In recent years, under the goal of sustainable development of ESG for the earth, governments, organizations and enterprises around the world are facing the pressure of "Low-carbon and energy-saving" to avoid excessive waste of earth resources and protect the sustainable development of the earth. Under the wave of ESG sustainable development, the "Low carbon and Energy saving" effect that can be achieved through power monitoring is the most significant. Therefore, ICP DAS provides the Advanced IIoT power meter concentrator-PMC-2841M to help customers quickly build power monitoring systems that meet the requirement of "Low carbon and energy saving".

PMC-2841M uses more powerful hardware platform. It not only inherits the characteristics from the original PMC series products (Such as monitor the power usage information of equipment/machine by browser, comprehensive IF-THEN-ELSE power demand management capabilities, connect with a variety of power meter for different requirements, provide instant message notification functions, etc.), but also features more powerful IoT security protection mechanism to enhance the overall security of the power monitoring system and strengthen the network connection with the IoT cloud system. Following is the security protection mechanism PMC-2841M can provide.

● Network Security: PMC-2841M features the VPN communication function (supports 4 VPN protocols : PPTP, L2TP, OpenVPN and SoftEther), which allows users to set up a secure communication tunnel between PMC and the internet, and the security of the network through VPN can also prevent the PMC and its connected power meters from being invaded by external threats.

● System Security: PMC-2841M supports the HTTPS encrypted communication protocol, which can encrypt the communication content between the browser and PMC to protect the settings and operations performed on PMC from being interpreted. SNMP v3 encryption communication protocol and the authentication mechanism of user management are also provided to ensure the security of connections between PMC and IT system to ensure the security.

● Data Security: PMC-2841M is equipped with a microSD card, which can be used to perform the data log operations for the power meters connected to PMC. The data log files can be automatically sent back to back-office through the FTPS protocol, or actively downloaded by user through SFTP, FTPS or web protocols. The transmission of data log files is protected by TLS encryption to ensure the data log files not being captured or tampered during the transmission process.

● Identity Authentication Security: PMC-2841M supports the function of Blacklist/Whitelist, which allows users to filter and exclude the accessible domains. It can also perform the dynamic blacklist function to automatically add the IP address with too many wrong login attempts to PMC to blacklist to protect PMC from the brute force password attacks.
