good evening all , i need advice . i have a project in which there a lot of danfoss fc302 drives connected in profibus to s7317-2pn/dp . even after downloading OB86 , the plc is going into stop mode whenever any one of the drive is powered off . is there any way to avoid this issue . the project is for a process factory which cannot afford plc going in to stop mode whenever a drive goes off .

Hello, Do you still read and write to the drive that is disconnected? Best regards, Wizard |

Thanks for the advice dchartier . i figured out where i went wrong and now the plc is fine .instead of going to stop mode there are sf and bf led on . the other issue i started facing is i added Ob32,40,82,83,5,86,87,121,122 to the program . when i compiled the charts all the ob's got deleted automatically . so i added all the ob's to a s7 tasklist .but after compiling and downloading , plc goes to stop mode only when drive comm is lost .if the et200s station is lost only sf and bf comes on. i have added the diagnose txt . if you could guide where am making mistake it would be great AttachmentDiagnose.txt (583 Downloads) |
