Configuring package for FM 355 — what it is
The 6ES7355-0VH00-7AE0 is the configuring package for the Siemens FM 355 (g) — a software/parameterization tool, not a field device or I/O module. It is used to set up and commission the FM 355 closed-loop controller, typically during the engineering phase of a SIMATIC S7-300 system.
Lifecycle signal — eol_hot
No official successor order code is recorded for this configuring package. If the FM 355 is still in service, the configuring package may still be needed for commissioning or re-parameterization of existing units — but new projects should plan for the current-generation controller platform.
Sourcing reality for an eol_hot part
Because the lifecycle stage is eol_hot, this part is sourced through independent distribution channels — quoted to order against the BOM quantity. For MRO planners or storeroom keepers who need this configuring package to support an installed FM 355 base, the key action is to verify the exact version compatibility with the existing controller firmware before ordering — the configuring package is tied to the FM 355 (g) variant.
