Diagnostic data
Since this module does not support an alarm, the diagnostic data serve to provide information on
this module. In the event of an error the corresponding channel LED of the module is lit and the error
is entered in the diagnostic data.
The following errors are registered in the diagnostic data:
• Configuration/parameterisation errors
•Open circuit (if parameterised)
Using SFB 52 you can access the diagnostic data of the module any time. Data set 1 has the
following structure:
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 a missing external supply voltage
Bit 6: 0 (fixed)
Bit 7: Parameterisation error
1 Bit 3 ... 0: Module class, 0b0101: Analog module
Bit 4: Channel information available
Bit 7 ... 5: 0 (fixed)
20 (fixed)
30 (fixed)
4 Bit 6 ... 0: Channel type, 0x73: Analog output
Bit 7: 0 (fix)
5 Number of diagnostic bits output by the module per channel (here 0x02))
6 Number of channels of a module (here 0x02)
7 Bit 0: Channel error, channel 1
Bit 1: Channel error, channel 2
Bit 7 ... 2: 0 (fixed)
8 Channel-specific errors: channel 1:
Bit 0: Configuration/parameterisation error
Bit 2 ... 1: 0 (fixed)
Bit 3: Open circuit
Bit 7 ... 4: 0 (fixed)
9 Channel-specific errors: channel 2:
Bit 0: Configuration/parameterisation error
Bit 2 ... 1: 0 (fixed)
Bit 3: Open circuit
Bit 7 ... 4: 0 (fixed)
10 ... 15 0 (fixed)
