MicroLogix 1000: addressing syntax
Data files contain the status information associated with external I/O and all other instructions you use in your main and subroutine ladder program files. In addition, these files store information concerning processor operation. You can also use the files to store "recipes" and look-up tables if needed.
These files are organized by the type of data they contain. The default types for the data files (0 - 7) are:
Output | (file 0) | This file stores the state of the output terminals for the controller. |
Input | (file 1) | This file stores the status of the input terminals for the controller. |
Status | (file 2) | This file stores controller operation information. This file is useful for troubleshooting controller and program operation. |
Bit | (file 3) | This file is used for internal relay logic storage. |
Timer | (file 4) | This file stores the timer accumulator and preset values and status bits. |
Counter | (file 5) | This file stores the counter accumulator and preset values and the status bits. |
Control | (file 6) | This file stores the length, pointer position, and status bits for specific instructions such as shift registers and sequencers. |
Integer | (file 7) | This file is used to store numeric values or bit information. |
