In my enthusiasm/time crunch, I neglected to consider the fact that my USB -- MPI/PROFI adapter only communicates at 1.5 Mbit whilst I had configured the PLC (315T-2DP) to run 12 Mbit Profi on both DB-9 connections. The hardware configuration was successfully transmitted. So now I apparently have no way of changing the PLC back, or communicating with it in general. . . unless someone knows of a way to do it without use of the adapter. Is there some method to remedy this mistake? Thanks, The Captive Engineer

These would be the two ways I see... Best regards. J_Bell
