Dear Fellow Siemens User,

Good day may I ask if 6ES7195-7HA00-0XA0 can be used as bus module for DP/PA Coupler in redundant IM153-2. PA side is no problem as I can detect it if I directly connect to the Main profibus Line but if connected to IM153-2 it cannot see the PA devices. IM153-2 can be see as active indicator is on.

Best regards,

Reymond

Hello Reymond;

First, this FAQ can give you a lot of information on the cative bus couplers you can use with DP/PA Links and Y-Links:

Which active backplane bus modules do you need when using the DP/PA link or Y link?

However, could you take a few seconds to explain what you want to do, exactly?

If you want to create a redundant DP/PA link, you need to use active bus couplers for the 2 IM-153-2 and the DP/PA couplers also. Look at the second link at the bottom on the link I proposed. This configuration is explained at the end of the DP/PA link article.

Further information about the structure

• You can find a Y link in Entry ID: 43688632.
• You can find a DP/PA link in Entry ID: 51678187.
  

Hope this helps,

Daniel Chartier
