J_Bell Posts: 5822 Rating: (411)	Dear SM, I have to tell you that now I am even a bit more confused... because your answer does not comply with your first question... at least in my mind. So if you just want to know if you can put a Y-Link in a S7-300 Rack than the answer is yes, but in this case you can not add any IO Module to the Y-Link directly, this can only be done with other DP Slaves (single sided). A Y-Link has adesignatedlook how the setup of this thing has to look like. You can not put a Y-Coupler into a S7-300 also not together with other I/O Modules. I hope I could answer your questions now. Best regards J_Bell

The Y coupler must be the only module on that drop, i.e., you cannot have a Y coupler combined with I/O modules on the same Profibus-DP drop. The current documentation for the Y-link explains this all very well, and in fact, you should purchase the Y-link as a single order number rather than trying to piece it together out of the various parts.

J_Bell Posts: 5822 Rating: (411)	Dear PLC Engineer, please excuse me but now I am lost. Everybody talks about the same Rack... but for me the Rack is only the backplane ofthe S7-300... there I have no Problem with, but as soon as you would say that you want to have a redundant Head of a ET 200 M and than some IO and after that a Y Coupler, than I have a problem. As said, if you want to have a redundant DP Slave with IO you can use an IM 153-2 in redundant manor, no question. If you want a YLink with additional single sidedDP Slaves on the single PROFIBUS DP Interfaceconnected to the Y Link this is no question too. Please do not mix that up. Best regards J_Bell
