Module Data Types - 1794-IF8I/A
The table below lists and describes module-defined data types for the 1794-IF8I analog input module. It includes information for input (as indicated by an I) and configuration (as indicated by a C).
Module-defined Data Type: AB:1794_IF8I:I:0
Member Name | Type | Default Display Style | Description |
Fault | DINT | Binary | Fault - Used for Input Data Validation 0 = Valid Data 1 = Invalid Data - if the connection to the module has been lost, or if the module has a severe hardware fault, the lower 8 members are set to 1. |
Ch0Data | INT | Binary | Input data for channel 0. |
Ch1Data | INT | Binary | Input data for channel 1. |
Ch2Data | INT | Binary | Input data for channel 2. |
Ch3Data | INT | Binary | Input data for channel 3. |
Ch4Data | INT | Binary | Input data for channel 4. |
Ch5Data | INT | Binary | Input data for channel 5. |
Ch6Data | INT | Binary | Input data for channel 6. |
Ch7Data | INT | Binary | Input data for channel 7. |
CalibrationDone | BIT | Set to 1 after calibration cycle completed. | |
CalibrationBad | BIT | Set to 1 if channel calibration coefficients cannot be saved or read properly. | |
CalibrationMode | BIT | Set to 1 when calibration mode is selected. | |
GeneralFault | BIT | ||
FieldPowerOff | BIT | Set to 1 when the 24V field power fails. The module status indicator flashes when set. | |
PowerUp | BIT | This member is set when the configuration word is all zeros due to reset or a cleared configuration word. The module status indicator flashes when set. | |
Ch0Underrange Ch1Underrange Ch2Underrange Ch3Underrange Ch4Underrange Ch5Underrange Ch6Underrange Ch7Underrange | BIT | Each member is set when its corresponding input channel is below a preset limit defined by the selected configuration. | |
Ch0Overrange Ch1Overrange Ch2Overrange Ch3Overrange Ch4Overrange Ch5Overrange Ch6Overrange Ch7Overrange | BIT | Each member is set when its corresponding input channel is above a preset limit defined by the selected configuration. |

GainOffsetCalibrate | BIT | Holds the High or Low Reference settings you selected on the Input Configuration tab from the Module Properties dialog box. | |
CalibrationClock | BIT | If selected, calibration mode starts and calibration settings for the selected channels are accepted. If clear, the accepted current calibration coefficients are stored to selected channels, applied and calibration mode is exited. | |
QuickCalibration | BIT | If set to 1, calibration coefficient is stored to all related configurations for selected channels. | |
DefaultCalibration | BIT |
