CP 443-1 / SIPLUS CP 443-1
The CP 443-1 and the SIPLUS CP 443-1 are designed to connect a SIMATIC S7-400
system to Industrial Ethernet networks.
The communications processors support:
● PG/OP communication
● S7 communication
● Open communication (SEND/ RECEIVE)
● PROFINET communication
● IT communication
The communications processors are also suitable for redundant S7 communication in
SIMATIC H systems and for applications for the functional safety of the communications
technology, for example PROFIsafe in conjunction with an S7-400 F-CPU.
The additional characteristics and functions are as follows:
● A PROFINET interface with two RJ-45 connectors. Connection is via an IE FC RJ-45 plug
180 with 180° cable outlet or via a standard patch cable.
● Diagnostics LEDs for displaying the operational and communication status.
● 10 /100 Mbps, full / half duplex with the functionality for autosensing and autocrossover
via an integrated 2-port switch.
● In conjunction with the interface module IM 460/461, the CP 443-1 can also be operated
in an expansion rack (ER).
● Fanless operation of the communications processor.
● The communication services operate via the following interfaces:
– Open communication (TCP/IP and UDP), multicast for the UDP incl. routing between
– Inter-network PG/OP communication with S7 routing
– S7 communication (client, server, multiplexing) incl. routing between the two interfaces
– S7-H communication for SIMATIC S7-400 H systems
– PROFINET IO controller with real-time properties due to RT and IRT
– The IP address is assigned using DHCP, a simple PC tool or a program block, such
● Media redundancy (MRP):
– In an Ethernet network with ring topology, the communication processor supports the
● Diagnostics and network management:
– Extensive diagnostics functions of all modules of the rack
– Integration in network management systems by supporting SNMP V1/V3
● A wide range of diagnostics options with LEDs, in STEP 7 and Web-based diagnostics
units incl. monitoring by IT network management tools (SNMP V1 MIB II)
