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:
ƒ Configuration/parameterisation errors
ƒ Open circuit (if parameterised)
By the use of the SFB 52 you can access the diagnostic data of the module anytime. 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 Bits 3 ... 0: Module class, 0101
b
: Analog module
Bit 4: Channel information available
Bit 7 ... 5: 0 (fixed)
2 0 (fixed)
3 0 (fixed)
4 Bit 6 ... 0: Channel type, 73
h
: analog output
Bit 7: 0 (fixed)
5 Number of diagnostic bits output by the module per channel (here 02
h
)
6 Number of channels of a module (here 02
h
:)
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)
