Communications processors for SIMATIC S78.4 Communications processors for SIMATIC S7-400Industrial EthernetSystem Manual, 09/2019, C79000-G8976-C242-10 321CP 443-1 / SIPLUS CP 443-1The CP 443-1 and the SIPLUS CP 443-1 are designed to connect a SIMATIC S7-400system to Industrial Ethernet networks.The communications processors support:● PG/OP communication● S7 communication● Open communication (SEND/ RECEIVE)● PROFINET communication● IT communicationThe communications processors are also suitable for redundant S7 communication inSIMATIC H systems and for applications for the functional safety of the communicationstechnology, 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 plug180 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 autocrossovervia an integrated 2-port switch.● In conjunction with the interface module IM 460/461, the CP 443-1 can also be operatedin 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 betweenthe two interfaces– 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, suchas for HMI● Media redundancy (MRP):– In an Ethernet network with ring topology, the communication processor supports themedia redundancy protocol MRP● 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 diagnosticsunits incl. monitoring by IT network management tools (SNMP V1 MIB II)
