Fault and Status Reporting
The PointMax analog HART I/O module sends fault and
status data for HART device, configured dynamic variables, and device variables in the
producer data for each HART device.
Data Type | Tag Name | Triggering Event That Sets the Tag |
|---|---|---|
Fault | ConnectionFaulted | The owner-controller loses its connection to the module.
TIP:
This tag provides module-wide
data and affects all channels simultaneously.
|
CurrentMismatch | The HART digital value does not match the analog module channel
value. | |
Malfunction | The device has detected a hardware error or failure. | |
<NameOfVariable>.Ch.Fault | Data is inaccurate and cannot be trusted for use in the
application. | |
<NameOfVariable>.Ch.Underrange | The input signal at the channel is less than, or equal to, the
min detectable signal. | |
<NameOfVariable>.Ch.Overrange | The input signal at the channel is greater than, or equal to, the
max detectable signal. | |
Static.Fault | Indicates if the set of static data is valid. For PlantPAx
connection only. | |
Status | RunMode | The module is in Run mode. |
DiagnosticActive | Indicates if any diagnostics are active or if the prognostics
threshold is reached. | |
DiagnosticSequenceCount | A counter that increments when a diagnostic condition occurs or
goes away. The counter is a rolling counter that skips 0 on
rollovers. | |
CurrentSaturated | The loop current has reached its upper (or lower) endpoint limit
and cannot increase (or decrease) any further. | |
CurrentFixed | The loop current is being held at a fixed value and is not
responding to process variations. | |
MoreStatusAvailable | More status information is available than can be returned in the
Field Device Status. | |
ConfigurationChanged | HART device configuration is changed and the module has retrieved
all HART device configuration data to be returned by the Get
HART Device Information service. | |
<NameOfVariable>.Ch.Uncertain | Indicates that the channel data can be inaccurate but the degree
of inaccuracy is not known. | |
<NameOfVariable>.Ch.Data | The last good value received from the device. | |
<NameOfVariable>.Ch.RollingTimestamp | RollingTimestamp is continuously running a 15-bit timer that
counts in milliseconds. | |
<NameOfVariable>.Class | Device Variable Classification | |
<NameOfVariable>.Unit | Unit code | |
<NameOfVariable>.Manual | Indicates that the data value is manually controlled. | |
<NameOfVariable>.Constant | Indicates that the data value is constant. It is set to 1 when
variable status indicates constant. | |
Static.PVUnit | Unit code of PV. For PlantPAx connection only. | |
Static.HARTRevision | HART protocol major revision number. For PlantPAx connection
only. | |
Static.HARTTagName | Assigned name of HART device. Same as Identity attribute 15. For
PlantPAx connection only. | |
Static.Descriptor | Descriptor of HART device. For PlantPAx connection only. | |
Static.PVAtSignal4 | PV Lower Range value. For PlantPAx connection only. | |
Static.PVAtSignal20 | PV Higher Range value. For PlantPAx connection only. | |
Static.AdditionalDeviceStatus | Additional Device Status from HART command 48. For PlantPAx
connection only. | |
ChDataAtSignal4 | This member is the engineering unit value of 4 mA according to
the corresponding analog input channel configuration of the
module. For PlantPAx connection only. | |
ChDataAtSignal20 | This member is the engineering unit value of 20 mA according to
the corresponding analog input channel configuration of the
module. For PlantPAx connection only. |
