Device-defined data type: AB:1756_IF4FXOF2F_Struct_In:I:0
This table includes the device-defined data types created according to the selected communication format when creating the device.
Member Name | Type | Default Display Style | Description |
|---|---|---|---|
Status | INT | Binary | Status data. |
ChanFault | BOOL | Binary | Channel Fault - Collection of individual channel indicators. |
CalFault | BOOL | Decimal | Calibration Fault - Status indicating if any channel has a bad calibration. Bad calibration means the last attempt to calibrate the channel failed with an error and was aborted. |
Underrange | BOOL | Decimal | Underrange - Alarm indicating the channel’s input is less than the minimum detectable input signal. |
Overrange | BOOL | Decimal | Overrange - Alarm indicating the channel’s input is greater than the maximum detectable input signal. |
RateAlarm | BOOL | Decimal | Rate Alarm - Alarm that is set when the input channel’s rate of change exceeds the configured Ch0Config.RateAlarmLimit. Remains set until the rate change drops below the configured limit unless latched via Ch0Config.RateAlarmLatch in the configuration. |
LAlarm | BOOL | Decimal | Low Alarm - Low alarm that is set when the output signal moves beneath the configured low alarm trigger point indicated in the LalarmLimit member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type. This remains set until the input signal moves above the trigger point, unless latched via the ProcessAlarmLatch member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type, or the input is still within the configured alarm deadband AlarmDeadband) of the low alarm trigger point. |
HAlarm | BOOL | Decimal | High Alarm - High alarm that sets when the input signal moves above the configured high alarm trigger point indicated in the HAlarmLimit member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type. This remains set until the input signal moves below the trigger point, unless latched via the ProcessAlarmLatch member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type, or the input is still within the configured alarm deadband (AlarmDeadband) of the high alarm trigger point. |
LLAlarm | BOOL | Decimal | Low Low Alarm - Low low alarm that is set when the input signal moves beneath the configured low low alarm trigger point indicated in the LLAlarmLimit member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type. This remains set until the input signal moves above the trigger point, unless latched via the ProcessAlarmLatch member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type, or the input is still within the configured alarm deadband (AlarmDeadband) of the low low alarm trigger point. |
HHAlarm | BOOL | Binary | High High Alarm - High high alarm that is set when the input signal moves above the configured high high alarm trigger point indicated in the HHAlarmLimit member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type. This remains set until the input signal moves below the trigger point, unless latched via the ProcessAlarmLatch member of the AB:1756_IF4FXOF2F_Struct_In:C:0 data type, or the input is still within the configured alarm deadband (AlarmDeadband) of the high high alarm trigger point. |
Data | REAL | Float | Input channel value reflecting the current signal read from the terminals and scaled into the configured engineering units for the channel. |
