Product details

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. 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.

Frequently asked questions

What temperature range does this module support?

Operating ambient is -40 to +70 °C, with startup from -25 °C. Derating applies at high altitudes per the altitude-pressure table.

Does this module support USS or ASCII protocol out of the box?

USS and ASCII are available as library functions in TIA Portal, not as built-in protocol stacks. You add the library to your project to use them.
