6ES7197-1LB00-0XA0

SIMATIC S7 Y Coupler for Redundant Y-Link

PRODUCT SNAPSHOT

The Siemens 6ES7197-1LB00-0XA0 is a SIMATIC S7 Y coupler used to create a Y-Link between redundant controllers and a subordinate PROFIBUS DP segment. It allows field devices on a shared DP network to remain accessible through the redundant automation-system paths.

The coupler is engineered as part of the complete Y-Link hardware configuration, including compatible interface modules, bus connectors and controller firmware. Proper PROFIBUS addressing, segment timing, grounding and diagnostic handling are essential for dependable high-availability operation.
