Evaluation of the diagnostic information
Detailed diagnostic information can be evaluated in SIMATIC S7 using
SFB54 ”RALRM” with the block parameter AINFO. You will find the interrupt
structure in the documentation or the help on SFB54. The link-specific significance
of the error types (AINFO, bytes 32−33) is described below.
Errors that trigger a diagnostic interrupt on the AS-i line
The following errors cause diagnostic interrupt:

9.3 Diagnose Data Records
Further diagnostic information can be read out from the IE/AS-i LINK using the
data record interface (Section 8.2) for example “Get_LPS_LAS_LDS_LPF_Flags”
or “Read_and_delete_AS-i_Line_Errorcounters”.
