Diagnostic alarm processing:
Using SFB 52 you can read out the diagnostic bytes. If the diagnostic alarm is deactivated,
you can access the last diagnostic event in each case.
If you have activated the diagnostic function in your hardware configuration, OB 82 is
called automatically. Here you can react on the diagnostics accordingly. With the SFB 52
you can additionally read out data set 1 which contains further information.
After exiting OB 82, the data ca no longer be clearly assigned to the last diagnostic alarm.
Data set 1 is structured as follows:
Data set 1, diagnostics
incoming
Byte Bit 7 ... 0
0 Bit 0: Set in the case of module fault
Bit 1: Set in the case of internal error
Bit 2: Set in the case of external error
Bit 3: Set if channel error available
Bit 4: Set in the case of missing external supply voltage
Bit 6 ... 5: 0 (fixed)
Bit 7: Parameterisation error
1 Bit 3 ... 0: Module class, 1000
b
: function module
Bit 4: Channel information available
Bit 7 ... 5: 0 (fixed)
2 0 (fixed)
3 Bit 5 ... 0: 0 (fixed)
Bit 6: Process alarm lost
Bit 7: 0 (fixed)
4 Bit 6 ... 0: Channel type, 76h: counter module
Bit 7: 0 (fixed)
5 Number of diagnostic bits output by the module per channel (here 08
h
)
6 Number of channels of a module (here 01
h
)
7 Bit 0: Error in channel group 0
8 ... 15 0 (fixed)
Data set 1, diagnostics
outgoing
After the error recovery a diagnostic message
outgoing is effected
