It handles ASCII, 3964 (R), and RK 512 protocols at speeds up to 115.2 kbit/s on both channels simultaneously. Each channel is independently configurable, so one port can run an ASCII printer while the other talks to a drive, for example. The module draws up to 700 mA from the 5 V backplane bus without its interface submodule. ## Protocol support and printer driver The CP 441-2 supports S7 extended communication, STEP 7 parameter assignment, and reloadable customer-specific drivers. Memory requirements per interface range from 1 to 5 KB for parameters, 0 to 55 KB for message texts, and 0 to 64 KB for loadable drivers on the CPU memory card. Built-in printer drivers cover HP-Deskjet, HP-Laserjet, and IBM-Proprinter models, plus user-defined types, with a maximum transmission rate of 115.2 kbit/s. This makes it suitable for logging process data directly from the S7-400 rack to a local printer without an intermediate PC. The 6ES7441-2AA03-0AE0 is available to order against RFQ through independent distribution channels.","metaTitle":"Siemens 6ES7441-2AA03-0AE0 CP 441-2, 115.2 kbit/s","metaDescription":"Siemens SIMATIC S7-400 CP 441-2 communications module, two channels, 115.2 kbit/s, mature lifecycle.
