支持白名单机制，仅允许预授权设备（MAC/IP）访问模块，防止未授权接入。
数据加密：
支持TLS 1.2/1.3加密通信，确保OPC UA、Modbus TCP等协议的数据传输安全。
1.Product Overview
The ABB CM577-ETH is one of the flagship models of the ABB CM series communication modules,and its core function is to provide high-speed,redundant,and secure industrial Ethernet connections to the AC800M PLC.This module supports a variety of industrial protocols(such as Modbus TCP,DNP3,IEC 61850,OPC UA),and integrates deep packet inspection(DPI)firewall,TLS encryption,redundant network and other functions,which can realize cross-system data interaction,remote monitoring,and device collaborative control,while meeting the needs of Industry 4.0 and intelligent manufacturing for real-time,security and flexibility.
2.Core functions and characteristics
1.Multi-protocol Industrial Ethernet Support
Protocol Compatibility:
Modbus TCP:supports master/slave mode,compatible with function codes 01-06(read/write coil/register),15-16(write multi-coil/register),and can seamlessly connect legacy devices(such as instruments,frequency converters).
DNP3:supports Level 2/3 functions,including time synchronization,event recording,file transfer,and is suitable for distributed monitoring scenarios such as electricity and water affairs.
IEC 61850:Supports MMS(manufacturing message specification),GOOSE(generic object-oriented substation event),SV(sampling value),and is suitable for intelligent substation automation systems.
OPC UA:supports Server/Client mode,providing data modeling,alarms and events,and historical data access functions,making it easy to integrate with IT systems(such as ERP,BI).
Profinet IO(optional):supports IO controller/device mode,suitable for Profinet ecological equipment such as Siemens.
Protocol Conversion:Built-in protocol conversion engine,which can realize cross-protocol communication such as Modbus TCP↔DNP3,IEC 61850↔OPC UA,etc.,without the need for additional gateway equipment.
2.High availability network design
Redundant Ethernet interface:
Equipped with 2×10/100/1000Mbps Ethernet ports,it supports Parallel Redundancy Protocol(PRP)and High Speed Redundancy Protocol(HSR),achieving network redundancy with zero switching time(<10μs).
Supports link aggregation(LACP),which can bind multiple physical ports into logical links,improving bandwidth(up to 2Gbps)and reliability.
Network self-healing:When the main link fails,it automatically switches to the backup link and triggers an SNMP Trap alarm to notify the operation and maintenance personnel.
Industrial hardware:
Wide temperature design:Operating temperature range-40℃to+70℃(standard model),adapting to extreme environments.
High protection level:IP65 protection(optional),dust-proof and water-proof,suitable for outdoor or harsh working conditions.
3.Industrial-grade network security protection
Deep Packet Inspection(DPI)firewall:
Filter illegal traffic based on five-tuple(source/destination IP,port,protocol)and application layer signature to prevent DDoS attacks,port scanning,and malicious protocol requests.
Supports the whitelisting mechanism,allowing only pre-authorized devices(MAC/IP)to access the module to prevent unauthorized access.
Data encryption:
Supports TLS 1.2/1.3 encrypted communication to ensure the security of data transmission of OPC UA,Modbus TCP and other protocols.
