Device-defined data type: AB:1756_IF4FXOF2F_Struct_Out: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 | Decimal | Channel Fault - Collection of individual channel indicators. |
CalFault | BOOL | Decimal | Calibration Faul t - 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. |
WireOff | BOOL | Decimal | Wire Off - Diagnostic that detects that a wire was disconnected from the channel. If a group of channels all show this fault, then possibly the return (L1 or GND) is missing from the device. Only available in the 0 to 20 milliamp output range.
|
NotANumber | BOOL | Decimal | Not A Number - Indicates whether the last channel data received was a number or not a number.
|
InHold | BOOL | Decimal | In Hold - Indicates if the output channel is currently holding until the output value sent to the device (O data type, Ch0Data member) matches the current output value (I data type, Ch0Data member) within 0.1% of the channel’s full scale. |
RampAlarm | BOOL | Decimal | Ramp Alarm - Alarm that is set if ramping is enabled in run mode, Ch0Config.RampToRun is set, and the difference between the new output value requested and the current output exceeds the configured ramp limit, Ch0Config.MaxRampRate. The alarm remains set until ramping ceases unless it is latched by Ch0Config.RampAlarmLatch. |
LLimitAlarm | BOOL | Decimal | Low Limit Alarm - Alarm that is set when the requested output value, Ch0Data, is below the configured low limit, Ch0Config.LowLimit. The output stops at the configured low limit, which the echo reflects. The alarm remains set until the requested output moves above the low limit unless it is latched by Ch0Config.LimitAlarmLatch. |
HLimitAlarm | BOOL | Decimal | High Limit Alarm - Alarm that is set when the requested output value, Ch0Data, is above the configured high limit, Ch0Config.HighLimit. The output stops at the configured high limit, which the echo reflects. The alarm remains set until the requested output moves below the high limit unless it is latched by Ch0Config.LimitAlarmLatch. |
Data | REAL | Float | Output value in engineering units that the channel is requested to take by the control system. The output signal transitions to the requested value unless the device is in Program mode or currently being calibrated. The signal snaps to the requested value unless ramping or the value is beyond the configured channel limits in the LowLimit and HighLimit members of the AB:1756_IF4FXOF2F_Struct_Out:C:0 data type. |
