4.3 Diagnosis parameter
4.3.1 Diagnosis
Parameter DIAGNOSIS will contain detailed information of the device, bitwise coded. More than
one message possible at once (as below-mentioned). If MSB of byte 4 is set to 1 than more
diagnose information is available in the DIAGNOSIS_EXTENSION parameter.
The manufacturer specific parameter "DIAGNOSIS_EXTENSION" will contain bitwise coded
more detailed information of the internal status conditions and error conditions of the
PROFIBUS device.
The corresponding GSD file will contain all messages supported by this device - have a look at
the UNIT_DIAG_BIT(i) definitions.
