Product Overview
The Siemens 6ES7444-1MX00-0XE0 is a communication module designed for the SIMATIC S7-400 programmable logic controller family. As the CP 444 MAP, it enables connection of the S7-400 to Industrial Ethernet networks using the Manufacturing Automation Protocol (MAP) 3.0 architecture. This module is an essential component for integrating legacy S7-400 systems into modern industrial Ethernet environments, and it includes a comprehensive configuration package on CD for straightforward setup.
Built on the robust ISO 8073 class 4 transport protocol, the Siemens 6ES7444-1MX00-0XE0 supports reliable data exchange in demanding factory automation scenarios. Its design focuses on seamless communication between the S7-400 controller and MAP-compliant devices over Industrial Ethernet at speeds up to 10 Mbit/s.

Industry Applications
The Siemens 6ES7444-1MX00-0XE0 is ideally suited for manufacturing environments where MAP 3.0 is the standard communication protocol. Common applications include:
-
Automotive assembly lines integrating older S7-400 controllers with MAP-based robots and inspection systems.
-
Material handling systems that require deterministic data exchange over Industrial Ethernet using the MAP 3.0 architecture.
-
Process control retrofits in facilities where existing MAP 3.0 devices need to be connected to a central S7-400 controller without replacing the entire network infrastructure.
The module’s built-in configuration package simplifies deployment, reducing engineering time during upgrades or new installations.
Compatibility & Integration
The Siemens 6ES7444-1MX00-0XE0 is designed for direct insertion into a SIMATIC S7-400 rack. It communicates over the backplane bus and provides one Industrial Ethernet interface via a 15-pin sub-D connector that automatically switches between AUI and Industrial Twisted Pair (ITP) media. This flexibility enables integration with both legacy coaxial and modern twisted-pair networks. The module supports S7 extended communication, allowing it to exchange data with other S7 stations on the same network. Because it uses the MAP 3.0 protocol, it is compatible with devices adhering to the Manufacturing Automation Protocol stack.
Selection Guide & Purchasing Advice
Before purchasing the Siemens 6ES7444-1MX00-0XE0, verify that your SIMATIC S7-400 system has an available slot and that the backplane can supply the required 5 V DC at up to 3.1 A. The module comes with a configuration CD — ensure your engineering workstation has a CD drive or a way to read the software. For the best value and genuine components, consider sourcing from a trusted supplier like PLC Source PRO. You can find this part and many other industrial automation spares at ubest101 on the web.
Always check the exact revision and firmware version to ensure compatibility with your existing S7-400 system. If you are unsure about the suitability of the Siemens 6ES7444-1MX00-0XE0 for your specific application, consult the product documentation or contact our technical support team.
