How does the diagnostic text appear in the diagnostic bu󹪜er?
If you want to enter the diagnostic message in the diagnostic bu󹪜er, you must call the SFC 52
(Enter user-speci󹪝c message in the diagnostic bu󹪜er" in the user program. The event number of
the diagnostic message in each case is speci󹪝ed in the input parameter EVENTN. The interrupt
is entered in the diagnostic bu󹪜er with x=1 as incoming and x=0 as outgoing. The diagnostic
bu󹪜er contains the relevant diagnostic text in the "Meaning" column as well as the time of the
entry.
Default setting
The diagnostic interrupt is disabled in the default setting.
11.4 Data error
When do data errors occur?
If new parameters are transferred to the module, the FM 450-1 checks these parameters. If
errors occur during this check, the module reports these data errors.
Wrong parameters are not accepted by the module.
Where are data errors indicated?
The FC CNT_CTRL enters the data errors in DB1 with the error numbers. You can access this data
word via the variable name "DA_ERR_W" in the user program The following table shows the
numbers of the data errors and the signi󹪝cance of these errors.
