we have s7-400 (pcs-7,ver.6.1) plc with 417cpu and 4 cp for four different profibus routes with min 60 nodes on each route. we have got problem of link failure during running plant and got whole plant stoppage.
we used 1.5mbps speed on data transfer.
can anybody tell me that which type of care/maintenance should be done with profibus to prevent this failure?
how may repeaters we can use in one line and how may instrument earthing we can done in one route?
