You have the option of reading the diagnostics functions in the standard program by calling
SFB 52 or SFB 54. For detailed information, refer to the "System and Standard Functions"
reference manual.
Diagnostics of PROFIsafe errors
When diagnosing PROFIsafe errors, address the "DIAG" variable of the F-I/O DB. Detailed
information about the F-I/O-DB can be found in the Programming and operation manual "S7
Distributed Safety - Configuring and Programming"
HMI device with a serious error
If a serious error in the HMI device leads to its failure, the HMI device reacts as follows:
● The connection to PROFINET will be interrupted and the fail-safe channels will be
rendered passive.
● No diagnosis will be transmitted from the HMI device.
In STEP 7 in module diagnostics, the standard diagnosis "Module interrupted" or "Module
missing" will be reported.
