The Siemens 6ES7452-1AH00-7CG0 is a configuration package for the FM 452 cam controller — essentially the software/parameterization medium that sets up the cam-switching profiles on a SIMATIC S7-400 system. Its lifecycle stage is listed as mature, meaning it is no longer in the active new-design phase but remains available through the supply channel for installed-base support.
No last-time-buy window is in effect.
The description reads 'Configuration package FM 452 (f)'. The '(f)' indicates the firmware variant — likely the standard German/European firmware release. This matters if your existing FM 452 module expects a specific firmware revision for the cam data upload; mixing firmware versions between the configuration package and the module can cause parameterization mismatches.
