Two separate interfaces (integrated network separation):
Gigabit interface with an RJ45 connector with 10/100/1000 Mbps full/half duplex with autosensing functionality
PROFINET interface with two RJ45 connectors with 10/100 Mbit/s full/half duplex with autosensing and autocrossover functionality via integrated 2-port switch
Communication services via both interfaces:
Open communication (TCP/IP, UDP, ISO): Multicast with UDP, including routing between both interfaces
PG/OP communication: Inter-network with S7 routing
S7 communication (client, server, multiplexing) including routing between both interfaces
IT communication: HTTP communication permits access to process data via user's own Web pages. HTTPS communication is also possible with the CP 343-1 Advanced1). The e-mail client function allows e-mails to be sent directly from the user program. FTP communication allows program-controlled FTP client communication. Access to data blocks via FTP server.
Communication services via PROFINET interfaces:
PROFINET IO controller and IO device with real-time properties (RT and IRT)
PROFINET CBA
IP address assignment via DHCP, simple PC tool or via user program
Media redundancy (MRP):
Within an Ethernet network with a ring topology, the CP supports the MRP media redundancy protocol as an MRP manager and as an MRP client
Diagnostics and network management:
Extensive diagnostics functions for all modules in the rack
Integration in network management systems due to support of SNMP V1/V3
Security mechanisms:
Access protection by means of configurable IP access list
Firewall for filtering connections on the basis of their IP/port addresses
Bandwidth limitation to avoid communication overload
VPN server and VPN client for tap-proof access to controllers
Encrypted HTML pages using SSL (HTTPs)
Secure file transfer (FTPs)
Tap-proof transfer of network analysis information to the network management system (SNMP)
Translation of private and public IP addresses (NAT/NAPT)
Configuration of all functions using STEP 7; the security functions are configured using the Security Configuration Tool (SCT) which is included in the scope of supply of STEP 7 V5.5 SP3.
Configuration with STEP 7 Professional V11; only possible with a limited range of functions of the predecessor CP 343-1 (6GK7 343-1GX30-0XE0), without security functions and CBA. Version with security functions1) Available soon for TIA Portal.
Module replacement without programming device: all information is stored on the C-PLUG (as well as file system for IT functions)
