Its description — FM456-4 Applikationsbaugr. /DOS — indicates a German-market variant with application-specific firmware or a DOS-based configuration environment. This is not a standard general-purpose I/O module. ## Deployment Context in an S7-400 Rack The FM456-4 mounts in a standard rack, connecting via the backplane bus. The /DOS suffix in the description suggests the module may require a DOS-based configuration tool or runtime environment. Power draw and slot assignment follow the backplane specification.","metaTitle":"Siemens 6ES7456-4EY00-0AE1 FM456-4 Application Module, Matur","metaDescription":"Siemens 6ES7456-4EY00-0AE1 FM456-4 application-specific module for S7-400.
