LoRa and short range RF module slave devices are available for connecting the sensors and meters. In addition, the ZM6380 can connect to different sensors and meters through RS485, LoRa and Short Range RF for IoT system implementation. Should there be a surge in loading demand, the system will identify the source of issue and tailor a solution to pre-empt the facility from being charged the maximum tariff rate. The overall risk and maintenance costs are thus kept in check. Data collected through the Modbus converter are analysed for energy efficiency measures. When in Modbus mode, the ZM6380 will serve as a bridge between BMS’ Modbus protocol and the IEC meter standard used in the electricity sector, enabling active remote monitoring of energy usage in various locations within a commercial/industrial facility. This DCU can double as a Modbus converter for energy conservation purpose in Building Management System (BMS). Upon request, the packed and compressed data files will be efficiently transmitted to a central server.
When set in DCU mode, the device will periodically poll readings from a cluster of meters, compress and encrypt the data before saving them to local storage and simultaneously as backup to an SD card. A variety of protocol sets are also available to support different meter standards adopted by various manufacturers. This DCU incorporates an MCU running on Linux platform to provide multiple communication interface options such as LAN, LTE 4G, NBIoT, WCDMA 3G, HSPDA, GPRS, LoRa, Short Range RF, RS232 and RS485 serial connectivity in order to ensure two-way meter data communication in a reliable, efficient, and cost-saving manner.
Master Unit V (AS230) Installer.The ZM6380 is a microprocessor-based Data Concentrator Unit (DCU) designed especially for remote data reading of clusters of electric meters. The software to program the Elster AS230 is called PMU 3.0 and can be downloaded from us at: The software to program the Elster A220 and AS1440 is called Alphaset, and is also available from Elster. The version that we currently use to program Elster A1140s and A1700s is PMU 2.4 and can also be downloaded from us at:
It is always best to check with Elster first, since they bring out newer versions of the software from time to time. If you go and visit them in Industria in Johannesburg, they have a stack of CDs that they give away for free. The Elster Meter Programming Software (called PMU - Power Master Unit) is available from Elster for free.
