PROFINET/Industrial Ethernet
Communication for SIMATIC S7-400
CP 443-1
2
■
Overview
Communications processor for connecting a SIMATIC S7-400
to Industrial Ethernet networks, also as PROFINET IO controller
or in SIMATIC H systems.
The CP supports:
•
PG/OP communication
•
S7 communication
•
Open communication (SEND/RECEIVE)
•
PROFINET communication
•
IT communication
The communications processor can also be used for redundant
S7 communication in SIMATIC H systems and for fail-safe
applications (PROFIsafe) in connection with an S7-400 F-CPU.
■
Benefits
•
High plant availability through the support of media
redundancy (MRP) and use in the SIMATIC S7-400 H system
•
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 exchange without programming device using the
C-PLUG swap medium
•
Securing the system against unauthorized access
by means of
- Central access protection for any devices within an
automation cell, e.g. by means of authentication of the
network stations
•
The capability of later connecting existing SIMATIC S7
systems to Industrial Ethernet using the CP 443-1 ensures
investment protection
■
Application
•
The CP 443-1 is used to connect the SIMATIC S7-400 to
Industrial Ethernet networks. With its own processor, it relieves
the CPU of communications tasks and facilitates additional
connections.
The CP 443-1 offers communication options with
• PGs/PCs
•
Host computers
•
HMI systems
•
SIMATIC S5/S7/C7 systems
•
PROFINET IO devices
■
Design
The CP
443-1 features all the advantages of the SIMATIC S7-400
design:
•
Compact design:
- Two RJ45 sockets for connecting to Industrial Ethernet;
automatic data rate detection by means of the autosensing/
autocrossover function; the connection is made via the
IE FC RJ45 Plug 180 with 180° cable outlet or via a standard
patch cable
- Diagnostics LEDs for indicating the operational and
communication status
•
Easy installation:
The CP 443-1 is mounted on the S7-400 rack and connected
to the other modules via the backplane bus. No slot rules
apply.
•
The CP 443-1 can be operated without a fan
•
The CP 443-1 can also be operated in the expansion rack (ER)
in conjunction with the IM 460/461
•
The module can be replaced without the need for a
programming device
■
Function
•
Two RJ45 ports with 10/100 Mbit/s full/half duplex with
autosensing and autocrossover functionality via integral
2-port switch
•
Communications services of the interface:
-
Open communication (TCP/IP and UDP): 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
- S7-H-communication for S7-400-H-systems, now also
across network boundaries (ISO-on-TCP)
- Certified PROFINET IO controller with real-time properties
(RT and IRT)
- IP address assignment via DHCP, simple PC tool or via
program block (e.g. for HMI)
•
Media redundancy (MRP):
- Within an Ethernet network with ring topology, the CP
supports the media redundancy procedure MRPMRP as an
MRP Manager and as an MRP Client
•
Diagnostics and network management:
- Comprehensive diagnostics functions for all modules in the
rack (including graphical diagnostics, e.g. topology)
- Integration in network management systems due to support
of SNMP V1/V3
