The SIMATIC S7-400H is used to avoid downtimes. As a member of the well-tried SIMATIC S7 family, it is based on standard components. The SIMATIC S7-400H provides the highest level of availability thanks to its redundant configuration, and can be as easily programmed as a standard system. All modifications can be made in online mode. In such cases, both CPUs are automatically updated. The CPUs can be expanded by adding ET 200M or S7-400 signal-modules.
Overview of further highlights:
Easier handling:
Most redundancy-relevant functions are hidden from the user
Easier parameter initialization:
The parameters for redundancy-specific functions and configurations can be comfortably assigned using the STEP 7 option package
Easier programming:
SIMATIC S7-400H is programmed in the same way as a non-redundant standard system. All standard programming languages, that can be used for the SIMATIC S7, can also be used here without restriction
Easy porting:
The program for non-redundant systems can be easily ported for redundancy and vice versa
