What this module is and what it brings
The Siemens 6AG1241-1CH32-2XB0 is the SIPLUS CM 1241 communications module for the S7-1200 PLC series, based on the standard 6ES7241-1CH32-0XB0 with added conformal coating and an extended operating temperature range of -40 to +70 °C. It provides a single RS-422/485 (X.27) interface via a 9-pin D-sub (male) connector and supports USS and ASCII protocols as library functions within TIA Portal.
Sourcing and lifecycle – still an active BOM line
This SIPLUS variant is listed as active (current production) per Siemens lifecycle tracking. It is available to order against an RFQ; no discontinuation or last-time-buy date is posted. For a BOM line requiring the conformal coating or extended temperature range, this is the direct replacement for the standard CM 1241 in harsh environments.
