Module Data Types - 1794-IE4XOE2/B
The table below lists and describes module-defined data types for the 1794-IE4XOE2/B analog input module. It includes information for input (as indicated by an "I") and configuration (as indicated by a "C").
TIP:
FLEX I/O is based on 16-bit INTs and not 32-bit DINTs. This may decrease performance with certain instructions.
Module-defined Data Type: AB:1794_IE4XOE2:I:1
Series B
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 bits are set to 1. |
Ch0InputData Ch1InputData Ch2InputData Ch3InputData | INT | Decimal | Input data for the selected channel. |
Status | INT | Binary | Contains input status. |
Ch0InputUnderrange Ch1InputUnderrange Ch2InputUnderrange Ch3InputUnderrange | BOOL | Decimal | Indicates either a broken or open wire, or input current at or below 4mA. |
Ch0OutputOpenWire Ch1OutputOpenWire | BOOL | Decimal | Indicates the corresponding current output channel is open. |
PowerUp | BOOL | Decimal | This data type is set when all configuration data types are in an unconfigured state. This data type is used for Series B modules only. |
