6.2.4 Slave_Diagnosis (SAP60)

6.2.4.1 Diagnostics Processing Sequence

Two buffers are available for diagnostics. The two buffers can have varying lengths. SPC3 always has one diagnostics buffer assigned to it, which is sent for a diagnostics call-up. The user can pre-process new diagnostics data in parallel in the other buffer. If the new diagnostics data are to be sent now, the user uses the ‘New_Diag_Cmd’ to make the request to exchange the diagnostics buffers. The user receives confirmation of the exchange of the buffers with the ‘Diag_Puffer_Changed Interrupt.’

When the buffers are exchanged, the internal ‘Diag_Flag’ is also set. For an activated ‘Diag_Flag,’ SPC3 responds during the next Write_Read_Data with high-priority response data that signal the relevant master that new diagnostics data are present at the slave. Then this master fetches the new diagnostics data with a Slave_Diagnosis telegram. Then the ‘Diag_Flag” is reset again. If the user signals ‘Diag.Stat_Diag =1,’ however (static diagnosis, see the structure of the diagnostics buffer), then ‘Diag_Flag’ still remains activated after the relevant master has fetched the diagnosis. The user can poll the ‘Diag_Flag’ in het status register to find out whether the master has already fetched the diagnostics data before the old data is exchanged for the new data.

Status coding for the diagnostics buffers is stored in the‘Diag_bufferSM’ processor parameter. The user can read this cell with the possible codings for both buffers: ‘User,’ ‘SPC3,’ or ‘SPC3_Send_Mode.’

The ‘New_Diag_Cmd’ is also a read access to a defined processor parameter with the signal as to which diagnostics buffer belongs to the user after the exchange, or whether both buffers are currently assigned to SPC3 (‘no Puffer’, ‘Diag_Puf1’, ‘Diag_Puf2’).
