Hello, You should add Y-link (153-2BA02) and in case of 400H CPUs automatically will connect to both CPUs. On the same time you will receive a message to define a master system with two options - lake a Profibus DP or Profibus PA. Select it like a DP master. There you can connect the non profibus redundancy DP devices to a redundant DP line. Now about DP/PA Link - It creates a gateway from a PROFIBUS DP master system to a PROFIBUS PA master system. Because (most probably you Profibus baud rate is higher then 45.45 Kbaud) there is required a DP/PA link. The DP/PA link resets the higher transmission rate of PROFIBUS DP on its backplane module to 45.45 Kbaud and passes it on to the DP/PA coupler. You only have to configure the interface module of the DP/PA link. The DP/PA coupler is not configured.( How is the DP/PA link structured? ). So, put in hardware configuration one DP/PA link. And put after it all the PA devices. Best regards, Hristo Mihalev |
