Siemens CPU412H CPU Unit

Manufacturer: Siemens

LEDs indicate, for example, internal and external faults and operating statuses such as RUN, STOP, startup, "Master" operating mode, redundancy errors, and test function.
The programming device can be used to display signal states in the program execution sequence, modify process variables independently of the user program, output contents of stack memories, run through program steps individually, and disable program sections.
The user can obtain information about the memory capacity and operating mode of the CPU, and the current utilization of the RAM and load memory.

Features Applications Model

CPU for SIMATIC S7-400H and S7-400F/FH
Can be used in S7-400H high-availability systems
Can be used with F runtime license as F-capable CPU in S7-400F/FH safety-related systems
With integrated PROFIBUS DP master and combined MPI/PROFIBUS DP master interface
With integrated PROFINET interface (2-port switch)
Features 2 slots for sync modules

The CPU 412-5H can be used for the SIMATIC S7-400H and S7-400F/FH. It enables the establishment of an S7-400H high-availability system. It can also be used for the S7-400F/FH fail-safe automation system in conjunction with the F runtime license.
The integrated PROFIBUS DP interfaces enable direct connection as master to the PROFIBUS DP fieldbus.
The integrated PROFINET interface with switch functionality forms the basis for providing 2 externally accessible PROFINET ports. In this way, linear or ring structures can be implemented.
