It provides one RS-422/485 port (D-sub 9-pin male) for Freeport, USS, or ASCII communication via library function blocks — the standard choice for drive links or serial instrument chains on a 1200 CPU. The module draws 240 mA at 24 VDC from the backplane bus (L5+ logic) — a light load that leaves headroom for additional I/O on the same CPU power budget. Typical power loss is 1.2 W, so no derating curve worries in a crowded cabinet. USS and ASCII are supported as library functions, not built-in hardware — you add the function block in TIA Portal. No extra protocol charge; it's part of the standard library. ## Sourcing and lifecycle standpoint No direct replacement announced — this is the current ruggedized version for the CM 1241 RS-485 slot. If you're holding a 6ES7241-1CH31-0XB0, this is the drop-in conformal-coated upgrade.","metaTitle":"6AG1241-1CH31-2XB0 SIPLUS S7-1200 CM 1241 RS-485, -40..70°C","metaDescription":"SIPLUS CM 1241 RS-422/485 communications module for S7-1200, conformal coated, -40 to +70 °C, current production.
