CPU 315-2DP with IM 153-1 DP, profibus node status

madler7872 Posts: 2 Rating: (0)	Hello, This is my first post and I really need some help. I need some sort of FB or SFC to get DP status from my slave IM 153-1 node, 2 remote Danfoss VFD DP nodes, to the 315-2DP CPU, then read them out on my OP 270 with some sort of visualization. Is there a word or bit set when a slave is faulty? I'm sure, but how to do I get this information? Any help would be appreciated, and LAD is my preferred language. Thank You in Advance!

Hello madler7872, You have some options: Using OB86 as explained HERE , In LAD copy the content of LB11 and you also need further analysis if this is occuring/returning fault.Also you need a data base to store all faulty slaves, setting error in case of OB86 and outputing their number with occuring signal. Using SFC51 as explained HERE , it is in STL but it is much easier that the previous method. FB126 as a tool to give information , more information "Diagnostic package PNIODiag for diagnostic evaluation for PROFIBUS DP and PROFINET IO ". In brief, I suggest using SFC51 plus reading THIS Tip. I hope this is what you want, Hamid Hosseini
