PROFINET/Industrial Ethernet
Communication for SIMATIC S7-300
CP 343-1 Advanced
2
■
Function
•
Two separate interfaces (integrated network separation):
- Gigabit interface with an RJ45 connector with
10/100/1 000 Mbps full/half duplex with autosensing
functionality
- PROFINET interface with two RJ45 connectors with
10/100 Mbps full/half duplex with autosensing and
autocrossover functionality via integrated 2-port switch
•
Communications services via both interfaces:
- Open communication (TCP/IP, UDP, ISO):
Multicast with UDP, including routing between both inter-
faces
- 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 Advanced
1)
.
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)
- Secure transfer of the time of day (NTP V3)
•
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 prede-
cessor CP 343-1 (6GK7 343-1GX30-0XE0), without security
functions and CBA.
Version with security functions
1)
for TIA Portal in planning.
•
Module replacement without programming device:
all information is stored on the C-PLUG (also file system for
IT functions)
