It handles USS and ASCII protocols as library functions in TIA Portal, and supports Freeport programming for custom serial links. The single RS-422/485 interface is on a 9-pin D-sub (male) – watch the pinout if you are replacing a standard unit, the connector orientation is the same. Power draw is typical 1.2 W from the 24 V DC backplane; the supply can sag to 20.4 V and still hold the module up. Mechanical footprint is a slim 30 mm wide by 100 mm high by 75 mm deep – sits on standard DIN rail and leaves room for adjacent modules. Cable length to the remote device can run up to 1 000 m, but at that distance shield grounding matters: single-point on the D-sub shell at the module end keeps ground loops out of the RS-485 bus. The module is designed for altitudes up to 5 000 m with derating above 2 000 m; at sea level expect full 70°C ambient tolerance. Drop height rating is 0.3 m in the package – treat the conformal coating as environmental protection, not impact armor. The lifecycle status is active – no last-time-buy or NRND flag. This part ships with the conformal coating already applied and the standard TIA Portal GSDML; no special firmware or library pack beyond what the base module uses.","metaTitle":"Siemens 6AG1241-1CH32-4XB0 SIPLUS CM 1241 RS-422/485 Module","metaDescription":"Active production SIPLUS communications module based on 6ES7241-1CH32-0XB0 with conformal coating.
