Hello all. Has anyone done a Profibus master-slave communication in TiA portal? I am trying to do it with a CPU315-2DP(new plc) as the master and an old CPU314-2DP(V 2.0.12) as the slave. But I can't seem to get it to work. The Slave PLC has the following errors (check the attached diagnostics log). But I guess that this is the problem: Distributed I/Os: End of the synchronization with a DP master/IO controller on slot 2 Number of distributed stations: 0 Is there anything specific that I have to set in order for the communication to work? I have set the transfer areas on the slave PLC, other than that I don't know what else to set. Could it be that the PLC firmware is too old for this to work? The current firmware is:V 2.0.12 Cheers. ------------------------------------------------------------------------------------------ AttachmentDiagnostics.txt (119 Downloads) |

Hello. Is it possible that the CPU goes to STOP because there is no SFB20 loaded on the PLC? Cheers |
