Communication Management Unit

Introduction to SE5216 Communication Management Unit.

Interface Configuration

• Rich Serial Ports: Provides 16 RS-232/422/485 connection ports to meet the access requirements of various serial devices, facilitating connections to equipment such as relay protection devices, smart meters, measurement and control units, enabling the collection and transmission of serial data.
• Practical Network Ports: Equipped with 2 Ethernet network connection ports with a speed of 10/100Mbps, used for communication with upper-level master station systems, monitoring centers, or other network devices, ensuring efficient data transmission over the network.
• Other Functional Interfaces: Features a real-time clock to provide an accurate time reference, offering a time basis for data recording and event sequence recording; also includes a watchdog function to enhance operational stability and prevent program runaway or crashes.

Functional Features

• Protocol Conversion: Converts information received from RS-232/422/485 connection ports into ***/UDP format, enabling data exchange between devices with different communication protocols and facilitating effective data transmission between Ethernet networks and serial devices.
• Data Transmission: In automated industrial or system-integrated manufacturing, it converts data from serial devices and transmits it via Ethernet, enabling remote control and overcoming the distance limitations of serial transmission.

Application Scenarios

In power systems, it is commonly used in substation automation systems, distribution network automation systems, etc., connecting various power devices to collect and upload device data to dispatch centers. In the industrial automation field, it can connect to devices such as PLCs and sensors to achieve data exchange and collaborative work. In smart buildings, transportation, and other sectors, it also plays a role in connecting and managing multiple devices, enabling intelligent management and control of various systems.
