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

Short circuit/overload (if parameterised)

Using 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
