SIMATIC S7-400

SIMATIC S7-400:

The Power Controller for system solutions in the
manufacturing and process industries

Within the Controller family, the SIMATIC S7-400 is designed
for system solutions in the manufacturing and process
automation.
• The S7-400 is especially suited for data-intensive tasks in
the process industry; high processing speeds and deterministic
response times guarantee short machine cycle times
on high-speed machines in the manufacturing industry.
The fast backplane bus of the S7-400 ensures efficient data
transfer to central I/O modules.
• The S7-400 is used preferably to coordinate overall plants
and to control lower-level communication lines with slave
stations; this is guaranteed by the high communicationpower
and the integral interfaces.
• The power of the S7-400 is scalable thanks to a graded
range of CPUs; the capacity for I/O is almost unlimited.
• The performance reserves of the CPUs make it possible to
integrate new functions without any other hardware
investment, for example, processing of quality data, userfriendly
diagnostics, integration into higher-level MES
solutions or high-speed communication via bus systems.
