Interfaces, Networks And Data Communication For The S7-400 - Siemens SIMATIC S7-400 Configuration And Use Manual

Interfaces, Networks and Data
Communication for the S7-400
In this Chapter
The following information is contained in this chapter:
• The connection of multiple automation systems via the MPI interface of the
CPU. An example is provided to show how easy it is to realize data
communication among three central controller modules.
• The I/O connection via PROFIBUS DP to couple S7-400 with the distributed I/O
and devices from the SIMATIC S5 automation series.
• The I/O connection via PROFINET IO to interface distributed I/O directly to
Industrial Ethernet.
• The point-to-point communication via the communication modules CP 440,
CP 441-1 and CP 441-2
• Data exchange via communication functions
