Hi, you can use the Functin Block "DL_WriteNode" out of the "CXA_Datalayer" Library. Call the FB with " DL_WriteNode.NodeName:= 'diagnosis/confirm/all-errors', " and set the "DL_WriteNode.Execute" on TRUE when you want to reset the Errormessages on the Core. Set the Execute on False with "DL_WriteNode.Done" or "DL_WriteNode.Error". Short Example out of my Code: VAR fbPLC_Reset :DL_WriteNode; END_Var fbPLC_Reset( Execute:= , Done=> , Active=> , Error=> , ErrorID=> , ErrorIdent=> , ClientId:= , NodeName:= 'diagnosis/confirm/all-errors', // "global clear error" Funktion in ctrlX Datalayer Value:= ); IF GVL_IO.E15_reset OR GVL_HMI.bReset THEN fbPLC_Reset.Execute:=TRUE; ELSIF fbPLC_Reset.Done OR fbPLC_Reset.Error THEN fbPLC_Reset.Execute:=FALSE; END_IF
