Product Overview
The Siemens 6AG1414-5HM06-7AB0 is a SIPLUS S7-400 CPU 414-5H central processing unit for high-availability SIMATIC S7-400 automation systems. It combines the processing capability of the S7-400 platform with the redundancy functions required for applications where continued controller operation is a major system requirement.
The CPU 414-5H can be used as one of the two CPUs in an S7-400H redundant controller configuration. The paired CPUs exchange synchronization information and maintain coordinated controller operation so that a fault affecting one controller does not necessarily interrupt the controlled process.
The module also supports PROFINET and PROFIBUS DP communication, allowing the CPU to interface with distributed I/O, field devices, HMI systems, engineering stations, and other automation equipment. This makes it suitable for control architectures combining rack-based S7-400 modules with distributed network components.
As a SIPLUS version, the CPU is intended for industrial environments where extended environmental capability is required. It can be considered for process plants, utilities, production systems, and infrastructure installations that use S7-400H architecture and require additional environmental robustness.

Working Principle
Process Inputs → CPU 414-5H → User Program Execution → Redundant Controller Synchronization → Output Commands
The 6AG1414-5HM06-7AB0 executes the configured S7-400 control program and processes information received from local and distributed I/O. Input data is evaluated according to the user program, after which the CPU generates output commands and exchanges process information with connected automation devices.
In an S7-400H architecture, two CPUs operate together as a redundant controller pair. Synchronization connections allow the CPUs to maintain coordinated operating states. One CPU normally handles the active control task while the redundant CPU maintains the required synchronized state and can assume control when a fault occurs.
The communication architecture supports:
- PROFINET communication with Ethernet-based automation devices.
- PROFIBUS DP communication with distributed field devices and I/O.
- Synchronization between redundant CPUs.
- Exchange of process and diagnostic information with connected system components.
- Centralized execution of the automation program for the S7-400 station.
The result is a controller architecture that combines conventional S7-400 control functions with redundancy and distributed communication.
