter base to the boardroom, preserving past investments while embracing the future of smart energy management.
