Standarddiagnostic 12Diagnosticdetail1) Standard diagnosticThis is an array of 6 bytes, with standardized content.2) Diagnostic detailThese bits are available for the process sequence and for displaying on SCADA orHMI.Bit 3 is used to indicate if additional information is available in an extended diagnostic,specific to each device.Reminder: The block allows you to get both standard and extended diagnostics;these are executed by an explicit request.For the TSX PBY100 master, a DFB PROFIBUS_DIAG_REQ has been designedwhich uses the SEND_REQ function to read the diagnostics.For the PTQ_PDPMV1 master, a DFB GETDIAGNOSTICS has been designed whichuses the Mailbox function to read the diagnostics.For the MNET5204 master, a DFB GET_SLAVE_DIAGNOSTICS has been designedwhich uses the Mailbox function to read the diagnostics.For the PTQ_PDPMV1 and MNET5204 masters, there is an alternate method ofusing the standard diagnostic only. Diagnostic zones must be declared using theProfibus configuration software. This method has the disadvantage of holding passbandon communication.49
