8.4 Communications processors for SIMATIC S7-400
Industrial Ethernet
322 System Manual, 09/2019, C79000-G8976-C242-10
● Security mechanisms:
– Access protection with a configurable IP-ACL (IP Access Control List)
● Configuration of all functions with STEP 7 as of V5.4
● Configuration with STEP 7 Professional V11 or higher.
● Module replacement without PG by storing all data on the CPU.
● SIPLUS CP 443-1
● The SIPLUS CP 443-1 module is intended for environmental loads at ambient
temperatures of 0°C to +60°C.
CP 443-1 Advanced / SIPLUS CP 443-1 Advanced
The CP 443-1 Advanced and the SIPLUS CP 443-1 Advanced are designed for connection
of a SIMATIC S7-400 system to Industrial Ethernet networks also as a PROFINET IO
controller or in SIMATIC H systems.
The additional characteristics and functions are as follows:
● PROFINET communication
– In addition to PROFINET IO communication, PROFINET CBA (Component-Based
Automation) is also available here.
– This makes communication between technological modules (distributed intelligence)
possible.
– Users can choose between cyclic and acyclic communication.
This form of communication is suitable both for non time-critical as well as time-critical
applications.
● Configurable keepalive function
● Two separate interfaces (integrated network separation):
– Gigabit interface with an RJ45 connection for 10/100/1000 Mbps full / half duplex with
the autosensing functionality.
– PROFINET interface with four RJ45 connectors for 10/100 Mbps full / half duplex incl.
autosensing and autocrossover functionality via an integrated 4-port switch.
● 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
● Integrated HTTP server that allows write and read access to process and status data of
the S7-400 system. This means, for example, that system diagnostics is possible via a
secure Web browser.
● Integrated ESMTP client for reliable event-driven sending of e-mails that can also include
variables. The current value of such a variable is queried when the program of the S7-
400 CPU triggers the sending of the corresponding e-mail.
● A C-PLUG for storing the configuration data ships with the product.
