PROFINET/Industrial Ethernet
Communication for SIMATIC S7-300
CP 343-1 Lean
2
■
Overview
Communications processor for connecting a SIMATIC S7-300
to Industrial Ethernet networks, also as PROFINET IO Device.
The CP supports:
•
PG/OP communication
•
S7 communication
•
Open communication (SEND/RECEIVE)
•
PROFINET communication
■
Benefits
•
High level of plant availability due to support of media
redundancy (MRP)
•
Optimum support of maintenance through
- Web-based diagnostics
- Remote programming via WAN or a telephone network
(ISDN)
- Monitoring by means of IT network management tools
(SNMP)
- Module replacement without programming device thanks to
saving of the configuration data on the CPU
•
The capability of later connecting existing SIMATIC S7
systems to Industrial Ethernet using the CP 343-1 Lean
ensures investment protection
■
Application
The CP 343-1 Lean is used to connect the SIMATIC S7-300 to
Industrial Ethernet networks. With its own processor, it relieves
the CPU of communications tasks and facilitates additional
connections.
The CP 343-1 Lean offers the communication options of the
S7-300 with
• PGs/PCs
•
Master computers
•
HMI devices
•
Other SIMATIC S5/S7 systems
•
PROFINET I/O Controllers
■
Design
The CP 343-1 Lean offers all the advantages of SIMATIC S7-300
system design:
•
Compact design;
the rugged plastic casing features on the front:
- Two RJ45 sockets for connecting to Industrial Ethernet with
automatic detection of transmission rate by means of
autosensing;
RJ45 sockets have an industry-compatible design
with additional retaining collars for connection of
IE FC RJ45 Plug 145/180
- Diagnostic LEDs for each switch port
- 2-pin plug-in terminal strip for connection of the 24 V DC
external supply voltage
•
Easy installation;
The CP 343-1 Lean is snap-mounted on the S7-300 DIN rail
and connected to adjacent modules through the bus
connectors. There are no slot rules.
•
The CP 343-1 Lean can be operated without a fan. A standby
battery is not required.
•
In combination with IM 360/361, CP 343-1 Lean can also be
used in an expansion rack (ER).
■
Function
•
PROFINET interface with two RJ45 ports, 10/100 Mbit/s
full/half duplex with autosensing and autocrossover function-
ality via 2-port switch
•
Communication services via interface:
- Open communication (TCP/IP, UDP): Multicast for UDP
- PG/OP communication: inter-network with S7 routing
- S7 communication (server only)
- PROFINET IO device
•
Media redundancy (MRP):
- Within an Ethernet network with ring topology, the
CP supports the media redundancy procedure MRP
•
Diagnostics and network management:
- Extensive diagnostic functions for all modules in the rack
- Integration into network management systems through the
support of SNMP V1
•
Configuring of all functions with STEP 7, V5.4 or higher, or
STEP 7 Professional V11 (TIA Portal) or higher
•
Module replacement without programming device thanks to
saving of the configuration data on the CPU
