The Siemens 6ES7444-1MX00-7BG0 is a configuration package CP444, included in the scope of delivery of the CP 444 MAP as of October 1, 2001. This is not a standalone CP 444 module but the configuration package that accompanies it — the software or parameterization bundle that sets up the MAP (Manufacturing Automation Protocol) interface on a SIMATIC S7-400 rack.
What the Description Means for Fit
The German description 'Configuration package CP444 (e) ab 01.10.2001 IM LIEFERUMFANG DES CP 444 MAP ENTHALTEN' translates to: the CP444 configuration package has been included in the scope of delivery of the CP 444 MAP since October 1, 2001. If you are sourcing a replacement or spare for a legacy S7-400 system that uses MAP (Manufacturing Automation Protocol) for factory-floor communication, this is the software/configuration bundle that originally shipped with the CP 444 hardware. It is not the hardware module itself — verify your BOM line expects the configuration package, not the CP 444 communications processor.
