PROFINET/Industrial Ethernet
Communication for SIMATIC S7-400
CP 443-1 Advanced
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
•
Security functionality, firewall and VPN
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.
In addition, the CP 443-1 Advanced provides e-mail functions
and user-created Web pages, offering ideal support for mainte-
nance and quality assurance. The Internet functions such as
FTP even allow connection to the most diverse PC-based sys-
tems. This CP is therefore the bridge between the field level and
the management level for the S7-400. The CP 443-1 Advanced
connects seamlessly to the security structures of the office and
IT worlds.

Benefits
•
Cost advantage due to connection to two separate Ethernet
segments with integrated network separation
•
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 telephone network (ISDN)
- Monitoring with IT network management tools (SNMP)
- Module replacement 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
- Secure remote access via the Internet by means of data
encryption (VPN) and data integrity checking
- Traceability by means of data logging on the basis of
standard IT mechanisms (Syslog)
•
Later connection of existing SIMATIC S7 systems to Industrial
Ethernet using the CP 443-1 Advanced ensures investment
protection
