[implementation of edge device connection in the iiot era] is widely compatible with using the standard mqt protocol to connect to the Internet of Things Platform. [edge computing] the n580 takes the initiative to perform data acquisition and internal computing, and then transmitted to the cloud platform via custom json format. Edge computing gateway can effectively relieve server pressure. [data transmission encryption] supports SSL/TLS encryption in tcp, httpclient and mqt operation mode, and supports two-way certificate authentication. [PUSR Cloud management] is easy to perform edge computing, pairing connection, remote operation and maintenance. [modbus gateway] transmission between modbus rtu protocol and modbus tcp, support for voting multiple modbus hosts. Support for up to 128 data points for data acquisition and modbus address mapping. [Basic Function] Two-way data transmission between RS485 port and ethernet. [Cascade Connection Function] The dual Ethernet port 10/100Mbps supports switching function and other devices can be concatenated via usr - n580. [Various working modes can be freely chosen] n580 supports tcp clients, tcp servers, udp clients, udp servers, httpd clients (back support of mqtt clients) and other modes; With simple configuration, you can implement the data transmission function. [ARM scheme (Cortex kernel - m7) offers a better experience] ARM Cortex scheme - m7 9, 4 CPU 80mhz, flash memory 1m Ram + 4M This scheme has the characteristics of short transmission delay, fast data transmission speed, flexible expansion and stability. (mqtt / SSL / IPv6 and other major protocols are about to be released, please see more information directly).
