Siemens 6ES7444-1MX00-0XE0: MAP 3.0 Industrial Ethernet Communication Module

Bridge your S7-400 to legacy manufacturing networks. The Siemens 6ES7444-1MX00-0XE0 (CP 444) is a specialized communication processor. It implements the full Manufacturing Automation Protocol (MAP) 3.0 architecture over 10 Mbit/s Industrial Ethernet, enabling integration with older MAP-based factory systems and host computers.

Core Function & System Integration Role

• Legacy Protocol Gateway: Provides dedicated connectivity for MAP 3.0 networks, a standard in 1980s/90s automated manufacturing.
• Industrial Ethernet Physical Layer: Uses robust 10 Mbit/s Ethernet with AUI or twisted-pair (ITP) connectivity for plant floor durability.
• Reliable S7 Communication: Supports S7 extended communication for data exchange within Siemens automation systems over the MAP network.
• Complete Configuration Suite: Includes the necessary configuration package on CD for setup within the S7-400 environment.

Expert FAQs for Application

• What kind of systems typically used MAP 3.0?
  MAP was widely used in automotive and discrete manufacturing for cell controller and host computer communication. This module allows modern S7-400 PLCs to integrate into such existing, legacy backbone networks.
• Can it connect to standard IEEE 802.3 Ethernet networks?
  Physically, yes, via the AUI port with a transceiver. However, it only communicates using the MAP 3.0 protocol stack, not standard TCP/IP. It is not for connecting to IT networks or the internet.
• What is the "S7 extended communication" it provides?
  This allows the S7-400 CPU to communicate with other Siemens devices (like older S5 PLCs via suitable gateways) over the MAP network using native S7 services for data block exchange.
• Why does it consume significant power from the backplane?
  The 3.1A draw reflects the computational power needed to process the complex, multi-layered MAP 3.0 protocol suite in real-time on the module's own processor.
• Is this module still relevant for new projects?
  Primarily for modernization and maintenance. It's a strategic solution for extending the life of existing MAP-based factory networks by connecting new S7-400 controllers without replacing the entire network infrastructure.
