	Y-Link		6ES7 197-1LA11-0XA0	B)
	For connection of devices with
	only one PROFIBUS DP interface
	to a fault-tolerant automation sys-
	tem, comprising:
	• 2 IM 153-2 High Feature inter-
		face modules
	• 1 Y-coupler
	• 1 BM IM 157 bus module (IM/IM)
	• 1 BM Y-coupler bus module
		PS 307 load power supply
		Including connection assembly;
		120/230 V AC; 24 V DC

		• 5 A, extended temperature	6ES7 307-1EA80-0AA0
		range; 80 mm wide

The Y-link is a bus coupler for transition from a redundant PROFIBUS DP master system to a single-channel PROFIBUS DP master system. It can be used for connecting de- vices with only one PROFIBUS DP interface to the redundant PROFIBUS DP master system AS 414H/ AS 417H.

redundant PROFIBUS DP

Fault-tolerant automation system

Y-Link

Connection of non-redundant PROFIBUS DP devices to redundant PROFIBUS DP

B) Subject to export regulations: AL: N, ECCN: EAR99H

The Y-link comprises:

•Two IM 153-2 High Feature interface modules for extended temperature range

•One Y-coupler incl. RS 485 repeater

•One IM 157 (IM/IM) bus module for two IM 153-2 High Feature modules, for extended temperature range

•One BM Y-coupler bus module

Evaluation of the Y-Link diagnostics (and hence indirectly of the connected DP standard slaves) is supported by driver blocks.

It is recommendable to have a redundant -24 V DC supply for the Y-Link, e.g. with two PS 307/PS 305 load power supplies.
