Dear 315-2DP the "inserted module and configured model aren't identical" message for your DP Slave is a worry (on the bright side, until this is solved there is no need to worry about the SFC14 W#16#80A0 error, which cna very well be explained by this problem). One of the "jobs" of a (Class 1) DP Master (theS7 PLC in your case) is to parameterise and (I/O) configureeach DP Slave on bus startup (e.g. after HWconfigdownload, power failure of Slave or Master etc.). Once done with this, the DP Master will "check" (via a Diagnostic request message) if the parameterisation and configuration was succesful (which does not appear to be case here). Example: Let's say you have an"ordinary" DP Slave such as an ET200M I/O station and physically pluggedfour 32 channel DI cards into it. Inyour HWconfig however youconfigured three 32 channel DIcards and one 32 channel DQcard. This mismatch will lead to the same problem that you observe. I unfortunately have no experience with your DIRIS A40 DP Slave, but whateverI/O config you do in your HWconfig will need to be supported by the DP Slave. You said before that you were able to read 4 bytes from the DP Slave, so I assume that the node address is ok and that the bus in general is ok too. As such, I suggesttocheck the DIRIS manual and/or the supplier to find outmore about possible/supported I/O configurations and reasons for the observed problems. By the way, you'll find a wealth of free helpful manualsconcerning Profibus at www.profibus.comwhich I hope will come in handy one day. Good luck andkeep us posted |
