Module Data Types 1794-IB8
The table below lists and describes the module-defined data types for the 1794-IB8 Digital 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. Using 16-bit INTs in instructions that are optimized for 32-bit DINTs may decrease performance with certain instructions. |
Module-Defined Data Type: AB:1794_IB8:I:0
This module-defined data type does not apply to modules having Rack Optimization selected for the Comm Format and does not appear among the Module Tags in the RSLogix software.
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. |
Data | SINT | Binary | Input Data - Input data for the module. |
