Featuring web-based interface for easy operations, the user could connect to PMC/PMD webpage via browsers to review the power data, set up system setting, manage power demand and perform logic rule setting for alarm notification.

In addition to display power data of the power meter in text format, the power data can also be displayed in real-time and historical trend chart for user to easily identify the variation of the electricity usage of the devices.


The PMC/PMD features a built-in Micro SD card to save the power data which PMC/PMD retrieve from power meter and regularly send back the data files to the backend management center for data analysis and statistics. In addition, PMC/PMD also offers a complete data file recovery mechanism so that when experiencing network disconnection, the data log files will be recovered after the network is resumed to ensure the system operates properly.

PMC/PMD provides historical data report inquiry and display function, the easy-to-read report of the historical power data would help to understand current electricity usage of the equipment.

Power usage effectiveness(PUE) is a measure of how efficiently a computer data center uses energy; specifically, how much energy is used by the computing equipment (in contrast to cooling and other overhead). The lower PUE value, means the higher of the greening degree of a data center. Using PMC/PMD with ICP DAS power meter to set up a power monitoring system allows user to review the PUE value through the webpage, thereby evaluate the efficiency of energy usage of the data center.

PMD (Power Meter Concentrator with Display) series is equipped with TFT LCD (with Touch Panel). It provides an easy way for viewing the power data and set up the system parameters on sites.


PMC/PMD is equipped with IF-THEN-ELSE logic engine. The user could complete the control logic via web page and download the logic rules to the PMC/PMD. The logic engine will loop execute the rules in order. By editing the IF-THEN-ELSE logic rules, the user could use "Real time power data", "Historical Statistic power data", "power demand value", "PUE value".... etc in the IF condition setting. In addition, the Schedule setting and channel values of I/O modules connected to the PMC/PMD can be also included in the IF condition. When the evaluation of the IF condition is matched, the corresponding action will be executed (such as: alarm message sending or adjust the operation of equipment). By this way, the user could quickly implement applications for power usage monitoring, power demand management, and alarm notification sending.

PMC/PMD can connect to ICP DAS M-7000 I/O modules or Modbus TCP/RTU slave modules according to the needs of the applications. With flexible and diversified I/O modules support and IF-THENELSE logic rule, it enables to control the operations of devices in real time, and provides maximum flexibility for system operation and power saving.
PMC/PMD provides Schedule function that allows to edit logic for applications that requires Schedule operation. The Calendar interface allows to easily set up the schedule for weekdays or weekends so that the user could schedule the operations for the equipments as required for efficient power usage.

PMC/PMD can integrate Instant Messaging services such as LINE, Telegram, and WeChat to achieve alarm message notification function. The message sending action can be added to the IF-THEN-ELSE logic edition as part of logic control to provide real-time message notification to the related personnel when an event occurs. The alarm message content could be a preset string with power data or I/O channel data. In addition, the PMC/PMD can also send the alarm notification via SMS or Email.

In addition to Ethernet communication, PMC-523xM-3GWA/4GE/4GC & PMC-2x4xM(X)-4GE/4GC also supports 4G/3G mobile network communication. It can send the real-time power data, data logger files and alarm messages back to the control center by 4G/3G mobile network.

PMC/PMD supports the MQTT protocol. It can publish the power data of the power meters (connected to PMC/PMD) to the MQTT broker. In addition, PMC/PMD can also receive the message of the subscribe MQTT Topics published by others MQTT device and use them in the IF-THEN-ELSE logic rule to trigger the corresponding action.

PMC/PMD provides powerful and flexible integration with the power meters at the field side, and also supports various IoT protocols for seamless integration with the SCADA/MES/MIS/IT/IoT systems to transfer the power data from the front-end to the back-end management systems. It also features reliable thought-out power demand management and data logger functions. All of these features make PMC/PMD a perfect concentrator of power meters in the Energy Management application of the IoT age.

In the era of IoT and Cloud computing, power data transmission between the power meter and Cloud platform is a prerequisite for maintaining an effective operation of the IoT Cloud system. To ensure the operations of power data uploading from PMC/PMD to Cloud platform to meet the requirements of Security mechanism, PMC/PMD supports Security mechanism such as "MQTT with SSL/TLS" to perform the encryption of real-time Sensor data during the data transmission operation. In addition, PMC-284xM also supports the Security mechanism such as VPN Client (Virtual Private Network), SNMP agent v3 (Enhanced security for SNMP protocol), SFTP(Secure File Transfer Protocol), FTPS(FTP over SSL) and HTTPS. With a variety of Security mechanism and protocols provided by PMC/PMD, it can meet the requirements of information Security when building an IoT Cloud power monitoring system.

PMC/PMD supports the connection ability with the IoT Cloud Platform as Microsoft Azure, IBM Bluemix and Amazon Web Service etc. It works as the concentrator in the IoT application to connect with power meters, collect and transfer the power data to the cloud platform for future data analysis. PMC/PMD also can receive the message which is published from the cloud platform for the corresponding actions at the field side. In addition, PMC/PMD also supports connections to ICP DAS IoTstar cloud management software. IoTstar enables the Controller Remote Access Service, Power Data Collection Service, Power Data Visualization Service, Power Data Report Service and Bot Service with Mobile Phone on PMC/PMD.
