What this package does for the S7-300 rack
The Siemens 6ES7351-1AH00-7EG0 is the configuring package for the FM 351 positioning module — the software and parameterization tool that sets up the module's cam and position control for the S7-300 PLC. Without this package, the FM 351 hardware sits on the rack without the motion profile it needs to run.
Lifecycle reality — eol_hot means time is tight
For a cement plant or any continuous-process line running an FM 351, this is the moment to secure a spare copy of the configuration tooling before it dries up entirely. Sourced through independent distribution against an RFQ; availability confirmed at quote time.
What it connects to in the S7-300 ecosystem
This configuring package is the software companion to the FM 351 positioning module — it does not plug into the rack itself. The FM 351 module snaps onto the S7-300 DIN rail and communicates via the backplane bus; this package provides the parameterization data the module needs to execute cam and positioning sequences.
