The Siemens 6ES7444-1MX00-7AG0 is a configuration package for the CP444 communications processor used in SIMATIC S7-400 systems. It was included in the delivery scope of the CP444 MAP starting October 1, 2001.
What the Lifecycle Stage Means for Fit
A mature lifecycle stage signals that Siemens has shifted focus to later S7-400 revisions or to the S7-1500 platform. If you are maintaining an existing S7-400 line with a CP444, this configuration package is the correct software component. For new designs, evaluate the current CP444 firmware version or consider migration to a newer communications processor.
