It is important to ensure that the corresponding bit is set in at least one of the
assignment parameters for each event group. Otherwise no category will be
transmitted with the event over the bus, and the control system will therefore
generally ignore the presence of the event.
The detection of diagnostic events is parameterized with the MAP parameters (F, C, S,
M) but the transmission of messages over the bus is not. The latter is done with the
MASK parameters. The Resource Block must be in the Auto mode for the status
information to be transmitted over the bus.
14.7.3 Configurable area
The event category can be individually defined for the following events - irrespective of the
event group they are assigned to in the default setting:
• 042: Sensor corrosion
• 103: Drift
• 901: Ambient temperature too low
• 902: Ambient temperature too high
To change the event category, the event first has to be assigned to one of the bits 1 to 15.
The ConfigArea_1 to ConfigArea_15 parameters in the ADVANCED DIAGNOSTIC
(ADVDIAG) Block are used for this. Then the corresponding bit can be set from 0 to 1 in
the desired assignment parameter.
Example
The diagnostic event 103 "Drift" should no longer be categorized as Maintenance required
(M) and should be categorized as Out of Specification (S) instead. Furthermore the status
of the measurement value should display BAD in this case.
1. Navigate to the Advanced Diagnostic Transducer Block and the
CONFIGURABLE_AREA parameter.
 In the default setting, all bits in the Configurable Area Bits column have the value
"not assigned".
