Communications processors for SIMATIC S7
8.2 Communications processors for SIMATIC S7-300
● Communications services:
– Open communication with TCP/IP, UDP, multicast for UDP and ISO
– Inter-network PG/OP communication with S7 routing
– S7 communication (client, server, multiplexing)
● Media redundancy (MRP):
– In an Ethernet network with ring topology, the CP 343-1 supports the media
● Diagnostics and network management:
– Extensive diagnostic functions of all modules within the racks
– Integration in network management systems by support of SNMP V1
● Security mechanisms:
Access protection with a configurable IP-ACL (IP Access Control List)
● Configuration of all functions with STEP 7 as of V5.4 or STEP 7 Professional V11
● Module replacement without programming device by storing the configuration data on the
CPU
● SIPLUS CP 343-1
The SIPLUS CP 343-1 module is designed for environmental loads at ambient
temperatures of 0 °C to +60 °C. One variant of the SIPLUS CP 343-1 is designed for
harsh environmental conditions at ambient temperatures from -25 °C to +70 °C.
CP 343-1 Advanced / SIPLUS CP 343-1 Advanced
The CP 343-1 Advanced and the SIPLUS CP 343-1 Advanced have the same range of
functions as the CP 343-1 / SIPLUS CP 343-1. They also have the following additional
characteristics and functions:
● Two separate interfaces (integrated network separation)
– Gigabit interface
– PROFINET interfaces:
● 30 MB of flash memory with a file system for user-defined HTML pages and 30 MB of
RAM for buffering dynamic data
● File exchange with other computers using FTP
● An integrated HTTP server that allows write and read access to process and status data
of the S7-300 system. System diagnostics is therefore possible via secure Web browser.
● An integrated ESMTP client for secure, event-dependent sending of e-mails that can also
contain variables. The current value of such a variable is queried when the program of
the S7-300 CPU triggers the sending of the corresponding e-mail
● A C-PLUG for storing the configuration data ships with the product
