Siemens SIMATIC ET 200SP AS-i Master F-Link Communication Module CM AS-i, 6ES7137-6AA01-0BA0

The Siemens CM AS-i module stands out by integrating safety monitoring directly into the AS-i master, eliminating the need for a separate safety controller in SIMATIC ET 200SP systems. This single-width module handles both standard and safety-related AS-i communication, reducing hardware footprint and simplifying wiring for distributed automation.

Highlights

• Integrated safety monitor for safe AS-i communication
• AS-Interface V3.0 with single address mode
• 12 bytes data width per module, 5 ms cycle time
• Hot-swappable via ET 200SP BaseUnit type A0
• Diagnostics for AS-i faults, short circuits, and overload

In daily use

Mounted on a DIN rail through an ET 200SP BaseUnit, the module connects to the backplane bus for power and PROFINET/PROFIBUS communication. The front AS-i port connects to the yellow AS-i cable, and configuration is done in TIA Portal. The integrated safety monitor enables safe communication with AS-i safety slaves, supporting functional safety without extra hardware. The module consumes a maximum of 100 mA from the 24 V DC backplane bus and operates from 0 to 60 °C, suitable for control cabinets with IP20 protection.
