However I search in Google, it seems nothing can be find. If anyone knows the diagnostic info structure, please tell me. Best regards. KS

There is a link on every SSL-ID. ------------------------------------------------------------------------------------------------------- Header The header of partial list SSL-ID W#16#00B4 is structured as follows: Contents Meaning SSL-ID W#16#00B4 INDEX Configured diagnostic address of the DP slave LENTHDR Length of a data record. The maximum length is 240 bytes. For standard slaves which have a diagnostic data length of more than 240 bytes up to a maximum of 244 bytes, the first 240 bytes are read and the overflow bit is set in the data. N_DR 1 Data Record A data record of partial list SSL-ID W#16#00B4 has the following structure: Name Length Meaning status1 1 byte Station status1 status2 1 byte Station status2 status3 1 byte Station status3 stat_nr 1 byte Master station number ken_hi 1 byte Vendor ID (high byte) ken_lo 1 byte Vendor ID (low byte) .... .... Further diagnostic data specific to the particular slave ------------------------------------------------------------------------------------------------------- Regards, yy1
