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:

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".

Cause
S
An unconfigured AS-i slave was
detected.
S
Error involving a configured (entered in
the LPS) AS-i slave, for which no I/O
module was inserted in HW Config.
AS-i master detects a problem in the power
supply (for example wire break).
The AS-i slave signals an error on the slave
periphery.
AS-i master detects ground short on the
AS-i line.
AS-i master detects "No connection" on the
Ethernet port.
