What this FM 355 configuring package is
The Siemens 6ES7355-0VH10-7BE0 is a configuring package for the FM 355 (e) controller module, part of the PLC I/O & Expansion Modules family. It provides the software or parameter set to commission the FM 355 loop controller in a SIMATIC S7-300 rack.
Lifecycle reality — EOL, no successor on record
Sourcing goes through independent distribution channels. Availability is lot-specific and confirmed at RFQ; there is no factory stock or manufacturer lead time to rely on. If this is a BOM line for a legacy S7-300 installation, securing a spare copy before the current one fails is the prudent move.
The FM 355 (e) is a closed-loop controller used for temperature, pressure, flow, and level control in process applications. This configuring package contains the engineering tool or parameterization data needed to set up the FM 355's control loops, alarms, and monitoring functions from a STEP 7 environment.
