6ES7441-1AA05-0AE0 SIEMENS Exclusive SIMATIC S7-400 CP 441-1 Coupling Module Original Brand New

The SIEMENS 6ES7441-1AA05-0AE0 CP 441-1 is a reliable coupling module designed for fast and high-performance serial communication via point-to-point connection in SIMATIC S7-400 systems. This original brand new module includes one variable interface and comes complete with a configuration package on CD, ensuring smooth deployment and integration.

As part of the SIMATIC communication module series, this unit allows serial data exchange using various physical transmission standards such as RS 232C (V.24), 20 mA (TTY), or RS 422/RS 485 (X.27). Implemented protocols include ASCII, 3964(R), and a printer driver. The module is especially suited for industrial setups requiring stable, isolated, and flexible data communication.

Overview

The CP 441-1 enables simple and effective serial communication with one variable interface. Siemens also offers the CP 441-2 variant with two variable interfaces for more complex point-to-point operations. Compatible protocols include ASCII and 3964(R), while the CP 441-2 adds support for RK 512 and Modbus RTU (loadable). Parameter assignment is streamlined using the STEP 7 integrated programming tool.

Plug-in modules allow flexibility in transmission modes, and the module can be installed in central or expansion racks with guaranteed K bus signal continuity.

Design

This communication module features a rugged plastic enclosure built for industrial durability. Design highlights include:

• LED indicators for Send, Receive, and Error status
• Slot for plug-in interface module (1 for CP 441-1, 2 for CP 441-2)
• Support for RS 232C, RS 422/485, or 20 mA (TTY) transmission
• Compatibility with STEP 7 for configuration and diagnostics

Drivers

For the CP 441-2, various loadable drivers are supported:

• Modbus: Supports Modbus RTU communication in master-slave configurations
• Each serial interface operates independently using standard or loadable protocols
