More information about the diagnostics data may be found in the System
SLIO manual HB300_FM_050-1BA00.
n
On an error the faulty system generates a diagnostics message for the CPU. Then
the CPU calls the according diagnostics OB. Here the CPU operating system trans-
fers start information to the local data of the OB.
n
By evaluating the start information of the according OB you can get information about
cause and location of the error.
n
During runtime you can access the start information with the system function SFC 6
RD_SINFO.
n
Please consider that you can even read the start information in the OB himself,
because the data are temporary data.
Depending on the type of error, the following OBs are called in a diagnostics event:
n
OB 82 on an error of an module at the IO device (Diagnostics interrupt)
n
OB 83 on inserting respectively removing a module on a IO device
n
OB 86 on failure respectively return of a IO device
More information about the OBs and their start information may be found
in the online help of your programming tool and in the manual "SPEED7
Operation List" from VIPA.
The PROFINET IO controller does not have any physical LEDs to show the status. The
status information are stored as virtual LED states. During runtime, you can determine
their status using the SSL partial lists xy19h or xy74h. More can be found in the manual
operation list (HB00_OPL_SP7) of your CPU.
