9 Diagnostics
This chapter...
The chapter explains the errors on the AS-Interface to lead to alarm messages.
9.1 Overview
The IE/AS-i LINK provides you with two diagnostic options:
S Interrupts and their subsequent evaluation
S Reading diagnostic data records by the PROFINET IO controller
Access mechanism
Refer to the manual of your PROFINET IO controller for information on the
mechanisms for using diagnostics with the PROFINET IO controller.
Since STEP 7 system diagnostics supports the reading of channel diagnostic
information for all submodules of PROFINET IO devices, there is already
diagnostic integration in STEP 7.
The system function block SFB 54 is available for receiving interrupts. For
information on SFB54, refer to the block helps of STEP 7.
9.2 Interrupts
Interrupts can divided into the following groups:
S Remove/insert module interrupts
Remove/insert module interrupts can be evaluated in the S7 user program
using OB83.
S Diagnostic interrupts
Diagnostic interrupts can be evaluated in the S7 user program using OB82.
9.2.1 Remove/Insert Module Interrupts
Remove/insert module interrupts are signaled over the logical I/O address or
diagnostic address of the relevant slot (slot 1−63, 101−163).
Notice
The IE/AS-i LINK only signals remove/insert module interrupts when the IE/AS-
i LINK is operating in protected mode.
